Tuesday, March 8th, 2011

Question:

do all universal hot surface igniters fit in to the heater thing in the basements since i find cheap ones and wonder if it works on all of them so? reply soon

Answer:

Tough question, the answer? is no given the multitude of different furnace manufactures. The Honeywell Glowfly is a universal replacement ignitor that is designed to work on many different furnace applications. If you search Honeywell Glowfly application selection guide, under page 21 will list all the furnaces this ignitor will work on. Always remember, if you’re not comfortable or don’t know what you’re doing, call a licensed heating contractor . Thanks for your question; and good luck, Don.

Hot surface igniter education

The hot surface ignitor is a electrical component that is wildly used in most newer manufactured gas furnaces, like Bryant, Trane, Carrier, Rheem, and lennox just to name a few. Every time your furnace comes on the hot surface igniter is electrically energized with 120 volts and glows red hot for about thirty seconds igniting the gas at your furnace, similar to the way your kitchen counter top toaster works, when you push the lever down the element in the toaster turns red hot to toast your bread. Because your furnace may cycle on and off, up to four to six times per hour during the winter season, the hot surface igniter gets used a lot. Like the equivalent of you using your toaster 25,920 times in a six month period. Because it gets used so much the hot surface igniter is the only component of the gas furnace that needs to be replaced routinely, about every four to six years on average. There are two types of hot surface igniters that are used, the first one is a hot surface igniter made from material called silicon carbide, and this is the older style ignitor that should be handled with care because it is very fragile. The second newer type hot surface igniter is made from material called silicon nitride; this is a more durable material and is not as fragile as the silicon carbide, the more durable silicon nitride igniter will last longer, giving you sometime twice the life span. If your furnace has the old silicon carbide ignitor and you have a technician replacing it, you may want to ask about upgrading to a newer hot surface silicon nitride ignitor that may last longer.
