3 Reasons Why Your Furnace Isn’t Staying Lit and How to Repair It

A damaged furnace is exhausting to deal with. There are many reasons this may happen, but one of the most common is a problem with the burners or relevant systems. 

Newer systems don’t rely on pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition is damaged, the burners can’t function like they should. 

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

  • The thermostat directs your furnace to activate. 
  • Your furnace’s draft inducer fan begins to spin in order to draw fresh air through 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 is burning. 
  • The gas valve moves gas to the primary burners, which are lit by the pilot light. 
  • Your furnace then transports warm air into your residence via ductwork. 

If something fails during this procedure, your furnace will shut down for safety purposes. Or it might stop a few minutes into heating because it’s getting too hot. 

Several of these problems can be resolved on their own, but others need professional help. When you want the top furnace repair in Clearwater, contact our heat Experts at 727-219-2471. We service all brands and our services are supported by a 100% Satisfaction Guarantee for a year.* 

Here are a few of the main reasons why your furnace 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 informs 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 functioning as normal, incorrect positioning leaves it unable to recognize the flame entirely. While you can start troubleshooting and cleaning this sensor by yourself, hiring a pro like Midway Services will guarantee the problem is resolved promptly and correctly. 

2. Furnace is Too Hot 

Your furnace uses built-in safety functions that shut it off if it gets dangerously hot. One of the most frequent causes is a clogged filter. We suggest evaluating your air filter each month. If you can’t see light through it, change it. 

3. Thermostat is Malfunctioning 

Your thermostat directs your furnace when it should heat your residence. When it’s not functioning like it should, your furnace will struggle to keep your residence 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 relevant troubleshooting information. If you still can’t get yours working, contact our Experts at 727-219-2471. We’ll identify the cause swiftly and can replace your thermostat, if necessary. 

Several of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of consistent furnace maintenance. It’s crucial to have this service completed yearly, because it might help minimize breakdowns, enhance your furnace’s energy efficiency and might even make it survive longer.
