Bill for Model Number JS42CSDBDA My freezer section temperature fluctuates from 0 degrees to as high as 15-16 degrees. I assume it is going through defrost cycles but I haven't noticed this until recently. I have had the compressor replaced (twice) and the last tech told me that Whirlpool said that the temperature fluctuations were normal. there are times when it takes six to eight hours for the temp to return to the setting (0 degrees). Have also replaced the damper. Is it normal for the freezer temperature to fluctuate all the time. If not, any ideas what might be going on?
Answer Bill, Everything you've mentioned or commented on is pretty much normal. Yes the freezer temperature fluctuates constantly, The control checks for a specific resistance for a specific amount of time, in order to average and maintain temperature in the freezer. During a defrost cycle, the temperatures can get a bit high( yours are in range) but it usually takes a couple of hours to return to the designated temp. You may want to conduct the "diagnostic service test mode" and considwer the Evaporator Motor 12002054 could occasionally get stuck and run at a slow speed. or the compressor control board 12002799 It could also have a fault, and could cause the compressor to run in a slow mode as well. Your Tech data sheet is locateed up inside the compressor compartment, you can conduct the diagnostic tests whenever you can or wish, just remeber to return it back in the compartment. Read More...
