Newer homes in Las Vegas, NV include furnaces with electronic ignitors. These devices replace the pilot lights that were used in the previous generation of furnaces. Electronic ignitors offer enhanced energy efficiency because there’s no constant burning of gas. While these products are reliable, they can malfunction from time to time. Be aware of these signs that suggest your furnace’s electronic ignitor needs professional furnace service.

Furnace Won’t Turn On

The most common type of electronic ignitor is a hot-surface or controlled resistance filament. It works like a light bulb. Electricity flows through the filament, the filament gets hot and the heat ignites the gas. A broken or damaged filament won’t conduct electricity, so the furnace won’t be able to ignite the gas. You may hear the furnace click on, but it won’t be able to fully power up and perform a heating cycle.

Furnace Short-Cycling

Insufficient current or damage to the filament in an electronic ignitor may cause the furnace to turn on for a few seconds and then turn off. This is called short-cycling, explains the Department of Energy. The thermostat will trigger the furnace to turn on again within one or two minutes. This cycle will repeat over and over because the furnace will be unable to reach the temperature setting on the thermostat. Short cycling can also lead to a damaged capacitor, blower motor, and other furnace parts.

Thermostat Displays Error Codes

If you have a smart thermostat, its interface may show an error code when there’s a problem with the electronic ignitor. The owner’s manual or manufacturer’s website may explain what the error code means. However, it’s best to leave electronic ignition replacements to trained technicians. Any time you see an error code on your smart thermostat or its app, arrange for professional furnace service.
