Question about Refrigerators
This unit is getting old at about 19 years. Recently, we had a power outage and after the power was restored, the lights no longer worked on the fridge side only. The freezer lights do work. Also the condenser fan motor is slow and not creating much (if any) airflow. Sometimes the fan does not operate at all when the compressor comes on. Both the fridge and the freezer appear to be cooling acceptably. All light bulbs and door activated light switches are not at fault as I have interchanged them with the freezer side and they all work on that side. 'Resetting the automatic light shut-off' by leaving door closed for 30 minutes (per the manual) does not reactivate fridge light. I suspect there is no power to the fridge light switch. Is this related to a worn-out fan motor, or any fan motor circuits? Would a bad fan motor be the cause of failure to reset the fridge light? What else could cause these problems at the same time?
First of all if you're condensor motor is controlled by electronic control board varyable speed type you might want to think about looking at replacing the control board. But first I would take a voltmeter test to see if the fan motor is getting enough voltage. If the voltage varies with the temperature inside the box then you have a controller. If the voltage remaind constant (120) and the motor still slows down yoy have a bad fan motor. As far as you're like the problem goes the only thing I can think of besides loose wires or bad switch.would be if it operated off the same control board.

SOURCE: SubZero 532 frig lights out
There are two door switches one for fan and the other for the lights. With the compressor running, there are two so yu need to make sure it is the refrigerator and not the freezer, open the door and press the right switch and listen for a fan. The left should be your light switch and the problem is generally in the switch, on rare occasions there is a failure of bi-metal safety switch part number 4200850. One very rare occasions you may have a wiring proble.If you go to www.subzero.com there is a showroom locator tab on the top right corner, click it and you will go to a locator page which will get you to your local parts didtributor.

your problem on this is the main control in the compressor compartment. unplug your refrig then remove this control unplug all connectors and reconnect. this will probably get you working temporarily In almost every case I've seen we ended up replacing the control board. thx peyton

SOURCE: During a recent thunder storm,
The bulb is controlled by light switch only.
The switch is bad or there is loose connection on the light switch.replace the left light switch with Sub Zero Part # 3060140.Remove the light switch out and then properly reconnect the wires to their respective position and recheck if still same problem then it has to be replaced.
