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

A broken furnace is tedious to deal with. There are many reasons this may happen, but one of the most frequent is a problem with the burners or associated systems.

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

When your gas furnace is performing normally, here’s how it should run:

    • The thermostat tells your furnace to turn on.
    • Your furnace’s draft inducer fan starts to pull fresh air through your furnace.
    • The gas valve opens to direct gas into the pilot burner.
    • An electronic spark lights the pilot light.
    • The flame sensor tells 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 into your house via ductwork.

If something malfunctions 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.

Some of these malfunctions can be handled on their own, but others require professional assistance. When you want the finest furnace repair in the U.S., get in touch with our heating Experts at . We repair all brands and our services are ensured by a 100% Satisfaction Guarantee for a year.*

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

1. Faulty Flame Sensor

Your furnace’s flame sensor is a safety feature that informs your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it could work erratically or not at all. Even if the sensor is functioning like it should, misaligned positioning leaves it unable to detect the flame at all. While you may try troubleshooting and cleaning this sensor right away, hiring an expert like Service Experts Heating, Air Conditioning & Plumbing will ensure the problem is fixed promptly and correctly.

2. Furnace is Too Warm

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 suggest reviewing your air filter every month. 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 operating like it should, your furnace will require more energy to keep your house warm. This can be a battery or electrical issue, depending on what model of thermostat you own. We encourage referring to your owner’s manual or manufacturer’s website for specific troubleshooting information. If you still can’t get yours working, get in touch with our Experts at . We’ll identify the problem swiftly and can replace your thermostat, if that is required.

Some of these issues, including a dirty flame sensor or an overheated furnace, are due to a lack of proper furnace maintenance. It’s vital to have this service completed every year, because it may help stop breakdowns, enhance your furnace’s energy efficiency and could even make it survive longer.
