My Whirlpool refrigerator runs too cold in the fresh food compartment. It was suggested that I replace the thermostat which I did but it still runs too cold. Even if I set Freezer temp to max (6deg) and refrigerator to max (46 deg) food still freezes. The last search I did suggested the thermistor (12002355). Where is it located on my model and will this fix the problem?
You will want to check the damper to make sure that it is operating. You can test this by turning the controls down to where it goes to off. If the damper door does not close at this point then replace the damper. If the damper checks ok then remove the light cover and using a flat blade screwdriver, there are 2 slots at the back of the controls. Put the screw driver in and push the clip that holds the control in place. Once done then you can lower the controls and the sensor is located in the control box.
My refrigerator is at 32/33 despite setting it at 46. To test the thermistor I have to remove the light assembly. It doesn't have screws, and it is not clear how it comes off. I don't want to break it. Does anyone have a video or more detailed instructions. Also, if I can test it at the board, are there detailed instructions on how to get to the board and test it? I am very handy, I just need details. Thanks.
When you pull your refrigerator out from the wall and get behind it. There is a cover on the back that is held in by 4 1/4" screws. You remove the screws and cover then you would remove the plastic cover over the control board. Once this is done you would use a multimeter and on the J3 connector check from pin 1 to pin 5 which would be a white with blue stripe wire on pin 1 to white with Orange stripe to Pin 5. You will check the resistance of the thermistor to make sure that it is good. The resistance value should be as the following. At 77 degrees 10K ohms, at 36 degrees 29.5K ohms and at 0 degrees would be 86K ohms. These values are plus or minus 1%.
Everything in refrigerator is freezing. What can I check?
Answer Hello Jim,
This can be poor air circulation/incorrect unit settings, a bad thermistor 12002355, or a bad Jazz board W10503278.
Were is the Thermistor for this unit for the fridge side and how do I replace it or see if it is working?
To test the thermistor you will want to check for resistance. The resistance values are as follows, 10K ohms at 77 degrees, 29.5K ohms at 36 degrees and 86.3K ohms at 0 degrees. The refrigerator thermistor is accessed by removing the damper cover by removing the 1/4" hex head screws holding it in place. The thermistor will be located under the cover.
Were is the defrost thermaster suppose to be?
The part number for the defrost thermostat is 67003426 and is located on the evaporator assembly in the freezer compartment behind the freezer wall.
My freezer is freezing but my fridge part is as warm as can be what might the problem be Please?????
Answer Hello Char. You may have a defrost issue. Check and see if there is any frost build up on the evaporator coils in the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the control board. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
In Whirlpool refrigerator, ice frosting over and cooling in refrigirator is low. Model is professional deluxe?
Answer Hello Manikanta,
This sounds like a defrost issue. I'm sorry but this is as far as we can go without the model number from the units' I.D. tag so we can look up the configuration and the specific parts in the unit you have in your home. I apologize for the inconvenience and we appreciate your patience and understanding.
Food freezes in the bottom of ref. and ice builds up on back of freezer. Then ref. does not get cold enough
Answer Hello Darlene. Make sure the fan motor is working good. If so, and the coils frost over, It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the evaporator coils in the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
What does a thermistor do?
Answer Hello Steve. It changes in resistance based on the temperature so the board knows the temp inside the unit.
