Easy Repair Microwave Door Switch

These common micro switches are used in various appliances. Note that they come in three configurations, which can be distinguished by their terminal position and labeling: normally open (NO), normally closed (NC), and both. My microwave broke and only worked when the door was OPEN which is a major safety issue. Inside there is a plastic holder with 3 micro switches. After discharging the internal large capacitor with a grounded screwdriver, I tested the switches with an ohmmeter (you'll need to unplug some of the switch wires to get a good reading). I broke the retaining tab on the switch bracket, so to replace the switch I used a small plastic tie and wrapped it around the switch to secure it to the bracket. A few minutes of work and a $5 switch delivered in less than 24 hours saved me from spending $100 on a new microwave. .
