If your pilot light is burning but the main burner won’t turn on, it usually means something in the ignition or safety system is preventing gas from reaching the burner. Common causes include:
1. Faulty Thermopile
What it does: Generates the electrical signal that tells the gas valve to open for the main burner.
Problem: If it’s weak, dirty, or failing, the gas valve won’t open.
Fix: Test and replace if needed.
2. Wall Switch or Remote Issues
What it does: Sends the “on” signal to your fireplace.
Problem: Loose wiring, worn switches, or a dead remote battery can break the circuit.
Fix: Check connections and replace batteries or switches.
3. Dirty Burner or Orifices
What it does: Allows gas to flow evenly to the burner.
Problem: Dust, rust, or spider webs can block gas flow.
Fix: Have a technician clean and inspect the burner.
4. Faulty Gas Valve
What it does: Controls gas flow to both the pilot and the main burner.
Problem: If the pilot works but the burner side fails, the valve may be faulty.
Fix: Replacement by a qualified gas technician.
5. Safety Sensor Issues
What it does: Monitors flame and heat for safe operation.
Problem: If it senses trouble (like poor ventilation or overheating), it will keep the burner off.
Fix: Technician inspection and reset after repairs.
Why You Should Call a Qualified Technician
Since gas is involved, diagnosing and fixing burner issues should be done by a professional. They’ll test the thermopile, wiring, and gas valve, then ensure the system is burning properly.
A small amount of light haze on your fireplace glass over time can be normal — but thick black soot is not and usually means something isn’t working correctly.
Common Causes of Black Soot on Fireplace Glass:
Why You Shouldn’t Ignore It:
What to Do:
Important: Soot buildup can be prevented with annual fireplace maintenance. During
service the technician will clean the glass, check burner settings, and ensure your
fireplace burns clean and safely.
1. Dirty or Partially Blocked Pilot Assembly
This is due to dust, spider webs, or soot can block the pilot flame, making it too small or
unstable. It prevents the flame from fully heat the thermocouple/thermopile, so the gas
valve shuts off. To fix this a qualified technician can clean the pilot assembly with a
special tool.
2. Weak Thermocouple or Thermopile
These parts generate the small electrical current that keeps the gas valve open. Over
time, they weaken or get dirty. As a result, the fireplace starts, but after a few minutes
the signal drops and the gas valve closes. A qualified technician can test the electrical
readings on these parts and replace them if necessary.
3. Overheating Safety Switch (High-Limit Switch)
If airflow is restricted (dust buildup, blower not running, blocked vents), heat builds up
inside the firebox. As a result, the safety switch shuts the unit off to prevent damage. A
qualified technician can inspect the vents, blower, and clearance spaces for blockages,
and then clean or repair as needed.
4. Faulty Gas Valve or Control Module
Electrical or mechanical failure inside the valve or control board can interrupt the gas
supply. As a result, the fire goes out even if sensors are working. A qualified technician
can take meter readings on the valve to determine if it is in the acceptable range, or
replace the valve, if necessary.
