I had a similar issue recently. Ended up being a bad seal on the ice maker was allowing air to get in. Good luck, hopefully it ends up being an easy fix.We got any electricians here? My freezer already froze up again so trying to figure out what part is bad! The defrost heater it says online should read between 10-30ohms and mine was showing .030 on the meter i have so making sure i am not needing to do some math and move decimal places over or some shit and that this part is indeed testing bad! Pretty sure it needs replacing but wanted to make sure I wasn’t missing some step in the translation of the ohm test results!
