Before diving into specific troubleshooting steps, it’s helpful to understand the common issues that can affect your Heat & Glo fireplace. These often include problems with ignition, pilot light malfunction, gas supply issues, venting problems, and sensor failures. Recognizing these issues can save you time and frustration during the troubleshooting process.

Ignition Problems: When Your Fireplace Won’t Light

A common issue is when your Heat & Glo fireplace fails to ignite. This can be due to several factors, often relating to the pilot light, the igniter, or the gas supply.

Checking the Pilot Light

The pilot light is a small, constant flame that ignites the main burner. If the pilot light is out, the fireplace won’t light. Check if the pilot light is lit. If it’s not, follow these steps:

Locate the gas control valve, usually near the base of the fireplace.
Turn the gas control valve to the “Pilot” position.
Press and hold the pilot button while using a long lighter or match to ignite the pilot light.
Continue holding the pilot button for about 30 seconds to allow the thermocouple to heat up.
Release the pilot button. If the pilot light stays lit, turn the gas control valve to the “On” position. If the pilot light goes out, repeat steps 3 and 4, ensuring you hold the button long enough. A dirty or failing thermocouple is often to blame if this process fails repeatedly.

Examining the Igniter

If the pilot light is working but the main burner won’t ignite, the igniter may be faulty. The igniter is responsible for creating the spark that lights the gas.

Visually inspect the igniter for any damage, such as cracks or breaks.
Listen for a clicking sound when you attempt to ignite the fireplace. If you don’t hear a clicking sound, the igniter may need to be replaced.
Check the igniter’s wiring connections to ensure they are secure.
