Hi. I'm Joe and I will be glad to help you out.
You probably blew a fuse. If you open the furnace, then remove the blower service panel, you will see a circuit board mounted on the blower housing.
The fuse will be plugged into this board.
It will be a blade type fuse, probably a 5 amp
Ok give me some time to take the blower panel off and look for a fuse.
Purple fuse with an E on it is open, (Infinite resistance when set to ohms)
ok. That's a 3 amp fuse. Do you have another to replace it?
I should have one in the car.
ok. Try that and see if that takes care of it
Found a 5 and a 2 so I went with the 5 amp. Furnace is working.
I will buy a 3 tomorrow.
5 Should be fine, but if the 3 was a factory install, better stick with that
