Gerald A Nipomo , CA April 22, 2017 Appliance: Maytag Microwave JMV9196CB1 Maytag Microwave Jmv9196cb1: Bad activation switch. How to replace Microwave Door Switch. I removed the face pans behind the door & accessed the switches & replaced them after watching a u tube video. All the switche are different so you have to make sure that the switches match up with the mfrs diagram. The repair was easy once you figure out what has to be done. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
