Why Is My Gas Heater Not Igniting?

One of the most dependable forms of home heating is a gas heater. That does not, however, imply that they are indestructible and will always turn on and operate whenever you need them. They can suffer malfunctions, just like any other mechanical device. Failure to ignite and come on is one of the most prevalent problems with forced air gas heaters. It may be a really frustrating experience that leaves you feeling like you're on the verge of giving up.

If your gas heater is not igniting, keep reading this article, which has been compiled after consulting with certified and experienced Heating Experts technicians, to enable you to solve your gas heater problems easily by yourself.

Let’s begin with learning about the common gas heater ignition problems, and what you can do to fix them.

1. Check the Circuit Breaker

To save you from extra efforts, it's important to check these things first, which can bar your heater from igniting. For example, a circuit breaker. It can be tripped because of the power overload, and can stop the motor and burners from turning on.

2. Check the Safety Switch

Before looking for other possible ignition problems, and calling for a gas heater repair person, it is advised to check the safety switch first. If the switch is open, the burners of your heater won’t come on. However, this switch never opens without a problem with the heater. So, a safe move would be to call an HVAC technician to find out the problem.

3. Check the Gas Line

It’s obvious that your gas heater won’t ignite if the gas is turned off. So, make sure that the gas is turned on from the gas valve, which is usually located outside the house.

Or you can burn another gas appliance to see if the gas is on or not. If other appliances are burning without any problem, you should check the gas supply to the heater.

Insufficient gas supply caused by a leak can also result in ignition problems. Carefully examine the gas line to the heater to detect a leakage. You can also smell the gas in case of a leak. In this case, immediately evacuate the house, and call a professional gas heater maintenance service provider to deal with the emergency issue.

4. Rusty Burners

The next troubleshooting step is to check the burners of your heater. If they are dirty or rusty, your heater won’t ignite, as grime amassed across burners doesn’t allow the oxygen to reach the burners, which is essential for lighting them. Getting gas heater maintenance regularly prevents grime from amassing across burners.

5. Dirty Air Filters

A dirty or choked air filter can be a reason that your gas heater is not igniting. You can replace the air filter yourself to solve this problem.

6. Thermostat settings

You can also change the settings of the thermostat to solve gas heater ignition problems. Moving the thermostat to a higher setting can make the heater ignite.
