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

A malfunctioning furnace is exhausting to put up with. There are lots of reasons this may happen, but one of the most likely is an issue with the burners or related components.

Newer models don’t rely on pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition malfunctions, the burners will not function like they should.

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

• • The thermostat informs your furnace to run.

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

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

• • An electronic spark starts the pilot light.

• • The flame sensor tells your furnace that the pilot has been ignited.

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

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

If something breaks down during this procedure, your furnace will shut down for safety purposes. Or it might shut down a few minutes into heating because it’s too warm.

Some of these issues can be resolved on their own, but others require professional servicing. When you need the finest furnace repair in the U.S., 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 several of the main reasons why your heating 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 damaged, it could work intermittently or not at all. Even if the sensor is functioning like it should, incorrect positioning leaves it unable to sense the flame to begin with. While you can start troubleshooting and cleaning this sensor right away, contacting a pro like Service Experts Heating, Air Conditioning & Plumbing will ensure the problem is handled promptly and correctly.

2. Furnace is Too Hot

Your furnace utilizes built-in safety functions that force a shutdown if it gets dangerously hot. One of the most frequent causes is a dirty filter. We recommend checking your air filter each month. If you can’t see light through it, replace it.

3. Thermostat Isn’t Working Right

Your thermostat commands your furnace when it needs to heat your home. When it’s not operating correctly, your furnace will have trouble keeping your home warm. This can be a battery or electrical issue, depending on what type of thermostat you have. We suggest referring to your owner’s manual or manufacturer’s website for useful troubleshooting information. If you still can’t get yours working, call our Experts at . We’ll discover the cause right away and can replace your thermostat, if necessary.

Several of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of proper furnace maintenance. It’s vital to have this service completed annually, because it can help reduce breakdowns, enhance your furnace’s energy efficiency and can even make it survive longer.
