Mike for Model Number JUC2450ARS

Everything in frig froze (think b/c the door was left open a crack). Once we thawed frig, cleaned it, and turned thermostat back to #4, everything froze again. We repeated above steps, but tried lowest and highest thermostat settings (1 & 7 - just to be sure that we weren't getting them confused as to highest & lowest) and everything froze each time. Today I repeated above steps but pulled frig out, cleaned condenser coils and all area around, plugged back in, set thermostat to #4 position and am giving it 48 hrs. to re-set itself with nothing in it (this is what the manual says to do). Any ideas-other than the thermostat sensor not working? Thanks so much!

Answer

Mike, You're on track, Now that everything is cleaned up and the door is closed and sealing all the way around, and the compartments are empty, you want to use an accurate thermometer in a cup of water and check for a temperature in the mid 30 dgr. range(38 to 40 dgrs. reccomended) after the 48 hour run time. If any adjustments are made you need to wait 24 hours, before doing another adjustment. If the problem persists, then replace the control. Thanks and Good Luck
