The freezer that is located at the bottom of the refrigerator is not getting cold the digital numbers keeping jumping around and will not set back to the correct temp. What needs to be done to fix this problem?
Answer Hello Elmo. It sounds like the sealed system has failed and when the unit does not cool, the sensors are reading the actual temps in the unit. You will need an HVAC tech if the sealed system has failed.
Well, I changed the mother board after two weeks both freezer and fridge had to be manually defrosted again. What now?
Answer Hello Rod. Test and see if the heaters are bad in both evaporators. If so, you will need to have them replaced. However, it takes an HVAC tech to do a sealed system repair. You can test this with a multi-meter TJMA-DMT3.
