My frige is not cooling, but my freezer part is cooling fine.
Answer Hello JC. Check the fan motor in the freezer and make sure it is working properly. If so, look for frost on the back wall. If there is frost, then It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of 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
I have replaced the defrost timer and the thermostat and have checked that the defrost heater is o.k. The refrigerator still runs all the time and the freezer section as well as the refrigerator is down to zero degrees. What do I do now?
Answer Hi Larry. When a cooling unit continuously runs as if the temperature has not been met, you would think it may be the cold control thermostat or a thermistor out of value depending the model # . First double check if the unit is level front to back and side to side. Then quickly see if the door gasket is not sealing because the door hinges sagging or needing re- shimmed. If the door gasket is ripped and ambient air is incoming, you will see it in the top of the freezer front areas (a clue). Is the evaporator fan turning at normal speed? Part # 5303918549. The freezer air duct plenum control should be at the middle point. Is the condenser coils clogged and boiling the freon? Use a condenser coil brush part #  to clean, along with a shop vac. When you turn the cold control up and back down, does it stop running the compressor at the middle position? I suspect not because of your given information. If it will not shut off, this part # is 5304421256. Lastly, there is a area in the bottom center of the defrost timer. Use a large flat blade screwdriver and rotate the dial. It has a lot of small cam steps that will quickly and very smoothly turn to the next click. Then there is a short "area" where it will stop the compressor from running and turn on the defrost circuit for approx. 25-minutes. Then it will time out of defrost and start compressor run time again. If you cycle past this quickly , you can go back and test again. When you are done, (after defrost completes)remember to start in the first run time step. If the "steps" are hard to click, it also will stick in run time only. So if the timer does not shut off during the manual test, it can be physically shorted needing replaced. Timer part # 215846602. Thank You.
Thermostat has been replaced. Frig temp was staying at 44-47 degrees only. Once changed went to 34 degrees. Just noticed 4 days after now temp went back to 44 degrees. No ice build up in freezer. Should we place defrost timer?
Answer Hello Maryann. Check and make sure the heater reads closed, and if so, you may have a bad defrost timer. Also check and see if the coils inside the freezer are frozen over. If so, it shows you still have a defrost problem. Hope this helps.
Will not defrost. I have replaced defrost heater and the unit still will not defrost.
Answer Hello Russell! Check the defrost timer 215846602 and the defrost thermostat 5303918202. You can test the parts using a multi meter TJMA-DM1. Here is a link from our free repair forum you can refer to for help with using a multi meter. Hope this helps, thanks! http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
