3 Causes Why Your Furnace Isnt Staying Lit and How to Repair It

A damaged furnace is a hassle to deal with. There are lots of reasons this may happen, but one of the most likely is something wrong with the burners or associated systems.

Newer models don’t count on pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition stops working correctly, the burners won’t perform like they should.

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

  • The thermostat tells your furnace to run.
  • Your furnace’s draft inducer fan turns on to draw fresh air toward your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor tells your furnace that the pilot has been lit.
  • The gas valve directs gas to the primary burners, which are lit by the pilot light.
  • Your furnace then distributes warm air throughout your residence via ductwork.

If something goes wrong during this process, your furnace will stop for safety reasons. Or it might deactivate a few minutes into heating because it’s too warm.

Several of these malfunctions can be repaired on their own, but others require professional help. When you want the finest furnace repair in Ravenna, contact our furnace Experts at 330-236-4793. We service all brands and our service is backed 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. 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 malfunctioning, it could work inconsistently or not at all. Even if the sensor is operating normally, poor positioning leaves it unable to identify the flame entirely. While you could try troubleshooting and cleaning this sensor on your own, contacting a professional like Service Experts Heating & Air Conditioning will guarantee the problem is fixed quickly and correctly.

2. Overheated Furnace

Your furnace contains built-in safety procedures that force a shutdown if it gets especially hot. One of the most common causes is a dirty filter. We encourage reviewing your air filter each month. If you can’t see light through it, replace it.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it needs to heat your residence. When it’s not running correctly, your furnace will have trouble keeping your home warm. This can be a battery or electrical issue, depending on what kind of thermostat you use. We recommend referring to your owner’s manual or manufacturer’s website for required troubleshooting instructions. If you still can’t get yours working, get in touch with our Experts at 330-236-4793. We’ll discover the issue right away and can replace your thermostat, if needed.

Some of these issues, like a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s extremely helpful to have this service performed yearly, because it may help reduce breakdowns, improve your furnace’s energy efficiency and could even make it survive longer.
