The most common cause is something called delayed ignition, which is when the pilot light is taking too long to ignite after the gas valve has been opened. This can cause a loud “clanking” noise as the gas builds up pressure before it is eventually ignited.
It is an indicator that the pilot light may need to be adjusted or cleaned.
Another reason your heater may be making noise when off is due to a worn-out motor fan. Even when the power is turned off, some of the internal fan components can still create friction and cause a loud, buzzing noise.
This is typically caused by a lack of regular maintenance, so it’s important to keep your heater cleaned and serviced regularly to prevent this from happening.
Lastly, if the noise is coming from the base of the heater rather than from the top, then it could be caused by rodents or other small animals living in the walls near the heater. In this case, you’ll need to have an exterminator come and remove the pests before the problem can be fixed.
Overall, if your heater is making noise when it is off, it’s important to determine the cause as soon as possible. Proper maintenance and regular check-ups should help keep your heater running smoothly and quietly.

Why does my furnace hum when its off?
When your furnace is off, it can cause a humming noise. This humming noise is typically caused by a very common issue called “Induction Hum”. This refers to the alternating current that is run through the motors and other systems in the furnace when it is off.
This current causes magnets in the induction motors to vibrate, creating a humming sound that can be heard coming from the furnace. In some cases, the sound can be quite loud and can last for several seconds before it stops.
The induction hum is typically louder when the power source is close to the furnace, such as if it is near an electrical outlet.
If the humming noise seems to be coming from the furnace when it is off, and it is not intermittent, then it is likely that there is a problem with the induction motor. In this case, you should have a professional technician inspect the furnace to determine what the issue is and have it repaired as soon as possible.
Can a dirty furnace filter cause a humming noise?
Yes, a dirty furnace filter can cause a humming noise in some cases. If the filter becomes very clogged with dirt and debris, it can cause the blower motor to work harder. This can cause a humming noise as the motor is forced to work harder and the vibrations may be heard throughout the house.
Additionally, the dirty filter can cause the furnace to run inefficiently which can also result in a humming noise. To reduce the humming noise and ensure proper operation of the furnace, it is important to check and change the filter regularly to keep the filter clear of dirt and debris.
When should I worry about my furnace noise?
You should be worried about your furnace noise if you hear any of the following: persistent rattling, buzzing, hammering, groaning, or screeching sounds. Additionally, it’s important to be aware of any sudden changes in the volume of furnace operation.
