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.

Since we can't accurately diagnosis it over an internet connection, I'd
suggest getting a licensed, insured technician out there to look at it. Betcha it's a limit.... "Bob Kaplow" wrote in message ... This weekend I realized my furnace fan was running non-stop.

Bob , You just said to not buy any of these brands of hvac equipment for all are the same company now. Carrier Bryant Hiel Whirlpool Tempstar Arco Aire and a host of other brand names With this you can only buy 5 other brands out there Trane, Lennox, Goodman, Rheem, and York. Now the other may do better on this application. On your problem. I can't see it from here but it sounds like a Fan relay in the relay board stuck. You can hit it with a hammer to see. TURTLE |

I certainly don't reward companies who don't stand behind their products with repeat business. With this you can only buy 5 other brands out there Trane, Lennox, Goodman, Rheem, and York. Now the other may do better on this application. That looks like a sufficient list to pick from. Lennox was probably at the top of my list already. I've had zero problems with their central AC unit in the same 15 years. On your problem. I can't see it from here but it sounds like a Fan relay in the relay board stuck. You can hit it with a hammer to see. I'll give that a try. Bob Kaplow NAR # 18L TRA # "Impeach the TRA BoD" To reply, remove the TRABoD!

Bob , Awwwww Lennox is not on my list of HIGH quality stuff but if installed correctly. It will be good but it will not cover the trouble that comes with a poor installation. If you can try to pick from the other brands in your area maybe. Now if the installer is a real good one it would tend to be OK stuff. Just a Light warning here. TURTLE |
