Where is the refrigerator thermistor for this model refrigerator
For model number GI5SVAXVQ01
Hello Jerry, Thank you for your inquiry. There are two thermistors in this fridge, one in the freezer and the other in the fresh food compartment. The one in the fresh food compartment is located in the ceiling in the light module, you would need to remove the housing and cover to access it. The one in the freezer is at the back corner with a cover over it, you would use a screwdriver and insert it into the tab at one side to remove the cover and access the thermistor inside the cover. Hope this helps!

Where is the thermistor located on the Amana afi2538aeb?
For model number AFI2538AEB
Hello Amy, thank you for your question. There are two thermistors in the appliance. One in the freezer section behind the back wall, close to the evaporator. And in the fridge section it is toward the back wall of the fridge around the light bulb area. I hope this helps!

Hi. My fridge will be working well for a couple days, then the freezer will get warm to the point the food will start defrosting and ice cubes start melting. It will turn itself back on eventually and work fine for a couple days again. Then it happens all over again.There is visible frost from time to time. This is only happening in the freezer. I was seeing on the website about the defrost thermostat and thermastor. I would rather not change parts by trial and error, and get the right part first. Can you help. Thank you
For model number AFD2535DEW
Hi Andrew, Thank you for your question. To verify which part is causing the issue before you purchase one, you will need to test them with a multimeter. You will also need to check the run capacitor, the compressor start device, the evaporator fan motor and the electronic control board. I hope this helps. Thank you and have a great day!

My fridge is a Maytag, model mfi2266aes about 10 years old. For the past 2 weeks now everything in the fridge is becoming frozen including vegetables, milk, soda, juice etc. We had this problem for a duration of time also about six months ago. I've made a couple of phone calls to some tech. Places recently. Can i assume most likely this maybe the thermistor that needs replacing? I have ordered one hoping i get lucky and this rectifies the problem. I have ordered part ps2003772. Thanks
For model number MFI2266AES
Hello Robert, thank you for writing. Yes, this replacement Thermistor for your model will most likely fix the issue. You may also want to consider the Control Damper part PS11748673. We hope this helps.

    Freezer cold, refrigerator warm
    Overload relay accessible from back, by compressor unit. Very easy to change out. Diagram from your site placed defrost thermostat in same area.It wasn't. Found another diagram, showed it in refrigerator light area, took that apart, not there. Yet another diagram showed it in the duct work area at back of refrigerator cabinet. Not there. Finally removed back of freezer compartment, found thermistor and thermostat with the fins. Clipped wires, wired in parts, quick fix. Longest amount of time was spent finding the old parts to replace them. Actual replacement took less than 15 minutes. Refrigerator holding at 35 degrees set on 2 now, better than ever. Total cost, less than $120, doing iy ourselves....priceless.

    The refrigerator was freezing most products
    Remove the light cover. Use a flat head screw driver to push in the tabs on the back of the program mount and pull down to expose the computer board. The Thermistor is clipped on under the vent holes on the right side. Cut both wires to remove the old thermistor strip a 1/4 inch off the remaning wires and the new thermistor wires twist both ends together crimp on the wire caps snap in the new thermistor reinstall the program board until the retainer clips snap into place, slide the light cover back on.

    Freezer temperature goes down to -20*F before compressor stops but refrigerator side remains normal 38*F and compressor makes a grunting noise while running.
    Unplug ref then remove lower(freezer) panel plus trays and thermistor’s cover/holder then remove the evaps cover. I found the evaps all frozen up. Cut and remove old thermistor, strip wires 1/2 inch then cut the new thermistor wires to length and strip 1/2 inch, use the enclosed insulated crimp type connector and put back everything in the reverse order. It works great afterwards.

    FREEZER WOULD NOT DEFROST.
    I initially tested the heating element and defrost thermostat using an ohm meter. the defrost thermostat was incased in ice, so I replaced it first. The refridgerator worked for about a week and then froze up again. I then replaced the thermistor and the unit is working as designed.
