Questions & Answers

For Ge Start Relay (Part Number: OEM18102921)

Masapell for Model Number PTS22LCSARWW

I am trying to troubleshoot a unit that has not been cooling (freezer and fridge section) a couple of times out of the past two weeks. The unit is in a staff kitchen that is used by multiple employees, so my first task is to rule out "user error", like a door that was left open. Since it has happened twice, I suspect something might be up. The fans were both running when I first checked the unit, but the compressor and coils were completely cool to the touch. The compressor was not running at all. I removed the relay and everything seemed fine with it. After visually inspecting a few other items, I put the relay back in and plugged the unit in. It seemed to run for a little while, but then cycled off. When I went back to check after about an hour or so, the unit was running and cooling everything back down. The unit has digital temperature displays for both fridge and freezer and both appear to be working fine. Where should I go from here? I did measure voltage on the relay while the unit was running and was around 144 volts. Would this potentially be a relay that is going out or something related to the capacitor or overload switch?

John, Based on the model number this relay is the correct part for your unit. Based on the wiring schematic, it shows that there are only 3 wire connections for the overload and the relay. Red which goes to the overload, black which goes to the start side of the relay number 3 terminal and orange goes to terminal number 2.

Hello Douglas! Unfortunately, the relay WR07X10029 has been discontinued with no further replacements or cross references available and our company is unaware of any other available sources. Sorry about that!

Hello Barry, Pull the unit out from the wall and unplug it. Remove the bottom rear cover and take the device off of the side of the compressor. If it rattles when you shake it, the start relay WR07X26748 has failed and needs to be replaced.

Hello Herb, You may want to check your freezer temperature. This icemaker should cycle approximately every 2 hours as long as the temperature is correct. If temperature checks ok you may want to check to make sure icemaker is getting proper water. Without proper water flow it will take longer to make ice and fill up bin.

Hello Dhiru! Unfortunately, we do not have any information on a TR4RD 3 CF ref or the part number 1042122. You may have to contact the manufacture of the compact refrigerator to verify the part numbers and information. Sorry.
