Brand: Whirlpool Model Number: WRX735SDBM00 Main Symptom: Fridge doesn’t keep consistent temp, ice maker not getting cold enough to make ice What happens & when: Recently had an issue where freezer was cold but fridge was not. Replaced the Evaporator Fan Motor W/Harness after a full 24hour defrost. That worked for a couple days and then we started getting melted ice/dripping water and the fridge was around 50. Then I replaced on the damper in the ice maker. Same thing, normal operation for a couple days and then the fridge is back up to 50 and the ice was melting and dripping water out of the dispenser. If I remove the ice maker tray that catches the ice, the fridge returns to normal temps… I am stumped

If you unplug the power supply cord and remove the ice box harness, the thermistor can be tested for resistance when it is placed in a cup of ice water. Does it measure around 7964 Ohms? If it does, it can also be tested at a room temperature of 77 degrees and it should measure around 2700 Ohms. Does the thermistor measure too much differently than this?
I just replaced the thermistor in the freezer compartment since it is part of the Evaporator Fan wiring harness. Is there also one in the fridge where the ice-maker is?
Got it, I’ll give that a try. I was thinking there is an airflow issue because if I removed the ice tray, them temp is at normal. When I re-insert it, the temp goes back up to around 50-52.
This could be a control board issue, but ruling out the ice box thermistor and the fresh food thermistor would be a good approach since the freezer thermistor and the damper have already been replaced.
