Question about Whirlpool MH7140XF Microwave Oven
I burnt a bag of popcorn in the microwave last week. It worked all week and today it will not heat anything. It seems like it is working but nothing heats. If I use the sensor buttons like "popcorn" it stops and say F3H.
Thanks for help.
Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.
I recommend checking all these area that are located inside the microwave for faults.
The most common issue will be a failed Magnetron.
The diode and, fuse will be located on the noise filter assembly.
