How to Troubleshoot a Furnace That Wont Stay Lit

A faulty furnace is tedious to handle. There are many reasons this can happen, but one of the most likely is an issue with the burners or relevant components.

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 won’t perform like they do normally.

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

  • The thermostat directs your furnace to activate.
  • Your furnace’s draft inducer fan begins to spin in order 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 informs your furnace that the pilot has been lit.
  • The gas valve directs gas to the principal burners, which are lit by the pilot light.
  • Your furnace then distributes warm air across your residence via ductwork.

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

Some of these problems can be repaired on their own, but others require professional assistance. When you are looking for the finest furnace repair in Tulsa, call our furnace Experts at 918-212-8927.

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

1. Faulty 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 may work intermittently or not at all. Even if the sensor is operating like it should, misaligned positioning leaves it unable to recognize the flame entirely. While you could attempt troubleshooting and cleaning this sensor right away, trusting an expert like Jack Nelson Service Experts will make sure the problem is fixed promptly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety features that force a shutdown if it gets especially hot. One of the most typical causes is a clogged filter. We suggest checking your air filter each month. If you can’t see light through it, replace it.

3. Thermostat is Malfunctioning

Your thermostat directs your furnace when it should heat your home. When it’s not working properly, your furnace will have trouble keeping your house warm. This can be a battery or electrical malfunction, depending on what type of thermostat you have. We suggest opening your owner’s manual or manufacturer’s website for necessary troubleshooting details. If you still can’t get yours working, contact our Experts at 918-212-8927. We’ll find the cause promptly and can replace your thermostat, if needed.

Several of these issues, like a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s highly beneficial to have this service completed yearly, because it may help reduce breakdowns, boost your furnace’s energy efficiency and may even make it last longer.
