Frequently Asked Questions
•What type of refrigerant does my Sub-Zero use?
Sub-Zero refrigerators typically use R-134a or R-600a refrigerant. Check the unit's model number and refer to the service manual or the data plate on the compressor for the specific type.
•How do I test the compressor relay and start capacitor?
Disconnect power. Use a multimeter to check the relay coil for continuity. Also, test the relay contacts for continuity when the coil is energized (apply appropriate voltage to the coil). For the capacitor, discharge it safely and then check its capacitance using a multimeter with a capacitance function. Compare the reading to the capacitor's rated value.
•Where can I find the service manual for my Sub-Zero refrigerator?
You can often find service manuals online by searching for your specific model number followed by "service manual." Authorized Sub-Zero service providers also have access to service documentation. Some manufacturers require registration to access the manual.
