Kitchen-Aid SxS Refrig
Ser# SL4053047 (Oct.2001)
Need to know if these are all symptoms of a bad main control board, (looks almost exactly like the Jazz Board in the Maytag that been being talked about how to remove control console).
Problem was refrig section warm, found evaporator plugged with ice. Checked defrost terminator and heater all OK didn't know how to put into defrost at first visit, (techsheet was missing). Defrosted the evaporator and came back the next day with tech info and put into defrost manually with diagnostic test mode.
Defrost came on but did not turn off after 5 minutes and start the pulsed operation-off 60 seconds off and 120 seconds on for 25 minutes or until defrost terminator opens. Defrost heater stayed on continuously for 17 minutes then shut down only when the defrost terminator opened.
Also the refrig temp setting seems to be changing by itself, after plugging back in and turning on setting controls at 0 freezer & 35 refrig it would start up running and run for maybe 2 or 3 minutes then you would hear the fans all shut down and compressor all shut down like a power failure but temp displays didn't shut off but refrig temp changes to 34 and it restarts. I've actually seen it do this 3 or 4 times while I was there each time just after a restart after being unplugged or just shut off by the power button.
Is the no defrost in normal operation but working OK when initiated thru diagnostic classic symptoms of a bad Jazz style controller board?
