By: Frigidaire
Part Number: OEM18835329
Manufacturer Part Number: 5304512375

This is a thermistor-style temperature sensor that monitors the evaporator coil temperature in a room air conditioner. It sends temperature readings to the control board so the unit can regulate cooling cycles and prevent the evaporator from freezing over. Replace this sensor if the air conditioner runs continuously without cycling off, fails to cool properly, displays an error code, or if the evaporator coil ices up excessively.

Questions & Answers

For Frigidaire Air Conditioner Evaporator Temperature Sensor (Part Number: OEM18835329)

1 Answer

Cooter, if the compressor and fans operate but cool air is not produced, there would be a sealed system failure that would require an EPA-certified technician to diagnose and repair. If the compressor does not turn on but the fans do, the main control would need to be tested for 120VAC from the red wire at connection RY7 to the blue/white wire at connection P9. If there is not 120VAC, the control has failed. If there is, the capacitor would be a likely cause of failure.

Scott for Model Number LRA18HMU212

The controls seem to work fine, the power comes on and I can change the mode from A/C to Heat and I can change the fan speed, etc.  The Fan runs perfectly.   The A/C will cool, but it will never turn off...just keeps cooling no matter what I have the temperature set to...just keeps cooling.    Back in the winter, the heating elements wouldn't come on.  Again, the fan worked and the controls worked, just no heat coming out. Please give me kind of a list of parts that might be causing this issue and I will replace them one at a time to see if the problem resolves. Since right now it's summer time I am most concerned about getting the A/C up and running. Thanks!

Scott, There are only a few items that would cause this. The thermistor would be the main issue or the main control board. The thermistor will be part number 5304512375 and the main control board 5304483065.

Amanda, if the compressor and the fans are running, it should be producing cold air, if not, you have a failed compressor or sealed system problem.

Hello Steve, this is common in window units. Fan will always continue to run even when the compressor shuts off. This is for air circulation in the room. Thanks,

Dusty, This issue would be caused by a relay on the main control board that is bad and would need to replace the main board.

Wayne, You will want to check on the control board at the connection for the compressor and make sure that there is power going to the compressor. If there is power then the issue will either be a bad capacitor or a bad compressor.
