3 Causes Why Your Furnace Isn’t Staying Lit and How to Solve It

A damaged furnace is a hassle to handle. There are multiple reasons this might happen, but one of the most common is a problem with the burners or associated systems.

Newer systems don’t count on pilot lights to keep the furnace lit. Instead, they work via electronic ignition. If this ignition is damaged, the burners will not work like they do normally.

When your gas furnace is running correctly, here’s how it should work:

• • The thermostat informs your furnace to run.

• • Your furnace’s draft inducer fan begins to spin in order to draw fresh air through your furnace.

• • The gas valve opens to move gas into the pilot burner.

• • An electronic spark lights the pilot light.

• • The flame sensor informs your furnace that the pilot is burning.

• • The gas valve sends gas to the primary burners, which are lit by the pilot light.

• • Your furnace then pushes warm air across your home via ductwork.

If something breaks down during this sequence, your furnace will deactivate for safety concerns. Or it might turn off a few minutes into heating because it’s overheating.

Some of these issues can be resolved on their own, but others are best handled by professional servicing. When you need the fastest furnace repair in the U.S., call our furnace Experts at . We repair all brands and our service is ensured by a 100% Satisfaction Guarantee for a year.*

Here are a few of the top reasons why your heating isn’t staying lit and what to do to fix it.

1. Malfunctioning Flame Sensor

Your furnace’s flame sensor is a safety component that tells your furnace when gas is ignited. If the sensor is dirty or damaged, it might work erratically or not at all. Even if the sensor is running as normal, poor positioning leaves it unable to detect the flame at all. While you may try troubleshooting and cleaning this sensor by yourself, contacting a professional like Service Experts Heating, Air Conditioning & Plumbing will make sure the problem is taken care of quickly and correctly.

2. Furnace is Too Hot

Your furnace contains built-in safety procedures that shut it off if it gets especially hot. One of the most typical causes is a filthy filter. We suggest evaluating your air filter every month. If you can’t see light through it, change it.

3. Thermostat Malfunction

Your thermostat informs your furnace when it is time to heat your residence. When it’s not running correctly, your furnace will require more energy to keep your house warm. This can be a battery or electrical problem, depending on what type of thermostat you have. We suggest checking your owner’s manual or manufacturer’s website for necessary troubleshooting instructions. If you still can’t get yours working, get in touch with our Experts at . We’ll find the problem swiftly and can replace your thermostat, if that is required.

A number of these issues, like a dirty flame sensor or an overheated furnace, are due to a lack of routine furnace maintenance. It’s extremely helpful to have this service done yearly, because it might help minimize breakdowns, boost your furnace’s energy efficiency and might even make it live longer.
