Furnace Igniters Cause Problems On Homeowners' Units
Newer Models Also Effected

UPDATED: 1:34 pm CST January 21, 2005

AMES, Iowa -- Homeowners with energy-efficient furnaces may want to watch for igniter problems, one specialist pointed out Thursday.

Joyce Thies, an Ames resident, said she returned home from a vacation in California to find her home in shambles. Her ceiling was falling because her water pipes burst, and water was everywhere.

Thies said she left her heat on to keep the water pipes warm while she was gone, but she said the furnace's hot surface igniter quit working. She said this was not the first time that the ignitor broke.

Matt Converse, of Converse Conditioned Air in Ames and furnace expert, said to NewsChannel 8 igniter's failure is a common problem. He said the hot surface igniter replaces the pilot light system. He said the ignitor is more efficient and easier to take care of. But he added that some igniters are unpredictable and can fail at any time.

Converse Conditioned Air did not install the furnace or do maintenance on the furnace in Thies' home.

Converse said that with furnaces that are between four and seven years will start going through igniters. He suggested that if homeowners are going to be away in the winter that they make sure someone is checking on the furnace. He said that the igniter issue is the first thing the homeowners know if they are buying energy-efficient furnaces.

Converse said he would still recommend high-efficiency furnaces with these hot surface igniters, and he said the igniters are safer than pilot lights.

Thies rebuilt her house -- adding new cabinets, appliances and a bathroom. She has homeowner's insurance, but it will not cover all the damage. She said she checks her furnace twice per day to make sure it's running that that will not fail her again.

The flame sensors used in these 'hot-surface ignitors' are really sensitive little devices. They actually conduct an extremely small voltage right through the ignition flame to detect if it's O.K. to open the gas supply to the main burner. Anything which keeps the flame sensor from conducting properly, i.e. surface oxidation, will keep the furnace from lighting.

A simple cleaning with a fine Scotchbrite pad and an alcohol pad will restore the proper function about 95% of the time. Interestingly enough, if your laundry is in the basement near the furnace, these flame sensors will act up much more frequently. The fumes from the scents added to detergents and fabric softeners will quickly oxidize the flame sensor's surface.

Before I was told this by a sympathetic HVAC repairman, I had a couple of furnace failures, and replaced two of the flame sensors (at $37.00 apiece for just the part). I now clean mine about once a month; it takes no more than five minutes. I've had no more failures since starting this routine.

Do you happen to live in Iowa? I would like to find that sympathetic repairman because I am having the same igniter problems.
