Furnace Ignitor Resistance at Ronald Alvarez blog

Furnace Ignitor Resistance. If it’s ok, call a furnace repair/heating & cooling company. Hopefully, your furnace will fire after installing a new ignitor, and you’ll soon be warm again. Your furnace might blow cold air, have shorter than normal cycles, won’t have a glow, or your furnace won’t start at all. Fortunately, it’s easy to test the furnace ignitor. Sometimes, the hsi will not heat up at all, leaving your furnace unable to ignite its gas burners. If the meter display shows a higher result than 400 ohms of resistance, it’s likely the igniter has weakened; When it stops running, there are a few signs to look for. A fully negative continuity result will mean the part has failed completely. Repeated clicking in small intervals usually means your igniter is not coming on and working. You will also hear a clicking noise that is a sign your heater system is trying to come on. Some common symptoms of a failing hot surface ignitor include delayed ignition or a furnace that takes too long to turn on or shuts off prematurely. If it’s bad, buy a new one and install it. The ignitor plays an integral role in providing warm air to your home. Look under your furnace and see if your igniter glows when your furnace tries to start up. All you need is a multimeter to measure the voltage or resistance (or both).

Pull the ignitor, and check whether it is getting power or test it directly to check resistance.
