Why Is My Furnace’s Electronic Air Cleaner Clicking?

Introduction;

Why Is My Furnace’s Electronic Air Cleaner Clicking One of the most common noises that come from your furnace or air conditioner is clicking. Whether you hear it when you turn on the heat in the fall or turn it off after you’ve left the house in the summer, it can be frustrating to try to determine why your furnace’s electronic air cleaner keeps clicking at you. Fortunately, these troubleshooting tips can help figure out why your furnace’s electronic air cleaner is clicking away and help you get it fixed so that you don’t hear those annoying sounds any longer.

Check the Filter

If you’ve noticed a clicking sound coming from your furnace, it could be due to several different factors. If the clicking is only audible when the furnace is running, it could be that the air cleaner needs to be replaced. However, if the clicking continues even when the unit is off and silent, you might have an issue with the blower motor. In this case, it would be wise to contact a licensed heating and cooling technician for more information. They will be able to diagnose and repair the problem as soon as possible.

Check the Coils

The clicking sound may be coming from the furnace’s electronic air cleaner, which is designed to capture dust and other particles that are released into the air. The furnace electronic air cleaner will click as it passes through the heating coils, which are a set of metal tubes that carry hot gas through your home for warmth. If these coils become dirty or clogged with debris, then they won’t heat up properly. As a result, you may notice that your furnace doesn’t seem to be blowing as much warm air as before or it might make a clicking noise while running.
Checking the coils is one way to troubleshoot this issue and keep your furnace in good working order. To access the furnace electronic air cleaner, turn off your furnace by pressing the power button on your thermostat or cutting power at the circuit breaker. Unplug any appliances near it and wait until all parts have cooled down completely before proceeding. After removing any debris on top of the coils, vacuum them out using a brush attachment to remove dirt and pet hair; clean around them using an old toothbrush dipped in water; wipe them down with a rag dipped in rubbing alcohol, or try vacuuming them with an electrostatic bagless vacuum cleaner. Continue checking until all dirt has been removed from the inside and outside of the furnace’s cooling unit. Replace any filters that need replacing and turn on your furnace once again!

Check the Blower Wheel

Blower wheels are a common component of an electronic air cleaner. They help move air through the filter to remove particles. If your blower wheel is clicking, it could be due to several factors.
The motor may have worn out and needs replacing. This can cause the blower wheel to become misaligned or tilt when it spins, which can result in the blades hitting each other and making a clicking sound. If you notice that your furnace is producing more heat than usual, this could also be an indication that your blower wheel needs replacing because excess heat may cause the bearings inside to wear out sooner than expected. It’s important to fix any problems as soon as they arise so they don’t lead to bigger issues down the road.

Call a Professional

Don’t worry, it doesn’t mean your furnace isn’t working. What you’re hearing is the electronic air cleaner clicking on and off. It turns on when the temperature in your home is below 65 degrees and off when the temperature rises above 70 degrees. The air cleaner runs for 30 minutes before shutting off. This is to prevent dirt and dust from accumulating in your furnace. If you continue to hear the clicking sound after a few days of normal operation or if it sounds louder than usual, call a furnace professional.

Conclusion

A furnace electronic air cleaner will click when the furnace is turned on to allow for a quick burn-off of any particulates or debris in the system. The clicking sound will last for about 10 seconds and then stop. There are many reasons why your furnace might be clicking, but most often it is caused by dust that has settled in the filter during a long period without use.
