Correct, I could only find off-board mount for that Va & voltage.
I f you go that route, I can show the connections on to the board.

Looking at the board again, I see that MOV1 appears to have a burn mark below it?
If this is shot, it looks like the board may have had a power surge and the reason for the fried transformer.

Yea thats what i mentioned in one of the forst posts. Grandparents had a power surge and fried the transformer. So you think there could be mire damage to the board? I thought the transformer was designed to blow. The transformer is burned.

MOVs are designed to or attempt to suppress surges, if the surge is large enough, they commit suicide in the attempt! :oops:
It will be difficult to tell until power is restored to the board, whether any other damage has occured.

May be time to just trash the PCB and replace it.

It is either that, or replace the MOV and transformer and see what else shows signs of failure, if anything?
If you had a 12v supply, mains or battery, you could sub the transformer supply and power it up and see.

Different places online. I have the board number. Its a treadmill motor control board. They still sell direct replacements for the entire PCB.

texas. P/P? I believe there is a 50-60$ refundable core charge on that too, which is no big deal.
i believe it was 199$ new, with free shipping.
