Refrigerator and freezer quit cooling and I unplugged for several hours and plugged unit back in and refrigerator and freezer started working for approx. a day and I repeated this step unplugging and it did the same. Where do I start looking for the problem?

My refrigerator randomly will cycle on and off every second. It will keep doing this until I turn the thermostat off and let the relay on the defrost board click on and off about 3 times and then can reset thermostat to original setting. Would this be the defrost board or a sensor?

Our refrigerator does not work. However, when refrigerator is plugged in, all the lights work but fan and refrigerator does not run. What could be the problem? I am thinking it could be something wrong with adaptive electric board timer or cold control. How should I test the adaptive electric board with DMM using continuity? There are six pins on electric board. Which one should I connect to each other to confirm either its working or not? Thanks

Latest Questions

Dear sir To test the defrost eletronic control, may I disconnect the plate and run trhe refrigerator? In negative case, how is the correct procedure to test it.? I am asking this, because when I start the refrigerator, after a 3 or 4 seconds, the compressor cut off, and I tested the relays and the compressor and both are good.

Manual defrost activation did not seem to power heater till third time I got board to click. I replaced the Board in a Whirlpool Refrigerator top freezer model. Freezer coils were blocked and when I opened the panel the fan was working, so I defrosted freezer and replaced the board. Two days later, has a clicking sound seeming to come from inside fridge control panel and fan speeding and slowing in unison for a few minutes relayed from owner a couple times a day after and frosting again. Middle of evaporator normal frost pattern with heavy concentration of frost bottom 1/3 of coil blocking inlet in freezer and sides and on top of evaporator with a pile of frost in the middle reaching toward fan. Some frost also in drain hole.
