Why does my electric heater make a clicking noise?

Your heater’s heating elementOpens in a new tab. may need to be replaced if it sounds rattling. When an electrical current arcs over the heating element’s connections, a clicking sound is heard in the appliance. A clicking noise indicates an issue with the heater, so unplug it and get it fixed.

1. Your heater’s fan

If your heater includes a fan for circulating hot air into the roomOpens in a new tab., you should expect it to be noisy, especially if the heater is of low quality. For example, friction in the fan bearings can cause noise as they move. Also, it’s noisy when the fan’s blades and bearings are dirty or worn out or if there is insufficient oil.

To fix a noisy electric heater fan, follow these steps:

  • Start the heater with the electric knob.
  • Using a screwdriver, unscrew the fan.
  • Remove any apparent dust from the fan blades.
  • Remove the fan blades to locate the fan bearings.
  • Thoroughly clean and lubricate the fan’s bearings.
  • Replace the fan on the electric heater after it has been reassembled.
  • Fan bearings must be lubricated using a special lubricant. It takes more than WD-40 and machine oil to fix such delicate things.

2. Screws that have come loose.

Having loose screws in your heater’s housing causes the pieces to rub against each other and make a lot of noise. If you have a wall-mounted heater, check all the screws in the housing and the brackets for looseness or loosening. Increasing the volume is as simple as not securely fastening the components.

Due to loose screws, an electric heater may vibrate. The noise level will be amplified even further if your electric heater includes fans to circulate the air. As a result, ensure that your electric heater’s mounting hardware is secure. However, if you tighten them too much, there won’t be any wiggle space.

3. Incorrectly Installed Brackets for Attachment

Inadequately positioned installation brackets, related to the previous issue, might produce vibrations in the system. In addition, the electric heater may come free from the wall if the mounting brackets are too slack.

Find out whether the brackets were appropriately fitted by checking the user handbook. It is possible the brackets aren’t level, try to tighten the brackets even if everything looks in order.

4. The Bearings or Shafts of a Motor

Components in the furnace’s blower motor could make clicking noises as time goes on. A clicking sound from the blower motor seems to indicate that your heater needs to be serviced as fast as possible since deteriorated bearings could trigger the motor to blow out. In addition, the primary shaft that links the furnace’s blower fans to the motor might click when operating if it becomes rusted or blocked with debris.

5. Valves 

As air resistance increases and challenges with airflow occur, filters that have been kept on the burner for a lengthy timeOpens in a new tab. may generate clicking noises. A filthy air filter that has not been updated in a year or more may cause the heater to click and heat less slowly than average.

The solution to this problem is as simple as changing the filter and checking to see if the problem with clicking has been rectified, which is usually the case.

6. Vibrating Electric Coils

Your device’s electric coils are responsible for converting electrical energy into heat energy so that you may stay warm. Thermal energy is converted to kinetic energy when temperatures rise. As a result, you’ll hear a constant buzzing sound when you switch on your heater.

7. Heater Gas Valve

A lack of voltage may causeOpens in a new tab. the gas valve’s random and nonrhythmic clicks, which might indicate a malfunction. Fuel or avionics suite faults might create this chaotic behavior. Your heater may function occasionally or be entirely lit for just a few minutes because of the sputtering gas flow.

8. The Pilot Assembly for the Furnace

Though most burner pilot components don’t sound while trying to light a fuel oil or gas ignitor, there are a few exceptions. For example, when the pilot assemblies are too far removed from the oil or gas, they might twist and fail to ignite.

It is typical for bimetal pilot assemblies used in Carrier furnaces to stop operating and make a substantial clicking noise when dirty or worn.

Alternative heater models include cleaner-friendly pilot and insulator components, but these bimetal ones are more commonly changed.

How can I understand why my heating keeps on and off?

A short cycling interval is one of the most prevalent reasons for a furnace to cycle on and off repeatedly. The term “heating system difficulties” is used to describe them. You might have a damaged heating system and increased utility costs if you don’t catch short-circuiting early enough.

Can you tell me why my heater is producing this noise?

Many furnaces produce a clicking noise when they are initially switched on. The first time you start your car, you’ll hear this sound. As long as the clicking continues, you may have a severe issue with the Heating system.

How can I fix the clicking noise in my dishwasher?

There is a possibility that the lid is loose and making noises when the dishwasher is running. We’ll need to tighten the door’s latch to fix this issue. Also, make sure the timer is functioning correctly.

What can I do to prevent the heater from making a humming noise?

It’s important not to over-tighten the screws on the heater’s wall attachment. After the heater is installed correctly, loosen the screws by half a turn. This method will allow the metal to expand without causing unnecessary noise. Additionally, you must provide a minimum of 1/8 inch space between the molding and the sides of the baseboard heaters.

How do I stop my heater from clicking?

If you’re annoyed by radiator noises, the quickest and most straightforward solution is to bleed them. Bleeding radiators will aid in the elimination of any remaining air pockets, which should reduce the clicking sounds. However, it may be necessary to bleed numerous radiators around the house to purge the number of air bubbles thoroughly.


The clicking noise from an electric heater has previously been addressed in this article. According to the report, an overloaded heater may be to blame for this. You may want to unplug the heater and get it checked out by a professional if you can’t figure out what’s causing it.
