Chris for Model Number maytag model mtb1954dr I notice a popping sound coming from the unit on occasion, could this be a bad bi-metal switch? If so, where is the switch located? Also, how do I test the defrost timer?
Answer Hello Chris! Where is the popping noise coming from? You can test the defrost timer WP68233-3 with a multimeter MA-DM1. Here is a link from our free repair forum you can refer to for help with using a multi meter.
