Hi. It sounds like your unit is not self defrosting, if you had heavy frost across the evaporator. This blocks your air flow to the refrigerator section. If your heater and bi metal test good, the only thing left in the defrost system would be the main control board. p# 241739711. This is exactly how I would diagnose a bad control board. By process of elimination. This unit does not appear to have a separate defrost control . Once you defrosted the evaporator, it could take up to 24 hours to reach normal temps again, and will work properly until the frost builds back up again, which usually takes about 5-7 days. If you were getting an uneven frost pattern or an ice ball, this would not be a defrost issue and would indicate a sealed system issue. Most likely a leak. Attached is the tech sheet for your unit.
