Question about GE Refrigerators

1 Answer

Zisb480dmc monogram, replaced Fresh food damper(-17 in freezer, 48 in refer), did not solve. Replaced Main board and fresh food thermistors, worked 10 days, problem became 44 in fresh food -27 in freezer. replaced freezer thermistor- -27 in freezer 38 in fresh food section. Evaporator is clear( no frost), and I'm just about out of ideas. Last ditch effort is evaporator thermistor. Any thoughts?

There's a temp sensor on the evap coil part WR55X10025,i would change that out and when you changed the board if there's a wire in the second pin of the connector with ithink 9 pins on it you have to cut the wire that's in the second pin,if there's no wire in the first pin but one in the second pin then leave it alone,look at the paper that came with the board and it will tell you what connector it is,let me know what you find,the old sensor has like a black piece on it where the wires come out of it,the new one is all white but you should change the sensor when you change out the board

Zis480mnc ge monogram built in refer temp varies from 34 to 48 several times a day.


Try replacing that evap thermistor. The diagnostics on thermistors can be wrong. If it is rounded on the end, replace it. There is a damper between the freezer and refrigerator. There may be a refrigerator fan motor in the damper assembly, It could be bad. It could be a bad control board. When you run diagnostics there is one function that checks all the fans.

What else can I check - my fresh food side of fridge is still too warm, freezer fine.


GE refrigerators use a board to control cooling and defrost functions. The fresh food compartment also utilizes a motorized damper, and some models even have a fresh food fan. Air enters the fresh food compartment at the top left corner, and the return air is also in the left wall down near the crispers. Both paths must be clear.

Ge refer model psc25mstass fresh food section not cold enough freezer cooling fine


I realize this is an old post but information is always helpful if it is correct. I have a GE Model TFX22ZRB, Main tools needed are a refridgerator thermometer, a cheap multimeter, 1/4" hex driver, phillip screwdriver and regular blade scewdriver, above all, alow time for tempeture change when measuring tempeture. The freezer is running at -8 degrees C or aproximately 28 degrees F. I don't care about 1 or 2 degrees at this point in the freezer, the defrost system is working ok, The freezer is cold enough. The fresh food section is running at 48 degrees F, the damper is wide open between the freezer and cold food section, I manually removed the damper door and controls since I am only interested in seeing if I can drive the fresh food section colder. Looks like the fresh food thermostate controls the compressor and not the damper to shut off the cooling process when the tempeture gets cold enough. Since the fresh food section does not get cold enough (this should be in the uppers 30s F) there is no need to move the fresh food thermostate out of the normal range setting (mid point in my case) with the operator control. Defrost heaters ok, this unit uses 2 heaters hooked in series with a evaporator coil thermostate also in series with the heaters. Heaters aproximately 25 ohms total risistance, coil thermostate open at room temp and closed when below 32 degrees. Only other item in circuit is the defrost timer, this can be manually advance to open and close the defrost circuit, in my case, when in the defrost mode, the evaporator fan stops and the heaters heat up. The defrost timer in my case has a 12-16 hour cycle time and a 30 min defrost time, so in a 24 hour period I may get only one defrost cycle. One item of importance. make sure something has not fallen in the lower back or the fresh food section of the refridgerator to block the air flow return, this will effect the coo;ing process. Now with the damper wide open, the defrost circuit working ok I am going to look at the evaporator fan itself for speed, shifted blades or the air circulation between the freezer and the fresh food section, I have cleaned the condenser coils but I am leaving the condensor and compressor out of the equation since the freezer is cold enough but at this point I am considering the possibility, I may need to replace the fridge if the compressor is not working to par.

I have a feeling that the temperature control board is not the problem. The fresh food compartment has two thermistors that relay information to motherboard through your control panel. If thermistor is bad or covered by an item it will continue to cool and freeze fresh food. Your air damper between freezer and fresh food compartment may also be wide open.

My GE Profile fridge side isn't staying cold, but the freezer is. There is no thick frost built up in back of the freezer side so I know it isn't the defrost heater. Could it be dirty coils underneath the...


There are a couple of things that can cause this. Thermistors, mainboard, fan and damper.
Start with the cheapest.
1. Check Thermistors - Pull J1 and check connector pins 1,2,3 and 4 to pin 5. They should beapproximately 15Kohms. In your case, the freezer thermistors (pin 3 and4 ) should be higher than the fresh food (pins 1 and 2).
2. Fan and Damper - Fresh food fan should be on and damper from freezer to fresh food should be open. If not, check that fans spin by hand and damper doesn't look damaged
3. At this point it is most likely the motherboard.
