You can remove the fan and apply the normal voltage for your home or use a test meter to check the wires going to the fan. It should be the house voltage. Let me know, Sea Breeze

sounds like the compressor is not running. The condenser fans are located at the compressor. The fans in the conditioned space are the evap fans. A refrig usually does not have any device controlling the evap fans, they are to run 24/7. Freezers have other controls. Start there and let me know if I can help further.

Model 106 56569400 - Freeze side appears to be Ok. Refrig side not cooling to set temp 37. Current temp is 55-60. Door appears to seal properly.


If you have heavy frost build up on the back wall of your freezer you have a defrost problem. One of three things. Defrost timer, Defrost T-stat or Defrost heater. Usually problem is with the T-stat. If no frost make sure the evap fan is blowing. You should be able to hear a fan noise when opening freezer. If no fan noise replace evap fan which is located half way up behind freezer wall. Good Luck

HELP!!__CALLING ANY GE FACTORY TECHS


You say " all thermistors check fine " , how did you check them ? Did you check for the 5-8 DC volts at the main control board , for the thermistors ? Did you do the diagnostic check for the thermistors from the control panel ? I'm sure you know there are 5 thermistors , since the refrig has the dual evap . Possibly the # 5 is bad , since it is the freezer temp " controller " , yet if it tells the board it's not cold enough , it still sends refrigerant to the refrig evap . Since the refrig evap has 2 fan motors , can't remember if there is a damper there also . Maybe when the # 3 thermistor is satisfied , it only cuts the fans off , even though refrigerant is still going thru the refrig evap .

Check to make sure the evap fan is running.
IF so, then let unit defrost, then turn back on, check for air comming thru top of refrig vent, if air moving ok, then let run for a few days and see if refrig warms again, if so then check for frost build up on back wall of inside freezer, if so, you have a defrost problem. With a defrost problem, defrost heater may be bad, defrost timer/electronic control may be defective. Either way, in most cases it is a defrost problem unless you don't have air moving and fan is running in this case you have a damper door problem inside air duct in refrig.

GE GSH25JSTASS doesn't freeze or cool


Ok, first off, replace all thermistors, freezer (2) & refrig (2). Then check that evap fan is working properly. This is a DC volt fan, not ac volt. There have been some issues with these, I would replace if problem continues.

How this box works, main control board monitors everything from how many times doors are open, how long they are open, how and when I/M drops ice, etc.... Every so many hours, depending on how many times the doors are open, you got ice thru the door, etc... it will shut down and go into defrost mode. When it is time for defrost mode it will run refrig into a "sub zero" state, shut down evap fan, run deeper into sub zero effect, shut down compressor when the thermistors say it's cold enough, turn on defrost heater that melts any frost in evap, then turn compressor back on for a few minutes, then turn evap fan back on. Most techs think that the mother board is defective when in fact the thermistors are not measuring temps correctly within the whole unit. If the thermistor say, hey mother board I'm only 60 degrees in the freezer, then it will keep running the compressor trying to get to zero or -1 or till the darn thing freezes up and stops moving air.

Find another tech to work on your unit, one that has some electronics background and/or computer knowledge. It takes a electronics & computer degree to work on these units and understand how they function.

Doors, some of the new frigs have magnetic door gaskets, if it is not staying shut, replace door gaskets. If door stay open or is leaking air (especially around ice shoot) it can cause some really weird stuff to occur, like thermistors saying I'm cold at the inlet to evap but not at the top of evap and mother board will try to correct it's self by running longer. One other thing about door gaskets, if the drain plug in the evap area is frozen or plugged up, doors won't shut properly and stay shut.

For one thousand dollars, I'll come to Florida and fix for you, 200 to fix refrig and the rest for a good time at Disney World (LOL). Good luck. Contact GE for repair on this unit if you can't get good results from your repairman. Their people, like me, go thru extensive training on these boxes. You can thank our goverment for the energy codes that have gone into effect over the years requiring mfgs to have to keep the cost of running these refrigs down as low as possible, the only way to do this was to computerize these boxes. Good luck

Refrigerator has a clicking sound and does not run


Replace the motherboard (part # WR55X10942) but be careful to check that the evaporator fan (inside the freezer) turns on when you power up the refrig again. A bad evaporator fan motor can take out the motherboard. If compressor starts with new board but not evap fan, unplug immeadiatelly and replace the evap fan motor to save new board.

My GE refrig is side-by-side & 15 yrs. Freezer is good, refrig is not cooling good. its 55C instead of 35C on the coolest setting


Check the evap fan inside the panel in the freezer. Try giving it a spin and a drop of oil. Replacement fan runs about $95

Our 4 year old GE side by side frig suddenly warmed to 64 degrees. Freezer stopped freezing and is at 43. Motor is running.


Really need to know what motor(s) are running (compressor, evap fan inside freezer compartment, condenser fan under fridge)?? Of course, check your temperature (thermostat) settings. Side-by-sides usually have 2 of them. They should be labled for refridgerator and freezer. The freezer control usually only opens a baffle from the freezer compartment to the refridge compartment. The refrigerator temp control is the one that controls the compressor on-off cycles and the temp of refrig compartment (this keeps the refrig compartment from freezing the milk and cokes) If the freezer control/baffle is set too far open, this will cause the refrig temp control to shut off too soon for the freezer temp to get low enough. These controls can get bumped out of the correct setting accidently from time to time.
To check the following, the fridge has to be running, or in a condition where it "should be" running: If compressor is running (condenser fan should be too), check if evaporator fan (inside freezer) is running. Open (freezer) door and hold door light switch in when you check evaporator fan operation (some fans stop when door is open) If it is not running you may have a bad evaporator fan motor. It could also be a bad defrost timer, causing the evaporator (also inside back of freezer) to ice-up. This blocks the air flow over evap. Also, there is a defrost terminator switch on the evaporator coil that stops the defrost cycle when coil is clear of ice/frost (but timer hasn't ended defrost cycle). If it is defective, that could also keep the fridge from going into the defrost cycle, or taking it out too soon. If it is the timer, change the defrost terminator as well. Depending on how handy you are, you may be able to check/change any of these parts yourself. If you don't know much about elecrical stuff, you should leave it to a repair tech. Hope this helps.

Maytag PBF 2255 HEW refrigerator Freezes up, won't defrost


To rule out the evap fan.

The evap fan should run all the time except when in the defrost mode.
