My furnace is acting up - It's a Carrier - not sure what model but that shouldn't matter - I think they're all the same with regard to the safety switch -
The problem is, sometimes the furnace just stops working & doesn't kick on until I go down and remove the lower panel & then put it back in place. So I've got to assume that the switch is a breaker? (It cuts out about every 5 days.)
Any ideas on how I can diagnose what's wrong before calling for service?
