I have a older Siegler free standing gas heater.  I recently took it all apart, cleaned burner, fixed broken front glass, heat synks and put it all back together.  Fired up and it works great. I had NW Natural come out to inspect it for safety.  Now I notice that the fan won't shut off after the gas heater has been turned off and totally cooled down. Got any idea how to fix this?  Thanks, Chuck

Chuck,yes after you put it back together the fire startedthen heated up the box then the fan came on in that order. And when it shut down the gas the fan just never did shut off. then it's probably what's called the fan switch.I believe the one for that old guy is if you go to the front of the furnace ground level that great comes off lifts of the front.I believe the switch is behind that it's going to be around snap disc with two wires I don't think it's all about it but you need to have that heater unplugged. if you go online with the model and serial number you should be able to find the parts break down list. Sorry but I can't do much better I've only seen two of those my whole career like 30 years

I am in Portland Oregon at Ben's heating 503-233-1779. I work days, so I can only answer early in the day or later in the evening. I only answer public questions for residential equipment. I am very well versed in gas, electric and heat pumps and will only answer residential applications. I have been known the past decade or so, by my employers as the guy you send when no one can figure it out. Trouble shooting is my special. I understand the physics behind air flow, refrigerants and electricity. I understand programmable t-stats, zone controls, economizers, fossil fuel kits and the engineering thought process in the wiring and construction of residential equipment


I was lucky enough to start in this field almost 30 years ago as an installer, for a company that installed the best duct systems I have ever seen, even to this day. The best ,as far as understanding the way air really flows through a duct system, from the return air to the very last supply register . They also had great pride and the duct work was put in, not only to last 50 years, but to look exceptional. Then as I started doing service work, I was again fortunate that I found a 3 year engineering class being put on be a man that was the educational director for the Entire united states for a society called " the Refrigeration Service Engineering Society " And for the next 3 years I schooled at night and practiced what I learned during the day, a great advantage over schooling and then trying to remember it years later.. Versed in duct design manual J heat gain/loss calculations.

Refrigeration Service Engineer's Society

I have 2 inventions that have gone through the process and been recorded at the National Institute of Standards and Technology from start to finish and thus been invited to national innovation workshops by the dept. of Commerce and the dept. of Energy. They are waste heat recovery devices that N.I.S.T approved as valid and am currently looking for marketing partners to get this product into the hands of consumers and make a BIG difference in Energy savings for every Household and Eatery and take a big bite in the the peak hours power consumption that face our Utilities companies.
