David S. for Model Number FRT21G2NW9 Freezer too warm (20-22 deg), and Fridge too warm (42-46 deg) -- even with Cold Control knob fully clockwise. Replaced Run Capacitor. Also, have new Defrost Timer to try tomorrow if Run Capacitor affects no change. Is there a fine adjustment screw on Cold Control I should try? Or is a new Cold Control the next step? Or... should I check Evaporator Coils in the freezer? (FYI: Evaporator Fan is blowing cold air -- albeit not cold enough. And there is no noticeable ice in the rear of freezer. Also... Condenser Fan appears clean, intact and running well, as do Condenser Coils.) .
Answer David, no there is no longer "a fine adjustment screw on Cold Control" the manufacturers eliminated that adjustment tool several years ago. We don't "see" replacing the defrost timer as a remedy to the situation, it sounds more like an airflow problem or a sealed system issue, based on your description and information. Remove the evaporator cover and check the evaporator coils for an even and complete frost pattern on the complete evaporator (front to back and top to bottom) if there are uneven, less or no frost in areas of the evaporator, this would indicate a sealed system issue or inefficient compressor. If all's OK, then consider the cold control. Read More... Answered by AppliancePartsPros.com | Thursday, March 5, 2020
