Fixing a Furnace That Wont Stay Lit

A broken furnace is a hassle to put up with. There are multiple reasons this can happen, but one of the most frequent is something wrong with the burners or related systems.

Newer furnaces don’t use pilot lights to keep the furnace lit. Instead, they work via electronic ignition. If this ignition stops working correctly, the burners will not perform like they are supposed to.

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

  • The thermostat directs your furnace to turn on.
  • Your furnace’s draft inducer fan turns on to pull fresh air into 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 primary burners, which are lit by the pilot light.
  • Your furnace then moves warm air into your residence via ductwork.

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

Several of these problems can be resolved on their own, but others need professional servicing. When you need the top furnace repair in Atlanta, contact our heating Experts at 678-235-9699. We have experience with all brands and our work is supported by a 100% Satisfaction Guarantee for a year.*

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

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety component that notifies your furnace when gas is ignited. If the sensor is dirty or faulty, it might work erratically or not at all. Even if the sensor is working as normal, incorrect positioning leaves it unable to recognize the flame to begin with. While you could attempt troubleshooting and cleaning this sensor on your own, contacting an expert like Peachtree Service Experts will make sure the problem is taken care of swiftly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety features that deactivates your furnace if it gets too hot. One of the most common causes is a clogged filter. We recommend inspecting your air filter each month. If you can’t see light through it, swap it out.

3. Thermostat Malfunction

Your thermostat directs your furnace when it should heat your house. When it’s not functioning normally, your furnace will struggle to keep your residence warm. This can be a battery or electrical malfunction, depending on what type of thermostat you use. We encourage referring to your owner’s manual or manufacturer’s website for relevant troubleshooting information. If you still can’t get yours working, contact our Experts at 678-235-9699. We’ll find the cause quickly and can replace your thermostat, if that is required.

A number 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 done yearly, because it might help minimize breakdowns, improve your furnace’s energy efficiency and could even make it live longer.
