The SH (not 5 H) error indicates that the freezer sensor is shorted in the display. The control can't determine what the freezer temperature currently is. You need to check the wiring between the thermistor (temperature sensor/resistor) and the control board. Replace the thermistor if the wiring has no damage. If the wiring is faulty, replace that. If the fault returns, you may have a problem with the control board.
Please add a comment with the model number of the side-by-side refrigerator if you need a parts diagram. I hope this helps.

When you replaced the thermistor, did you check the resistance of the wiring and temperature sensor back at the control board? If the wires are damaged or the connector at the control board has corrosion, the control board won't get the correct signal information. If those are fine, then the control board is probably faulty. Sears Parts Direct has the control board here: https://www.searspartsdirect.com/product/3jlv6aqwdo-0046-253/id-5304512769 . Other repair shops will have this part as well.
I wish that only the refrigerator temperature sensor was faulty. I hope this helps.

It is a warning that the fridge thinks the defrost heater is bad
Frigidaire side by side Model Ffhs2622msu Flashing H on the... H means that the refrigerator thinks the heater is bad. You'll need to pull everything out of the freezer and remove the back panel inside the freezer. You'll see the silver evaporator coils with the evaporator fan above it.

Be aware the fridge works with deadly voltages. If you have not enough technical knowledge, please don't do this yourself.
With a multi meter you can measure if the voltage you apply is entering the fridge. There is not much in a fridge. You find a on / of switch, a thermostat en mostly an override switch too short a thermostat. So if you measure a voltage coming is, follow the wiring and check what the thermostat does. if it won't switch you have the cause. If it does switch, follow the wiring, and if the aggregate gets a voltage and does not run, you have a defective aggregate. I can't think of more.
Good Luck.
you may need a check Freon level to see if its low , usually if u have low Freon level you can touch the condenser fan rails and they should be cold because when it has Freon and it liquefies into gas it creates heat hence the coils will then get warm and hot, if they are hot or warm it may not be a low Freon level issue? I would also check the freezer thermistors , see pics there may be more than 1 thermistor in freezer section , u can also check the compressor ur self to verify as not all appliance techs are reputable or knowlagable
You’re damper inside of fridge not opening y need to put in service mode to check errors codes service diagram location front bottom left side almost over dripping pan
Your Icemaker always makes solid cubes. Goes into bucket. your selection on the dispenser is not being recognized . Could be the control on the door (selector) . Also the selinod that switches from whole to crushed located at the assy behind bucket, Varies ON Model #
The LED above the Ice Off icon should be lit when the icemaker is disabled. It should be off when you want ice from the icemaker. To toggle the setting, press and hold the Ice Off touch pad for 3+ seconds. This is shown in the manual for the FPHF2399MF2 on page 14. Sears Parts Direct has the manual here: https://www.searspartsdirect.com/manual/234cu4elin-001428/frigidaire-fphf2399mf2-bottom-mount-refrigerator .

FREEZER /FRIDGE NOT COOLING: Optimum refrigerator temperature at or below40° F(4° C). The freezer temperature should be0° F(-18° C). Check temperatures periodically. Appliance thermometers are the best way of knowing these Check ur cold control thermostat, ur thermistors in both fridge and freezer ( they should be checked for both ohms and for amount of current being put out as per ur model ), ur air flow vent from freezer to fridge.( to make sure it opens and closes without any restrictions) On thermistors check for A close circuit and amount of ohms not just an Ohm reading. As per ur model. Most should atleast show 1200 ohms. Also Check door seals for leakage.Evaporator coilsPoor cooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited. FAN check to see if it is operating or restricted A fan that is not blowing or restricted will not circulate the cold air properly. Often, the first thing that folks do when their refrigerator starts to feel warm is turn both controls on the coldest settings.This is exactly the WRONG thing to do.Turning the cold control to the coldest settingwillkeep the compressor running longer and make lots of cold air. But turning the air door to the coldest settingclosesthe airway to the food section. Lots of cold air is made, but most of it stays in the freezer section, and the food section actually getswarmer. Condenser Self-defrosting refrigerators all have a set of coils and a cooling fan, usually under the refrigerator, that need to be cleaned regularly. If these coils get coated with dust, dirt or lint, the refrigerator may not cool properly. The coils may appear to be a thin, black, wide radiator-like device behind the lower kick-panel. To clean them, disconnect the refrigerator from the power source, use a refrigerator condenser brush and your vacuum cleaner to clean the coils of any lint, pet hair, etc. You may not be able to get to all of the condenser from the front, it may be necessary to clean the remainder of the condenser from the rear of the refrigerator. May also need to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad? Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next. Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance.. THE COMPRESSOR:If you hear a clicking sound coming from the back of your refrigerator/freezer, then the problem is most likely the compressor, relay and or capacitor is overheating or not getting proper power and will not start.The compressor is the component on your refrigerator that allows your refrigerator to cool. If this component is not working properly your refrigerator will stop cooling. Most of the time the compressor is not the component that has failed. To check ur compressor with multi meter: Disconnect and remove the relay and capacitor from compressor, some located next to compressor in a casing. You wills see 3 prongs coming out of compressor. 1 goes to ur start winding, 1 goes to ur run winding and the center goes to ur ground. Place ur meter connector or prong on the start prong and the other on the ground (center prong) take note of the reading in OHMS for example 5 ohms. Next place meter prong on run prong and the center ground prong agin. Take note of the reading in OHMS. Example 4 ohms Next place meter prong on the start prong and the other on the run prong, now take note of the reading example 9 ohms. Now match the total of this ohms test with the total of ur two separate test. 9 ohms, if they match ur ok give or take 5 percent plus or minus. One more test to make to test of there is a short in compressor attach meter prong to ground prong and rub the other end of meter prong to metal ( scrape the metal clean of paint and test on metal surface not painted surface. If it shows continuity or ohms , u have a short in ur compressor. It should show infinity TO REPLACE RELAY AND CAPACITOR WITH A HARDSTART KIT YOU CAN USE A 3 in 1 start kit for compressors sizes 1/4 through 1/3 HP. And a 5 in 1 for higher H.P. (BE SURE TO MATCH WITH UR COMPRESSOR MODEL NUMBER AND TYPE) The kit includes relay, capacitor, and overload device, pre-wired. The kit will replace all 3 electrical components on capillary refrigeration systems. For newer systems with a run capacitor use proper kit. For smaller horsepower compressors useTJ90RCO810. The wire set up is as follows the red wire goes to the right side of compressor prong, the white wire to the left side prong, the black wire to the center prong, and the 2 other black wires go to the power and the ground connection Lastly you should also check ur THERMISTORS in the freezer and fridge section for continuity OHMS and for amount of OHMS current being put out. In most models around 13000 ( give or take 150 ohms) ohms is required. 1-3 TEMPERATURE CONTROL As the food in the fridge gets colder, it gives off less heat, and the air inside the fridge will remain colder. A thermostat called aCOLD CONTROLwill cycle the cooling system on and off to keep the temperature inside your fridge within a certain range. You can adjust that range using one of the dials within your fridge. On most fridges, all the cold air for both the food compartment and the freezer compartment is produced in one evaporator. Since the freezer is so much colder than the food compartment, most of the cold air that is produced circulates to the freezer compartment. Only a small amount is needed in the food compartment to keep it down to the proper temperature. This amount is adjusted by a smallAIR DOORin the duct between the evaporator and the food compartment. The control for this air door is the other of the two dials within your fridge. If you hear your compressor "short-cycling" (starting and stopping at short intervals) try jumping across the two leads of the cold control thermostat ( in the fridge compartment) with an alligator jumper. You can also check both for live voltage current and ohms- If there is a greenthirdlead, ignore it for this test; it is the ground wire. If the fridge starts running constantly, the cold control is bad. Replace it. To test or change the cold control, first Pull the knob off it and remove any plastic cover plate or housing from it. You will see two wires leading to it. There will also be a thick, stiffCAPILLARY TUBEattached. The capillary tube is the liquid-filled temperature-sensing element of the cold control, and operates in the same manner as a thermometer The air damper, baffle or diffuser is the device that balances the air flow from the evaporator fan housing. This normally is a mechanically controlled baffle or flapper that controls the amount of cold air entering the fresh food compartment. If the baffle is damaged or the linkage to the control knob is damaged, then you may not have enough cold air entering the fresh food compartment resulting in higher than normal temperatures. This baffle or damper will be located where the cold air enters the fresh food compartment.

Fridge/freezer freezing up- and no fan or air circulation: first check the defrost terminator thermostat it may have gone out. Thus not allowing the heating element to melt the ice. AT TIMES The fan usually stops working AND CAN MAKE FUNNY NOISES AS WELL due to ice obstruction when the defrost terminator has gone out and u get ice build up? u can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature. May also need to check the defrost timer, The defrost timer is usually found behind the front grill "toe kick" of the refrigerator. Or in the fridge compartment near middle top section. u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad? Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next. Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance.. Another item to check with a meter is the heating element itself. Located under the evaporator coils. It should show continuity or resistance OHMS WHEN TESTED AT BOTH ENDS OF THE PRONGS . Lastly check the cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit? ALSO CHECK THE AIR FLOW VENT SYSTEM and THERMISTORS At times it can get stuck to far closed or open. Some units feature a digital electric adjusting vent system while others are manually set. Check for any ice build up or other obstruction in the vent damper, see if u can manually open or close it. Some times when u have the settings set to the highest it closes off one area while allowing to much cold air flow to the other area! THERMISTORS in the freezer and fridge section for continuity OHMS and for amount of OHMS current being put out. In most models around 1300 ( give or take 150 ohms) ohms is required https://www.youtube.com/watch?v=zmdsBkO46dk defrost therm. https://www.youtube.com/watch?v=6SJN8oaA2XE https://www.youtube.com/watch?v=buX9KcZo2c0 https://www.youtube.com/watch?v=gVXT7pZyk_o https://www.youtube.com/watch?v=53ZFeiWgtuk God is so good: so this is why I give free advice so please thank him not me. Fridge FAN CONTINUALLY STAYS ON OR SHUTS OFF WHEN DOOR IS OPENED: NORMALLY WHEN THIS HAPPENS U EITHER HAVE A DOOR CONTINUALLY OPEN ISSUE OR A BAD DOOR SEAL LETTING AIR IN AND CAUSING FAN TO OVERWORK ITSELF. ANOTHER CAUSE CAN BE DIRTY COILS AND CONDENSER AND LASTLY NOT TO COMMON IS A SHORT IN THE FAN SYSTEM ITSELF. A MORE PROBABLE CAUSE COULD BE BAD THERMISTORS OR EVEN COLD CONTROL THERMOSTAT ( WHEN THE THERMISTORS OR THERMOSTAT DO NOT GET/GIVE A PROPER READING, THEY CAN CAUSE THE FAN TO CONTINUE TO OPERATE AS THEY FAIL TO RECOGNIZE OR REGULATE THE PROPER TEMPERATURE. http://www.appliancerepair.net/refrigerator-repair-1.html
There is some truth to it. Refrigerant needs to flow from high pressure to low pressure, and refrigerant pressure is directly proportional to temperature. Once the temperature drops below 40*F, for the outdoor coil, refrigeration efficiency is lost. Some heatpump units need auxiliary heat because. Cold refrigerant condenses, into a liquid, and a compressor will not compress liquid, why its valves and internals would chatter into pieces. There is such thing as compressor crank case heaters, or belly band heaters. A heater removes, evaporates liquid refrigerant from within a compressor, it is protection.
I would get a compressor heater, wraps around the compressor belly, near 50 watts, and can use a relay to switch off the heater when the compressor runs, or let the heater work continuously.
