Frequently Asked Questions
•How do I access the condenser coils for cleaning on my Sub-Zero model?
The condenser coils are typically located at the bottom front or rear of the unit, behind a removable grill. Some models require a 1/4-inch nut driver to remove the grill. Consult your owner's manual for specific instructions for your model.
•What type of replacement rubber grommets should I use for my Sub-Zero compressor?
Use only genuine Sub-Zero replacement grommets. Aftermarket grommets may not provide the proper vibration dampening and could lead to premature compressor failure. Check your model number to ensure compatibility.
•How do I test the defrost heater on my Sub-Zero refrigerator?
First, unplug the refrigerator. Locate the defrost heater, usually behind the evaporator panel. Use a multimeter to check for continuity across the heater terminals. If there is no continuity, the heater is likely faulty and needs to be replaced. You should also check the defrost thermostat for proper function.
