Repairing a Furnace That Wont Stay Lit

A broken furnace is tedious to handle. There are many reasons this might happen, but one of the most common is an issue with the burners or associated components.

Newer models don’t require pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition fails, the burners won’t function like they do normally.

When your gas furnace is functioning normally, here’s how it should work:

  • The thermostat directs your furnace to activate.
  • Your furnace’s draft inducer fan turns on to bring fresh air into your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor informs your furnace that the pilot is burning.
  • The gas valve directs gas to the primary burners, which are lit by the pilot light.
  • Your furnace then sends warm air throughout your residence via ductwork.

If something goes wrong during this sequence, your furnace will turn off for safety purposes. Or it might turn off a few minutes into heating because it’s overheating.

A number of of these issues can be resolved on their own, but others require professional help. When you want the fastest furnace repair in Winnipeg, contact our heating Experts at 204-800-0613. We service all brands and our work is supported by a 100% Satisfaction Guarantee for a year.*

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

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety feature that notifies your furnace when gas is ignited. If the sensor is dirty or faulty, it may work intermittently or not at all. Even if the sensor is operating normally, misaligned positioning leaves it unable to identify the flame at all. While you can attempt troubleshooting and cleaning this sensor on your own, calling a professional like Winnipeg Supply Service Experts will make sure the problem is fixed quickly and correctly.

2. Furnace is Too Warm

Your furnace utilizes built-in safety procedures that deactivates your furnace if it gets especially hot. One of the most frequent causes is a dirty filter. We recommend reviewing your air filter every month. If you can’t see light through it, swap it out.

3. Thermostat Malfunction

Your thermostat tells your furnace when it should heat your house. When it’s not functioning like it should, your furnace will struggle to keep your house warm. This can be a battery or electrical issue, depending on what type of thermostat you use. We suggest reviewing your owner’s manual or manufacturer’s website for necessary troubleshooting procedures. If you still can’t get yours working, reach out to our Experts at 204-800-0613. We’ll discover the cause swiftly and can replace your thermostat, if necessary.

Some of these issues, like a dirty flame sensor or an overheated furnace, are a result of a lack of proper furnace maintenance. It’s extremely helpful to have this service done yearly, because it can help reduce breakdowns, boost your furnace’s energy efficiency and may even make it survive longer.
