What To Do When Your Natural Gas Furnace Is Not Working Properly

A natural gas heating system is quite easy to operate and maintain. But unfortunately, because of prolonged use or other circumstances, your natural gas furnace might begin to malfunction which is not something that you want.

Things to Check Before You Troubleshoot Your Furnace

Before you begin we strongly advise you to take these preliminary steps to eliminate possible unseen problems.

1. Check if your furnace is receiving power. You should look in detail at the state of the circuits at the entrance in the unit as well as around the unit.

2. Inspect if the unit has a RESET button, which is most of the time near the motor housing. Turn off your natural gas furnace and wait about 30 minutes for it to cool down, then press the button. If the furnace does not start, wait another 30 minutes and press it again. Repeat the procedure for the third time before you renounce on the idea.

3. Inspect your furnace for a second power switch and make sure that it is turned on.

4. Inspect your thermostat if it has been properly set. We also recommend that you increase the setting by 5 degrees as many modern thermostats have a 2-3 degree window besides the temperature set.

5. Make sure that your gas supply is turned on and the pilot light is functioning properly.

3 Main Reasons Why Your Natural Gas Furnace May Not Be Working Properly

If your natural gas furnace is not working properly then this is likely caused by the malfunction of one of the following three components:

  • the heat source;
  • the thermostat; or,
  • the distribution system.

Heat source problems: Your furnace might not receive the natural gas which is its fuel source and so it is not igniting.

Thermostat: If the natural gas furnace has random problems in turning on or it turns on and off repeatedly on a functioning cycle then the problem might be caused by a faulty thermostat.

Distribution System: If your natural gas furnace does turn on, but the warmth is not reaching the rooms of your house, then the problem is most probably related to the furnace’s distribution system.

Each of these requires extensive knowledge about how heaters work. You need to start with the basic procedures and admit when you are facing a furnace repair that you cannot handle yourself. In many cases, you can end up risking great damage or even injuring yourself by not calling a professional. 

Some Safety Advice

Before you start working on your natural gas furnace we recommend that you take note of the following:

  • Make sure that your furnace is completely powered off by removing the main fuse or if you are not sure power off the entire house. If the fuse of your house blows off when you power your furnace then this means that it’s an electrical problem and you need to consult a specialized electrician.
  • Make sure that there is no smell of gas in the house as this might indicate a gas leak. If you sense the smell of gas do not try to shut down the gas or power on any electrical device. Open the doors and windows, get outside of the house and call the gas company to report a leak. To not reenter the house.

No matter the problem is, if you still need specialized help, contact us and we’ll give you the best solution possible.
