Trouble Symptoms

[SIZE=3]Micro-wave has stopped working. Power to the unit allows door light only. Digital display also is not working. I tried re-setting the unit by turning the power off than on after a 10 sec. wait.[/SIZE]
[SIZE=3] The fuse and the two thermal cutouts (normally closed) are OK. The Vent and Magnetron thermostats (normally open) are also OK.[/SIZE]

[SIZE=3]Previously the push button control performance was very erratic. Sometimes the right side would work better than the left side of the panel. Sometimes the button on the panel had to be pressed hard…then it would work. Sometimes I would hit the panel and it would be OK for a while. [/SIZE]
[SIZE=3]I suspect either the control panel or controller board. Please help.[/SIZE]
