How to Repair a Furnace That Wont Stay Lit

A broken furnace is exhausting to deal with. There are lots of reasons this may happen, but one of the most frequent is something wrong with the burners or associated systems.

Newer systems don’t rely on pilot lights to keep the furnace lit. Instead, they use electronic ignition. If this ignition is damaged, the burners can’t work like they do normally.

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

  • The thermostat informs 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 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 principal burners, which are lit by the pilot light.
  • Your furnace then pushes warm air across your home 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 too warm.

Some of these malfunctions can be resolved on their own, but others require professional assistance. When you want the finest furnace repair in Alliance, contact our furnace Experts at 330-235-1260. We service all brands and our work is supported by a 100% Satisfaction Guarantee for a year.*

Here are some of the most common reasons why your heating 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 faulty, it could work inconsistently or not at all. Even if the sensor is running like it should, misaligned positioning leaves it unable to identify the flame entirely. While you could start troubleshooting and cleaning this sensor by yourself, trusting a pro like Service Experts Heating & Air Conditioning will guarantee the problem is handled promptly and correctly.

2. Overheated Furnace

Your furnace has built-in safety functions that deactivates your furnace if it gets especially hot. One of the most frequent causes is a dirty filter. We encourage reviewing your air filter every month. If you can’t see light through it, replace it.

3. Thermostat is Malfunctioning

Your thermostat informs your furnace when it needs to heat your house. When it’s not running like it should, your furnace will require more energy to keep your home warm. This can be a battery or electrical issue, depending on what model of thermostat you own. We suggest reviewing your owner’s manual or manufacturer’s website for necessary troubleshooting info. If you still can’t get yours working, get in touch with our Experts at 330-235-1260. We’ll discover the issue promptly and can replace your thermostat, if necessary.

A number of these issues, including 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 once a year, because it can help stop breakdowns, increase your furnace’s energy efficiency and may even make it last longer.
