Gas Fireplace Repair

 Gas fireplace Repair  possible Problems

Thermocouple

The thermocouple is a small but essential component responsible for sending a signal to the gas control valve.
When the pilot flame touches the upper section of the thermocouple, heat generates a very small voltage.
That voltage travels through the thermocouple body to the gas control valve, confirming the presence of flame and allowing gas to continue flowing through the internal safety mechanism — keeping the pilot light on.

Over time, the upper part of the thermocouple gets burnt or weakened and stops sending enough voltage. When that happens, it must be replaced.

Our certified gas technicians always carry a full range of thermocouples in their service vans, so you never have to worry about parts availability.
The lifespan of a thermocouple depends on how long it has been in use — usually between 7 to 8 years, sometimes even longer.

It’s worth noting that the thermocouple is the most exposed and vulnerable part of your gas fireplace and often the one that requires replacement more frequently than other components

Gas control Valve

Gas Control Valve

In some cases, the issue is not caused by the thermocouple but by the gas control valve itself.
The valve may receive the signal from the thermocouple, but due to an internal fault or mechanical wear, it fails to recognize the voltage properly — causing the pilot light to go out.

So, when your pilot doesn’t stay lit, you’re usually facing one of two possible issues:
1. A faulty thermocouple, or
2. A malfunctioning gas control valve.

During diagnosis, the technician first replaces the thermocouple.
If the pilot still doesn’t stay on after replacement, the issue is likely with the gas valve.

When the gas valve fails, it’s typically one of the more expensive parts to replace.
However, our specialists can often offer cost-effective repair or replacement options — much cheaper than replacing the entire fireplace.
We carry all major types of gas valves with us for quick and professional service across the Lower Mainland

Thermopile (Power Generator)

Another component often found in gas fireplaces is the thermopile, sometimes called a power generator.
Its job is similar to the thermocouple, but it’s used in certain models — not all fireplaces have one.

In some brands, both parts exist together:
• The thermocouple keeps the pilot flame burning, while
• The thermopile provides power to the main burner, allowing it to open through the gas valve.

If the voltage output of the thermopile drops below 150 millivolts, it must be replaced.
Our licensed gas experts are fully equipped to diagnose and replace thermopiles of all models and brands.

Spark Ignitor

Another common issue in gas fireplaces is a faulty spark ignitor.
This usually happens in early fall when you try to relight your fireplace after the summer.
The ignitor may not spark properly due to dirt, debris, or corrosion around the pilot area — or it may simply be worn out.

Our technicians always have spark ignitors in stock and can replace them on-site quickly and affordably, ensuring your fireplace is ready for the heating season.

Wall Switch Problem

The most common type of service call we receive is related to this issue.
The sentence we hear from almost every customer, in one form or another, is:

“When I turn the switch on, even though my pilot light is on, my gas fireplace doesn’t turn on!”

This is a very common problem, and unfortunately, more than 90% of customers never think the issue could be related to the switch.
The reason is that most people don’t have electrical knowledge or experience in how voltage flows through a circuit.

The main function of the switch in a gas fireplace system is to connect or disconnect voltage to the gas control valve.
In most homes and apartments, the wall switches that builders install are not designed for millivolt systems (low-voltage circuits used by gas fireplaces).

The type of switches you see in the picture are designed for 120-volt electrical systems, and using them for a millivolt system is incorrect from the beginning.
Unfortunately, many builders and contractors don’t consider this — they use these inexpensive, high-voltage switches to save costs during construction.

As a result, after a few years, the millivolt current can no longer pass through the switch, simply because it wasn’t designed for it.
When this happens, the gas control valve doesn’t receive voltage, and the main burner won’t ignite.

The proper solution is to remove the incorrect switch and install a millivolt-compatible switch that matches the gas control system.
Our certified technicians are highly experienced in diagnosing and installing the correct type of switch, and they will solve this problem for you quickly and professionally
