A furnace whose pilot light won’t stay lit is a frustrating problem in Whitesburg, KY. Maybe the pilot light ignites but fizzles out and won’t stay lit no matter what you try. Read on and find out the hidden causes behind your furnace’s pilot light repeatedly going out and what steps you can take to rectify the situation.
Bad Thermocouple
This is the copper rod that your pilot light hits directly, and it’s an important safety mechanism. It’s designed to shut off the flow of gas should the pilot light go out so the gas doesn’t flow into your home. Problems occur when the thermocouple is dirty and covered in soot or when it needs replacing.
Faulty Thermostat
First, make sure your thermostat is set to heat and the fan is either switched to on or auto. If all this is the case and your pilot light still won’t ignite, check your thermostat for an error code.
Dirty Pilot Orifice
When your pilot light orifice is dirty, a weaker, yellow flame exists instead of a strong and steady blue one. This weaker flame may have trouble hitting the thermocouple, making the system shut down.
Dirty Filters or Vents
Sometimes, a pilot light that won’t stay lit is due to restricted airflow in your HVAC system. Dirty, clogged filters and vents are a common cause of poor airflow that is easily fixed during furnace maintenance.
Faulty Gas Regulator
The gas regulator is a part attached to your gas meter outside and controls the flow of natural gas into your home. Pilot light problems in several appliances indicate a problem that warrants an immediate call to your utility company.
