Faulty hot surface igniter—another key component—can fail to ignite gas, prompting repeated ignition attempts. This increases gas buildup, heightening fire hazards. Similarly, a malfunctioning igniter may cause incomplete combustion, releasing toxic gases like carbon monoxide, which is odorless and lethal.
Thermocouple failures often stem from wear, corrosion, or misalignment. Over time, these issues compromise the system’s ability to detect flames accurately. Hot surface igniters, prone to cracking from thermal stress, may also fail to reach ignition temperatures.
Regular maintenance is vital. Inspect thermocouples for damage, ensure igniters are intact, and test gas valves. Homeowners should prioritize professional checks to prevent catastrophic failures. Ignoring these risks jeopardizes both property and lives. Stay vigilant—safe ovens save lives.
