Signs Your Hot Surface Ignitor Has Failed
Most modern furnaces built in the last 20 years use a hot surface ignitor instead of a standing pilot light. It works exactly like a light bulb filament, heating up to over 2,500 degrees until it glows bright orange. If you look through the sight glass and don't see that glow before the gas kicks on, the part is likely cracked. This is a common furnace repair during the first North Texas cold snap.
You might hear the furnace blower motor start up and then hear a series of clicks. That clicking is the control board trying to engage the ignition sequence. After three failed attempts, the system will enter a lockout mode for safety. This prevents unburned gas from building up in the heat exchanger. It is a critical safety feature that requires a manual reset.
Diagnosis and Proper Part Selection
We do not just guess and swap parts based on a hunch. Every service call starts with a full electrical diagnostic to see if the control board is actually sending power to the ignitor. Sometimes the issue is a blown fuse or a faulty relay rather than the ignitor itself. We check the furnace flame sensor at the same time to make sure the unit stays lit once it fires up.
Not all ignitors are the same. A Goodman furnace might take a different voltage and wattage than a Rheem or a York unit. We carry heavy duty silicon nitride ignitors because they handle the vibration of the furnace blower motor better than the cheap ceramic versions. Using the wrong part can burn out your control board or cause intermittent furnace not heating repair issues later.
Why Heating Ignitors Fail in DFW Homes
Texas attics are brutal on HVAC components. The extreme heat during the summer causes the ceramic base of an ignitor to become brittle over time. When winter finally hits, the rapid expansion and contraction of the heating element causes microscopic cracks. Eventually, the circuit breaks and the ignitor goes dark. This is why many furnaces fail on the coldest night of the year.
Dust buildup is another major killer of heating components. If your air filters are not changed regularly, the furnace blower motor pulls fine particles across the hot ignitor. This debris acts as an insulator, causing the part to overheat and burn out prematurely. We check your ductwork and filtration during every ignitor swap to help you avoid a repeat failure.
