Hi AppliancePartsPros, I am testing my magnetron and I know that the resistance across the two nodes should be small (0 < x < 1 Ohm), but can you tell specifically what the range should be? Should it be 0 Ohms?

Latest Questions

Hi. I have found three thermostats in my microwave with the following part numbers stamped on them ... 1. ksd-1201c 0 2. ksd-401c 70 3. ksd1601c 60 I check for conductivity on #2 and it is measuring an open circuit. The other two are measuring a short circuit. Should my #2 thermostat be measuring an open circuit? Because they all have a different part number, I assume they are all different, how are they different? Do they "open circuit" at different temperatures? Thanks, Luis

There are 4 thermostats on my microwave . 3 are original. One was replaced 2 months ago by a repairman. I jumpered the one out he replaced and it runs. Having trouble getting pn for the one I need. Its the one above and behind the fan. Not the one in the top of the oven1001 ksd-40lc 0 or either of the two side by side in the bottom panel 1003 ksd-40lc 70 or 1003. Ksd-120lc0 . I'm trying not to be confusing. Please help.

The microwave does not turn on at all, even though there is power to the outlet it is plugged into. A few years ago we had the same problem, I had to replace one of the thermostats/temperature switches behind the control panel (KSD-120LC, DE47-20034A). During the replacement, I found the plastic cover which encases the female electrical connector that connects to the male spade connector on the thermostat was burnt and deformed. I did not replace the connector, as I assumed the thermostat failed, which caused the heat that burnt the connector's plastic housing. Fast forward to today, and the same thermostat is bad, upon further inspection, the plastic electrical connector is even more burnt, and the spade connector on the thermostat is discolored and lose. The thermostat's continuity is intermittent. As I trace the wire, which has the burnt end, back through the harness, I discovered it is the feed directly from the electrical cord that plugs into the wall. This time I will replace the burnt connector with something similar, but why is the temperature able to get so high that this connector is heating up so much that it is burning? Is there something else I should look into replacing to prevent this from happening again? I'm not a big fan of there being a fire hazard in my home!!
