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

A faulty furnace is frustrating to put up with. There are many reasons this may happen, but one of the most likely is something wrong with the burners or related systems.

Newer systems don’t use pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition stops working correctly, the burners won’t work like they do normally.

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

    • The thermostat informs your furnace to run.
    • Your furnace’s draft inducer fan starts 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 has been lit.
    • The gas valve transports gas to the primary burners, which are lit by the pilot light.
    • Your furnace then pushes warm air throughout your house via ductwork.

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

Several of these problems can be handled on their own, but others require professional servicing. When you want the finest furnace repair in the U.S., call our heating Experts at . We work with all brands and our services are supported by a 100% Satisfaction Guarantee for a year.*

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

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 could work intermittently or not at all. Even if the sensor is functioning like it should, misaligned positioning leaves it unable to sense the flame entirely. While you may try troubleshooting and cleaning this sensor right away, calling an expert like Service Experts Heating, Air Conditioning & Plumbing will make sure the problem is resolved swiftly and correctly.

2. Furnace is Too Hot

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

3. Thermostat Malfunction

Your thermostat commands your furnace when it should heat your home. When it’s not running normally, your furnace will have trouble keeping your house warm. This can be a battery or electrical problem, depending on what kind of thermostat you use. We recommend referring to your owner’s manual or manufacturer’s website for useful troubleshooting procedures. If you still can’t get yours working, get in touch with our Experts at . We’ll uncover the issue right away and can replace your thermostat, if necessary.

A number of these issues, like 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 performed once a year, because it could help prevent breakdowns, boost your furnace’s energy efficiency and might even make it live longer.
