JE740WY010 General Electric Microwave - Instructions

Removed cover. Found oven flame thermal cutout and measured across the terminals with an ohmmeter. Found no continuity. Thermal cutout wasn't allowing a complete path for input line. Ordered the oven cutout and 2 days later I installed the new part, re-assembled the oven cover and Voila! Fixed. Simple repair saved my friend from having to purchase a new microwave.

Opened the microwave oven door, unscrewed two screws which held the control panel on, then I removed two of the door switches (each had two screws), and then used the continuity tester to see which one was not operating. It turned out to be the secondary door switch, replaced it and to my amazement, the microwave worked. I have never repaired an appliance before but I didn't want to replace our over-the-stove built in microwave. It was the best day ever when it was working again! The hardest part was getting myself to try the repair.

Watched How to repair a Microwave that turns on when the door is opened Video on the web. From this took a shot at the switch was the problem. When I removed the switch it was defective. The small button was in and when you turned the switch upside down the button would drop back into position. Ordered a switch for $25.oo , installed it and the microwave is working fine.

it was a simple screw in on both ends. no soldering

Remove the back cover screws and remove back/top. Locate the thermostat and remove the two Phillip screws. Cut off old scorched terminals and replace with new terminal connectors on the wire ends and install new thermostat and reassemble.
