Fixing a Furnace That Wont Stay Lit

A broken furnace is a hassle to handle. There are multiple reasons this can happen, but one of the most common is an issue with the burners or related parts.

Newer models don’t rely on pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition stops working correctly, the burners can’t perform like they do normally.

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

  • The thermostat tells your furnace to activate.
  • Your furnace’s draft inducer fan starts to bring fresh air through 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 is burning.
  • The gas valve moves gas to the main burners, which are lit by the pilot light.
  • Your furnace then sends warm air throughout your home via ductwork.

If something goes wrong during this sequence, your furnace will deactivate for safety concerns. Or it might stop a few minutes into heating because it’s too warm.

A number of of these malfunctions can be repaired on their own, but others require professional help. When you want the finest furnace repair in Calgary, reach out to our heat Experts at 587-315-5271. We repair all brands and our services are supported by a 100% Satisfaction Guarantee for a year.*

Here are a number of the top reasons why your heating isn’t staying lit and what to do moving forward.

1. Malfunctioning Flame Sensor

Your furnace’s flame sensor is a safety component that informs your furnace when gas is ignited. If the sensor is dirty or damaged, it may work erratically or not at all. Even if the sensor is functioning normally, poor positioning leaves it unable to sense the flame to begin with. While you can start troubleshooting and cleaning this sensor right away, hiring a pro like A1 Chesney Service Experts will guarantee the problem is taken care of quickly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety procedures that shut it off if it gets dangerously hot. One of the most common causes is a clogged filter. We suggest checking your air filter monthly. If you can’t see light through it, change it.

3. Thermostat Isn’t Working Right

Your thermostat tells your furnace when it should heat your residence. When it’s not functioning normally, your furnace will require more energy to keep your home warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you have. We recommend checking your owner’s manual or manufacturer’s website for necessary troubleshooting instructions. If you still can’t get yours working, reach out to our Experts at 587-315-5271. We’ll uncover the problem swiftly and can replace your thermostat, if necessary.

Several of these issues, such as a dirty flame sensor or an overheated furnace, are due to a lack of routine furnace maintenance. It’s highly beneficial to have this service completed once a year, because it may help stop breakdowns, boost your furnace’s energy efficiency and might even make it last longer.
