Hi,

 

Do you have high voltage at the input of the transformer ?

 

Thanks

I am sorry that asking this one question without telling me what to do whether I have or don't have high voltage at the input of the transformer is not helpful.

 

I have found that the fan motor is bad and the fuze on the fan switch has blown.

 

Please do not charge me for the lack of help I received. Bill

Hi,

 

I am sorry that the back and forth discussion between me and the tech was not made clear for me. I assumed I had a one shot question and answer situation.

 

If I had known, I would have stayed with the tech.Thanks anyway.
