Troubleshooting Heat & Glo® Fireplace Blinking Red Light

Heat and Glo fireplaces are popular for their efficiency and aesthetic appeal. However, like any appliance, they can encounter issues. One common problem is the blinking red light on the fireplace, which can be alarming if you don’t know what it means.

Troubleshooting this issue is crucial to ensure your fireplace operates safely and efficiently.

What Does the Blinking Red Light Mean on Heat & Glo® Fireplace?

The blinking red light on your Heat and Glo fireplace serves as an indicator that something isn’t functioning correctly. This signal is designed to alert you to potential problems that need attention.

Common causes include issues with the pilot light, gas supply, thermocouple, thermopile, ignition control module, or ventilation.

Heat & Glo® Read Light Troubleshooting Steps

Before diving into complex fixes, start with some basic troubleshooting:

1. Check the fireplace for any visible signs of damage or obstructions.
2. Turn off the fireplace, wait a few minutes, and then turn it back on.
3. Ensure the thermostat is set to the desired temperature.

1) Inspect the Pilot Light

The pilot light is essential for igniting the gas in the fireplace. To ensure it’s functioning properly:

1. Refer to your fireplace manual for the exact location.
2. The flame should be blue and steady. If it’s yellow or flickering, there may be an issue with the gas supply or the pilot itself.

2) Gas Supply Issues

A faulty gas supply can prevent your fireplace from operating correctly. Here’s how to check it:

1. Ensure the gas valve is open and there are no blockages.
2. Check the gas line for any leaks or issues that might impede the flow.

3) Thermocouple and Thermopile

These components are crucial for detecting the presence of the pilot flame and generating the necessary voltage to keep the gas valve open.

1. If it’s malfunctioning, the gas valve won’t stay open. Test it with a multimeter and replace if necessary.
2. Similar to the thermocouple but generates more voltage. Test and replace if it’s faulty.

4) Ignition Control Module

The ignition control module regulates the ignition process. A faulty module can prevent the fireplace from lighting.

1. Signs of Faulty Module: No spark or repeated ignition failure.
2. Replacing the Module: Follow the manufacturer’s instructions for replacement.

5) Ventilation Problems

Proper ventilation is vital for the safe operation of your fireplace.

1. Inspect the Vents: Check for any blockages or obstructions.
2. Clear the Vents: Remove any debris or buildup that could hinder airflow.

6) Error Codes and Their Meanings

Heat and Glo fireplaces often display error codes to help diagnose issues. Common error codes include:

1. Code 11: Ignition failure.
2. Code 12: Flame lost after ignition.
3. Code 13: Low voltage at the control module.
