Vindobonau for Model Number RSD2000 My side-by-side Maytag was suffering typical symptoms of defrost cycle failure: refrigerator stopped cooling and then ultimately the freezer stopped freezing. I pulled the panel off the back, coils were frozen solid. I verified that the timer was advancing on its own. I pulled the thermostat and ohmed it in a glass of ice water. No continuity. So I purchased a new thermostat locally, because I wanted to get it fixed right away. I decided to ohm the new thermostat before attempting to install it and was dismayed to discover that it also shows no continuity no matter what temperature it's at. I can test it at room temp, float it in ice water, or freeze it solid in a cup of water. The ohm meter never budges, flickers, or otherwise shows any indication that it detects anything. It's a new digital ohm meter and it does detect continuity in other things (for example the metal serrated edge of an aluminum foil box). It's set to 200. Is there something I'm not understanding about what an ohm meter should show with a functioning defrost thermostat?? Is it really that likely that a brand new thermostat would be bad from the get go? I admit I'm not that savvy about electrical stuff, however I am usually quite mechanical/techie in other ways, so if anyone can at least verify I'm on the right track with troubleshooting this problem, I would really appreciate it. Thanks much!
Answer Hello Vindobonau. Set to 200 is ohms test, not continuity test. You need to read the manual sent with the meter and find the continuity beep test. When set to this, if closed, the meter will beep. Then use that test for the thermostat. Read More... Answered by AppliancePartsPros.com | Wednesday, June 5, 2013
