My compressor will come on work but deforst heater will not work. I replaced heater but my coil still freez & heater will not work. Help////
Answer Hello William. 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
My freezer fan does not work nor defrost heater.also if the control board is bad will the compressor come on. My compressor come on but no fan or defrost ????
Answer Hello William,
The defrost heater will only come on when unit goes to defrost mode. You can check the fan motor by testing for 120vac, when the unit is running, across the leads. If you have 120vac then you have a bad fan motor. The most likely cause for both the fan and the heater to not work would be the Adaptive defrost control 5303918476. Check continuity on your heater as well to ensure that it is good. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
My fridge works fine for four or five days, then it stops circulating the air. ice trays on the bottom of the freezer are still ice, but ice trays on the top shelves are water. The fridge side gets fairly warm. the kicker.... I give the side of my fridge one solid thump and it kicks on and works fine for another four or five days. I dont know if its the condenser fan or something that controls it that likes to be thumped.
Answer Hi Kyle. When the unit runs, look at the freezer and see if the evaporator fan motor is running with the compressor always. Also, make sure the condenser fan motor is running as well at the same time. Is the center divider wall in between the freezer and fresh food door too warm to touch? If it is too hot, then you need to remove the back and use a condenser cleaning brush part # TJ103 along with a shop vac to clean the condenser coils. This will lead to a no-cool, and also back up and overheat the freon inside the compressor. The compressor should be almost too warm to touch but not hot enough to fry an egg on it. The condenser fan motor is part # 5304448483 if needed. Clean the cond. Fan blade completely. Are the interior lights on? Your unit has 3-controls. 2 manual and one electronic defrost control board. While it is running, do you see a frost build up inside the lower back wall of the freezer ? If so then you have a defrost issue. Consider the defrost thermostat part # 5303918214 and the defrost control board part # 5303918476. The defrost control board is behind the upper rear lt corner area . Do you have to lightly tap it there to activate a relay to contact again ? But as you say the usual given thump tells me that it is more of an issue of the manual control not making the commanded run time. Use a volt/ohm meter part #@ TJMA-DM1 to assist you in your diagnostics. Use the meter to test with the ohm scale if the freezer thermostat part # 5304421067 or the fresh food thermostat part # 241586503 has failed. You can rotate the controls from low,medium and high contacts to see where the open is at inside the switch. The resistance should read 0-ohms in all settings. You should normally feel a "detent - step" as the capillary tube senses the surrounding air and will show as a open at this detent. If there is a open or no meter reading then the switch being tested is bad. This is a tricky one because you have to take it one step at a time. Do you hear a loud audible click every 30 seconds or better coming from the back of the units compressor relay part # 241527803? Do you have a loose wire at the controls , door switch or the compressor relay ? If you remove the compressor relay, it should read 5-6 ohms cold. If it rattles then change it. Let me know how to help further. Thank You.
