Furnace blower won't stop running
This weekend I realized my furnace fan was running non-stop. My first
thought was that we'd left the blower switch on, as we frequently do to keep air circulating in the house. But the blower switch was off, and even turning the HEAT/AC switch to OFF still left the blower running. Is my thermostat finally toast? Is there a relay somewhere on the furnace that controls the blower that might be stuck? Or is it the electronic furnace control module? Or something else. How do I tell what is bad? The thermostat is a programmable White 5/2 day 4 setting electronic. The furnace is a Heil/Tempstar 100K BTU upright condensation furnace, about 15 years old. This fall the blower was replaced after it died. NOTE: I would recommend everyone *** AVOID *** Heil Tempstar like the plague. The stainless steel heat exchanger rusted out prematurely, about 3-5 years IIRC. It was repaired by a local service person, but he told me there had been a safety recall on this unit. No notice was ever sent out in spite of having "registered" the warranty. When I contacted the manufacturer, they confirmed the recall, but wouldn't pay for the repairs. They had a "secret" recall that had "expired" before mine finally failed. It seems they would rather kill their unsuspecting customers than have to pay for warranty repairs. There have been at least 2 other design defect failures that I've ahd to eat since then. This is *** NOT *** a company you want to do business with.
