Repairing a Furnace That Wont Stay Lit

A broken furnace is tedious to handle. There are several reasons this can happen, but one of the most common is an issue with the burners or associated parts.

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

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

  • The thermostat tells your furnace to run.
  • Your furnace’s draft inducer fan begins to spin in order to draw 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 tells your furnace that the pilot is burning.
  • The gas valve directs gas to the principal burners, which are lit by the pilot light.
  • Your furnace then provides warm air throughout your residence via ductwork.

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

Some of these issues can be fixed on their own, but others are best handled by professional help.

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

1. Malfunctioning Flame Sensor

Your furnace’s flame sensor is a safety feature 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 functioning normally, incorrect positioning leaves it unable to recognize the flame entirely. While you may try troubleshooting and cleaning this sensor right away, contacting a professional like Broad Ripple Service Experts will ensure the problem is handled swiftly and correctly.

2. Overheated Furnace

Your furnace contains built-in safety features that deactivates your furnace if it gets dangerously hot. One of the most common causes is a dirty filter. We suggest evaluating your air filter monthly. If you can’t see light through it, replace it.

3. Thermostat is Malfunctioning

Your thermostat directs your furnace when it should heat your residence. When it’s not functioning as it’s supposed to, your furnace will struggle to keep your residence warm. This can be a battery or electrical malfunction, depending on what model of thermostat you own. We recommend reviewing your owner’s manual or manufacturer’s website for relevant troubleshooting procedures. If you still can’t get yours working, contact our Experts at 317-527-0271. We’ll pinpoint the issue right away and can replace your thermostat, if that is required.

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 crucial to have this service completed every year, because it may help reduce breakdowns, boost your furnace’s energy efficiency and might even make it last longer.
