We have an older Heil furnace that stopped working last night. Went to try it this morning, click and nothing. Both fans work, husband changed transformer and is getting a capacitor right now..any other ideas?
Voltage meter time. Go through the safeties and controls untill you find where the circuit is failing to close. Test the hot surface ignitor, if it has one. Vents burried in a snow drift? Had a bunch of those calls this week.
