Restoring a Furnace That Wont Stay Lit

A malfunctioning furnace is tedious to put up with. There are many reasons this might happen, but one of the most frequent is something wrong with the burners or related systems.

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 will not perform like they are supposed to.

When your gas furnace is running normally, 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 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 transports gas to the primary burners, which are lit by the pilot light.
  • Your furnace then provides warm air across your residence via ductwork.

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

A number of of these problems can be handled on their own, but others are best handled by professional servicing. When you are looking for the finest furnace repair in La Porte, call our heating Experts at 281-407-9478.

Here are several of the top reasons why your heater isn’t staying lit and what to do moving forward.

1. Faulty Flame Sensor

Your furnace’s flame sensor is a safety feature that tells your furnace when gas is ignited. If the sensor is dirty or damaged, it could work inconsistently or not at all. Even if the sensor is running normally, poor positioning leaves it unable to recognize the flame at all. While you can attempt troubleshooting and cleaning this sensor by yourself, trusting a pro like Finch Air Conditioning & Heating will ensure the problem is handled swiftly and correctly.

2. Furnace is Too Hot

Your furnace has built-in safety procedures that shut it off if it gets too 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, swap it out.

3. Thermostat Isn’t Working Right

Your thermostat informs your furnace when it needs to heat your home. When it’s not operating as it’s supposed to, your furnace will require more energy to keep your house warm. This can be a battery or electrical problem, depending on what model of thermostat you own. We suggest checking your owner’s manual or manufacturer’s website for specific troubleshooting instructions. If you still can’t get yours working, contact our Experts at 281-407-9478. We’ll uncover the issue promptly and can replace your thermostat, if needed.

Some of these issues, like a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s important to have this service performed once a year, because it could help prevent breakdowns, boost your furnace’s energy efficiency and might even make it live longer.
