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

A damaged furnace is tedious to handle. There are lots of reasons this may happen, but one of the most frequent is a problem with the burners or related parts.

Newer systems don’t depend on pilot lights to keep the furnace ignited. Instead, they utilize electronic ignition. If this ignition fails, the burners won’t function like they do normally.

When your gas furnace is functioning properly, here’s how it should run:

• • 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 ignites the pilot light.

• • The flame sensor informs your furnace that the pilot has been lit.

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

• • Your furnace then distributes warm air across your residence via ductwork.

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

Several of these issues can be handled on their own, but others need professional servicing. When you need the top furnace repair in the U.S., reach out to our heat Experts at . We have experience with all brands and our service is backed by a 100% Satisfaction Guarantee for a year.*

Here are several of the typical reasons why your heater isn’t staying lit and what to do to fix it.

1. Malfunctioning 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 malfunctioning, it might work erratically or not at all. Even if the sensor is running like it should, poor positioning leaves it unable to detect the flame at all. While you could try troubleshooting and cleaning this sensor on your own, calling a pro like Service Experts Heating, Air Conditioning & Plumbing will make sure the problem is handled swiftly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety features that force a shutdown if it gets too hot. One of the most typical causes is a dirty filter. We encourage checking your air filter every month. If you can’t see light through it, swap it out.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it is time to heat your house. When it’s not functioning as it’s supposed to, your furnace will require more energy to keep your home warm. This can be a battery or electrical malfunction, depending on what model of thermostat you own. We recommend opening your owner’s manual or manufacturer’s website for specific troubleshooting procedures. If you still can’t get yours working, contact our Experts at . We’ll discover the issue swiftly and can replace your thermostat, if necessary.

A number of these issues, like a dirty flame sensor or an overheated furnace, are caused by a lack of consistent furnace maintenance. It’s highly beneficial to have this service performed every year, because it can help stop breakdowns, improve your furnace’s energy efficiency and could even make it live longer.
