Dear All, I need recommendation to change some elements in DW9116 to run by 220-230 V AC. I appreciate for support. Alik

It sounds like you may be experiencing issues with the heating element on your Frigidaire window AC/Heater combo unit. Here are a few things you can try to troubleshoot the problem:

1. Check the thermostat: Make sure that the thermostat is set to "Heat" and that the temperature is set to a level high enough to activate the heating element.
2. Check the air filter: A dirty air filter can restrict airflow and prevent the heating element from functioning properly. Clean or replace the air filter if necessary.
3. Check the heating element: The heating element may be faulty and needs to be replaced. Consult the manufacturer's manual or contact the manufacturer's customer service for further assistance.
4. Check the blower motor: The blower motor may be malfunctioning and needs to be replaced by a professional technician.
5. Check the wiring: Check the wiring and connections, ensure that all the wiring is securely connected and that there is no damage to the wires.
6. Check the fuses: Make sure that all the fuses are working properly and that they are not blown or tripped.

Keep in mind that attempting to repair an AC/Heater unit can be dangerous if you are not familiar with the proper procedures and safety precautions. It's best to let a professional technician handle the repair.
If the problem persists, it's recommended to contact the manufacturer's customer service or a professional technician for further assistance. They can inspect the unit and determine the cause of the problem and provide a solution.

The DW9116 is actually a 120 volt charger so it should cope with 130v AC supply, what is the supply from?

It is normal for a standard 110v supply to run at around 117V

See THIS INFO on power supplies

Hi LiLo

Is this unit designed to pre heat the water to a given temperature or is it On-Demand. Eg the heater turns on only when a tap is turned on?
Either way, you need to check if AC is getting to the heater by using a multimeter of a Neon Light tester.
Once you find out if it's got AC at the heater then it's a simple matter of following the AC to the actual element.
If the Element shows 240v across the element but does not heat up then the Element is open circuit and will need replacing.
If there is some control mechanism stopping the element from getting 240v then you've found the problem. The Control circuit or temperature sensor.


Good Luck

Go to the US post office where they have a specialist who will assist your. J.

If it works on gas and NOT electricity then the heating element is not getting power or the heating element is open. The heating element is located on the tubing just aft of where the pilot flame is on the bottom of the copper tube. You should check for power to the heating element and with power off perfom a continuity check on the element. I really do not at this time think you have a heating element problem.

There is a 120VAV element a AND a 12VDC element. The chances of both of these failing at the same time is pretty slim.

There is a note in the manual:
If the gas only pushbutton is depressed the
lamp will illuminate green and the refrigerator
will only operate on the LP gas mode, even if q
120 or 12 volts are available.

Another significant change in the third
generation A.E.S. system is how the 12 volt
heating element mode operates. As with the
first and second generation series, the 12 volt
heating element circuit is energized by the
ignition lock terminal. This terminal receives
its DC voltage from a wire that runs from the
run side of the vehicle’s ignition switch to the
refrigerator’s ignition lock terminal. This
allows the 12 volt heating element to be
energized only when the RV is traveling down
the road.
When the ignition lock terminal is energized
by the ignition key, the printed circuit board
must see at least 13.3 volts DC for a period of
40 seconds before the system will activate the
12 volt DC heating element.
If 13.3 volts is not achieved in this time frame,
the electronics will light the LP gas burner and
the refrigerator will operate on the LP gas
mode.
LOWER THAN 13.3 V.D.C. =LP Operation

If the battery voltage remains low after the
delay cycle, the automatic controls will light
the refrigerator on the LP gas mode and stay
on the gas mode until the printed circuit board
sees approximately 13.3 volts DC to the
terminal block.

For proper cooling on the AC mode, the AC
voltage to the refrigerator should not vary
more than 10 percent from the voltage rating
on the heating element. Heating elements used
in Dometic refrigerators could have a rated
voltage of 110 volts, 115 volts or 120 volts AC.
Because of this, the power requirements for
each differently rated heating element will
vary. For example, if a heating element is
rated for 100 volts, the acceptable power range
would be between 99 to 121 volts AC. If an
element is rated for 115 volts, the acceptable
power range would be between 103.5 to 126.5
volts AC. If the heater is rated for 120 volts,
the acceptable AC power range would be
between 108 to 132 volts AC.

The unit to operate on either AC or DC must have 13.3 volts to the unit. I think this is where your problem lies in that the battery voltage is less than 13.3 VDC


If all of that checks good just repsond here and I will help you. There is still more that can be checked.

Thanks for choosing FixYa.

The low pressure switch is located on the accumulator, and you only need to remove the connector to the low pressure switch and jumper the wire connector to by-pass the low pressure switch, however I would not recommend doing so because it is there to keep the AC compressor from being damaged due to running it low on R-134a.

If you are trying to charge the AC system you do not need to by-pass the low pressure switch, just start the vehicle and turn the AC on to maximum, then charge the AC system and when there is enough pressure in the system the compressor will come on, and then just continue to fully charge the AC system.

Now can someone help me find the schematic for this model? DW9116

May just need new heating element. Need to check for 120VAC, coming from connectors on circuit board to element, if yes, change element.
Make sure it's on AC operation, and calling for heat, you may have to leave door open on fridge, just to make sure it's calling for heat, or try on gas, if it lights, then you know it's calling for heat, then switch to AC operation and check for the proper voltage to element. If you need more instructions, let me know.
