We are having a problem with the refrigerator freezing everything. the temperature is set at 40F. I have recently cleaned the motor and fan for the frig, but it is still freezing the produce drawers and now in the back there is ice forming. How do I fix this problem? Thank you for your anticipated help!

Re: sub zero 632 s frig freezing everything
First, is the temp really 40?? Get your outside thermometer and stick it in there. You may get a surprise. If so, see if the thermostat will respond to any changes. It is possible that either the sensor or the electronics have gone bad...I'd vote for the sensor.
the other possibility might be low gas...but I'll want to see what the temp in the unit is and whether the changes you make do anything.

The sub zeros I have worked on have a compressor for each side. Is your fan blowing. You may have a defrost timer or heater. Possible low on gas but thats not very likely the sub zeros are made very well. Check to see if fan is blowing. Check condensor coils on top to see if they are clean. Check to see if your condensor fan is blowing. These are just possoble problem you can check if every thing looks good. Call a service tech ask for free estimate on repairs. Rus
Hello. You need a new cabinet thermistor and while you are at it replace the evaporator thermistor. (The evaporator is the cooling coil behind the back wall of your fresh food section) . These sense the temperature in your frig. Both of them are behind the back wall of your fresh food compartment. You will need a wire crimper and a heat gun or lighter to heat shrink the wire connectors that come with the new ones.
Just posted this elsewhere and it sounds like the same problem:
As you probably know, the recommended temperature range is between 35-45 F so if your control will not allow you to set this, the sensor or associated regulator has failed. This seems to be an issue with Sub-Zero.
