I have installed a new draft fan and thermostat on my furnace but when I turn up the thermostat to cut in the draft fan nothing happens. Everything else still works fine. I have tried another relay but still nothing. I have tested the wires and it seems to me that the power goes into the transformer but does not come out. How can I get my furnace fixed?

If you have 120 volt into transformer, but no 24v out of trans, you need a new transformer, or possibly a new fuse on the low voltage side of trans.

No problem. Was it a bad transformer?
