Evap motor runs when in defrost but when you close freezer door motor stops running. Do you think it may be the computer board. The customer is advising one morning temps in freezer was at 30 degrees then later dropped back down to normal.

Air temp in freezer could be up if unit is in defrost cycle, but temp of packages would not vary much from such a short temp increase. Fan will turn on if door is left open for several minutes to prevent damage from freezer light bulb heat. By the way, this is a Fix-Ya to a fellow servicer.

Delfield coldpro freezer mod#f2fh evap frozen. what is most common problem?


Look for: defrost timer not moving, i.e. locked up.
Contacts on defrost timer not making circuit to the defrost heater.
No power to heater.
Heater not working, open element, burned out, etc.
Defrost terminator defective. Not letting unit stay in defrost cycle. Could also interupt power to heater.
Defrost cycle too short. should be about 20 to25 minutes long and 4 times a day.
Evap fan motor not running or running inconsistantly.
Evap fan running in wrong direction or wrong speed.
Evap extremely dirty which blocks air flow.
Improper freon level.

I'd start with these items. Let me know if I can be of any further help.

this sounds like a control board circuit problem..but first remove perishables and defrost freezer ..turn off or un plug..leave refr door closed..freezer door open..if you have lots of water while defrosting you almost cirtainly have froozen the evap coils solid..freezer cannot work like this..after defrost..plug in and see if temperature returns to normal..if it does it won't last indefinately..your probably have a bad defrost timer and/or evap heater gone bad

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

Freezer works fine but fridge has lost its temperature.


The fridge gets its cold air from the freezer through a vent between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp

..
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

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.

Kenmore fridge bottom freezer. Freezer is cold but fridge is warm


Sounds like the start of a defrost problem, open your freezer and see if the back wall has any frost on it. if so your evap coil is in-packed with ice and it won't be long till you start to lose cooling in the freezer also. If you don't have ice on the back wall check the evap fan motor to hear if it's running ( you should hear it when u open the freezer door or feel the air movement.) note: if the evap fan motor is not running that may also cause frost build up on the back wall of the freezer. If the fan is not running remove the back wall and check the fan wires for 120 volts ac.if you have power replace the motor. Also with the back wall removed you can check the defrost t-stat and defrost element you should read a closed circuit on the heater and with the evap coil frozen you will also read a closed circuit on the t-stat to. If the defrost element or t-stat check bad replace that part, if they check good replace the defrost timer. you can hit the coil with a hair dryer to thaw it out till you get the part you need, that will buy you about 3 days. Good luck hope this helps you

Kemore model 795.7731 bottom freezer


You are probably correct that it is the evap motor. If you are seeing frost on the back wall then there is probably some ice built up around the motor and the fan blade is hitting it.
Try defrosting the freezer and look very closely all around the seal for the freezer drawer. It is common for moisture to freeze in the self closers in the drawer rails and not let the drawer close completely on one side or the other. If this happens the small gap will allow the freezer to frost excessively.
Sorrry to be slow in responding. I have been very busy this week and have not been on line very much.
