Thanks again I am calling it a night. Will let it soak over night and
continue tests in the morning. Does any one have the oscillator circuit. With
the connector on the bottom left to the right id something that looks like
an adjustment screw,flat round flush with the surface and a screwdriver slot.
Will not touch it unless I know what it is.
Thanks again Bert Kehren Miami

What happens to the current drain as the unit warms up? Does it fall off
after 5-10 minutes as expected? If not, it sounds like the oven controller
may be stuck on, overheating the crystal. I'd look into that possibility
sooner rather than later.
