Thermal fuse MW8102SS Emerson microwave

If the 20A fuse is blowing, it is often the high voltage transformer or magnetron. If this is the case, and the microwave is not under warranty, replace it. Residential microwaves are generally considered disposable. Parts and labor are just too expensive. A magntron or transformer can cost more that half the cost of a new microwave.

most micros have either a 15amp or 20 amp ceramic fuse at the top behind the touch pad. cover has to be removed. don't touch the hv capacitor. check fuse for continuity if none replace with like fuse. if it blows again you have another problem.

Normally when you take the cover off, the fuse will be on the right of the oven on the circuit board.

Call any service center that services appliances or most any electronics parts supplier. You will have to know the specs of the thermo fuse to order one.

If the thermo fuse is blown, most likely there was an overheating condition, and there is a failure somewhere. This can be a serious safety issue. When you change the fuse, it may blow again. It would be best to verify the specifications and for proper operation of the unit before using it again. A qualified service center for microwave ovens can do this for you.
