Pressing the Clear/Pause button works. Sometimes. Most of the time, about a microsecond after pressing Clear/Pause, it goes right back to def1. Most of the time, pressing ANY button doesn't work. Usually takes me 10 to 20 tries to get anything to work. My microwave is about 3 months old. I will never buy Emerson again.
Is the cubic foot size of the microwave on the name plate?? It seems that with Emerson the size relates closely to the wattage .. 0.9 cu ft is 900 watts, 1.1 cu ft is 1000 watts .. 0.7 cu ft is 700watts .. That would be the closest info I can get.
Have 1 of 2 choices, the main fuse or the control board for the front switches and clock. primary of the small power transformer has opened. Unplug the unit and take case off and measure the fuse with an ohm meter. if u read 1 ohm or less then fuse is good. then measure across the main power plug tips. If read open then the power transformer is bad. Need to replace the board as not sure if transformer is available.
Hopefully it was not an unheated storage area!
Moisture and contamination can get into the controls from condensation due to big changes in air temperatures in areas like unheated storage units or garages.
That being said, the most common causes of a failure to heat are in order:
- bad door switches or door switch mounts
- loose connection at the magnetron
- problem with the control unit
- bad magnetron or other high voltage part
