Frequently Asked Questions
•How do I test the defrost heater element with a multimeter?
Set your multimeter to the ohms setting. Place the probes on each terminal of the defrost heater. A reading close to zero ohms, or some low value, indicates continuity and a good heater. A reading of OL (open loop) indicates a faulty heater.
•Where is the defrost drain located and how do I access it?
The defrost drain is typically located at the bottom of the evaporator coil, behind the rear panel inside the freezer. You may need to remove the evaporator cover to access it. The drain usually empties into a pan located near the compressor.
•What if the defrost system seems to be working, but the ice buildup still occurs?
Check the door seals for air leaks. Run a dollar bill around the door seal with the door closed. If you can easily pull the bill out, the seal is likely leaking. Also check the door hinges for proper alignment. A misaligned door can also cause air leaks and ice buildup.
