3 Reasons Why Your Furnace Isn’t Staying Lit and How to Repair It

A broken furnace is a hassle to put up with. There are multiple reasons this may happen, but one of the most likely is something wrong with the burners or associated systems.

Newer systems don’t use pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition fails, the burners can’t function like they are supposed to.

When your gas furnace is running normally, here’s how it should operate:

    • The thermostat informs your furnace to activate.
    • Your furnace’s draft inducer fan turns on to pull fresh air toward your furnace.
    • The gas valve opens to move gas into the pilot burner.
    • An electronic spark starts the pilot light.
    • The flame sensor informs your furnace that the pilot has been lit.
    • The gas valve sends gas to the central burners, which are lit by the pilot light.
    • Your furnace then moves warm air across your house via ductwork.

If something goes wrong during this sequence, your furnace will shut down for safety concerns. Or it might turn off a few minutes into heating because it’s getting too hot.

Some of these problems can be fixed on their own, but others require professional assistance. When you are looking for the finest furnace repair in Winnipeg, reach out to our furnace Experts at . We work with all brands and our work is ensured by a 100% Satisfaction Guarantee for a year.*

Here are a few of the typical reasons why your furnace isn’t staying lit and what to do about it.

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety system that informs your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it could work erratically or not at all. Even if the sensor is functioning like it should, incorrect positioning leaves it unable to detect the flame at all. While you may try troubleshooting and cleaning this sensor on your own, calling an expert like Winnipeg Supply Service Experts will guarantee the problem is handled quickly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety procedures that force a shutdown if it gets especially hot. One of the most common causes is a clogged filter. We recommend inspecting your air filter every month. If you can’t see light through it, swap it out.

3. Thermostat is Malfunctioning

Your thermostat informs your furnace when it should heat your residence. When it’s not operating properly, your furnace will have trouble keeping your home warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you have. We encourage reviewing your owner’s manual or manufacturer’s website for required troubleshooting instructions. If you still can’t get yours working, get in touch with our Experts at . We’ll uncover the problem quickly and can replace your thermostat, if that is required.

Several of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s important to have this service completed yearly, because it may help reduce breakdowns, increase your furnace’s energy efficiency and might even make it live longer.
