I have an Estate refridge model number as entered. The freezer works fine but the lower section will not go any lower than 50. Do you have any thoughts on what the most common problem would be. I think it would be a defrosting problem, but I have no idea where to start.

Latest Questions

Freezer works fine. Ice builds up on back and into the air chute and duct tower then refrigerator stops cooling. Seems that ice blocks the air flow to the refrigerator. Turn unit off and allow ice to melt and plug back in and every thing freezes and cools until the cycle repeats. Can you tell me what needs to be replaced?

Hi, My refrig had deforst system breakdown. One repairman replaced the heater and thermostat. It did not works and ice built up again in 3 weeks. Now I think defrost timer need to be replaced, it looks like a circuit board, I am wondering if I could test it before replacing it. Also how to access it? looks like just 2 screws holding the enclosure. Is the timer circuit board a plug and play? need any wire? Before I replace the defrost timer, Could I check the defrost heater and thermostat? Could I do it by checking continuity? Thanks!

Fridge works for about a week then gets warm for 2-4 days, still a little cold but not enough to keep food good, then gets cold again. Doesnt seem like fan is working when its warm. Freezer is working and blowing most of the time but one time last warm cycle it got warm and food started to melt. Thinking it's the defrost timer?
