True TUC48FADA Freezer Questions & Answers
True tuc 48 f temp not consistant ranges from -5
Make sure condensor (outside) fan and evaporator (inside) fans are running smoothly. make sure no ice is develping on any parts compressor or evaporator. (usually after running for 4 hours or more.) While looking at evaporator and condensor make sure they are clean with no lint or grease on them. If dirty they need to be cleaned. At minimum with brush. Pressurized air is better we used a co2 tank with 2 foot hose. just dont blast them too fast and bend anything. If its greasy it will need special cleaners from the HVAC supply and can cause corrosion and staining of your freezer if done improperly.
Check door gaskets for holes and crack.
Watch usage make sure doors being closed properly.
If all checks out then its 1 of 2 things. the thermostat control and sensor. or the coolant charge may be low or high.
Thermostat can go bad but is usually the sensor is not tightly clipped to evaporator. check and make sure its snug against the (Clean) pipe.
For charge the small line should not always burn your hand if touched and the cold line should not have ice on it. have proffesional check if necessary the pressures are very hard to get accurate in small machines.
I have a true tuc48-f freezer..Problem: Frost
It seems you have diagnosed your own problem.
Check the defrost circuit. It appears your defrost cycle is not working.
Also,check the door seals closely.
A loose or broken door seal can contribute to these symptoms as well
No door heat
The Mulluen heaters will be Built into the frame not in the door.
On freezer True T-23, the compressor works around 5 minutes and turn off for around 5-6 minutes and start again for another 5 minutes. I need help
That is what it is supposed to do. It is called cycling and switches off when the set temperature is reached. It is a commercial freezer, so if the door opened and closed often, that is normal?Commercial freezers and fridges have an item called a 'Clixon' that cuts power in the case of the compressor overheating. When was the last time the fins on the compressor coils were cleaned? Could also be a bad door seal letting cold air escape. When you close a freezer door on a unit like that, it should be really hard to open straight afterward due to the suction. Could be a faulty thermostat. Turn the temperature to the warmest setting and see if it still does it? If it does, you need a new thermostat.I just retired after 52 years in catering.https://www.katom.com/598-T23F.html?gclid=CjwKCAiArbv_BRA8EiwAYGs23PKtEzF60_OMVNpHXBlGjHQNdpp0pDZsu0G0lFLqVy2p4qIybG9n8xoCwEMQAvD_BwE..
Why is jenn air jcd2389ge hot around front freezer door frame?
The heat at the opening of refrigerator is usually a sign the condenser coils are dirty. Check the condenser coils for a restriction underneath the unit. Dirty condenser coils will cause poor air flow over the coils and compressor. Poor air flow will cause a lot of problems, including overheating the compressor, the refrigerant and the copper lines. This will destroy your sealed system. The coils need cleaning at least once a year, more often if you have pets.
I couldn’t determine if your unit has an “energy saver” setting. If so, turn it on. Not all refrigerators have energy saver. This is on units with emilion heaters in the wall around the door gaskets. The heaters are to eliminate condensation around the door. Turning ON energy saver turns OFF those heaters. You should notice a change quickly if it’s the heater causing the heat, that is, if you have that model.
Cleaning the coils will need a day or two to allow things to cool down before you notice a change in the heat around the door.
True 49f fans stopped running.
Compressor still runs. Fixes? Troubleshooting steps?
I am assuming you are relating to the evaporator fan(s) not running. If this is the case, some units have a 'Klixon" type thermostat in the evaporator so when the evaporator coil temp reaches a predetermined temperature, the fans come on. You may have a bad "Fan Delay" (Klixon) or the coil is not reaching the proper temp to activate it to turn on the fans. I would check the wiring diagram on the unit for this part to see if this unit has it in the system.
