Hello, if the power to the inducer comes and goes sporatically, and does it when you jumper the R terminal to the W terminal on the thermostats terminal strip inside the furnace, then... the problem is a bad printed circuit board,

.

If you would like up to 5 hours unlimited coaching on further diagnosis and repair, at no additional cost, its time to rate my input for the day, that gets me paid, locate the "finish and rate your expert" link near the top of the page and click on it. I will appreciate that very much.

I am in every day from 9 am to 11 pm west coast USA time to do any follow up, including coaching, training and repair advice as needed.
