I assume the Main control is bad as I didn't see any other componet on the wiring diagram
that affects that operation
Just wanted to know if there is some operation of the main control that I'm not aware of
that could cause this condition

I did not make a copy of the electrical diagrams. I usually take a picture with my phone to keep with me, but I forgot.
model# 650 S serial#1717118
Original call was for a ripped ff door gasket and temperture in freezer too cold
When I arrived the next day the freezer temp was -1* and set at 0*. ordered the gasket and when I returned in 5 days the freezer was at -21*
unfortunately for me I order the wrong gasket. I turned the house power to the unit off to maybe reset the control.
When I came back they told me the temp was between -13*and -21*. I turned the unit off at the control panel and everything seemed to turn off
normally All the lights and fans seemed to shut off. when I opened the freezer door I thought I heard the freezer evap fan stop.
sure enough it was working with the unit off. (on/off with the basket switch)Then I checked and the freezer compressor was also running.
when I turn the unit back on all the functions are normal. lights, compressor,fans all come back on. turn it off and freezer compressor/evap fan
stay on. I didn't check thermistors believing that if unit is off nothing should be running. no error codes and the freezer did not go into defrost when i turneed back on
However it appears that it is defrosting. Normal frost build up on evaporator.
