have you tested the thermal cutoff's yet?

I bought it as a new inverter board but I can see on terminals is used ..yes its used inverter board..

that very well could be the problem. I would however like you to test the thermal cut off's first though just to make sure they are not the cause of this issue.

thermal cut off beside magnotron??if that one yes I did..

ok so then yes looks like that only leaves the replacement board being the problem and needing replaced.

this company although a little more expensive will let you return even an installed part if the part doesn't resolve your issue
