Troubleshooting a Heater Making Clicking Noises


Are you dealing with an annoying clicking noise coming from your electric baseboard heater? It might be time to troubleshoot and find the root of the clicking sound. Whether it’s an untightened **** or an ignition sensor malfunctioning, learn about the most common causes of electric baseboard heater clicking and find the best solution for you.

Quick Summary

A common source of a clicking noise in an electric baseboard heater is untightened screws. Over time, the screws holding the heater position may become loose, causing the electric baseboard heater to vibrate and produce a clicking noise. Other possible causes of a clicking noise include a malfunctioning ignition sensor, low grease in electric baseboard heater, tickling of the heater radiator, poor heat dispersing fins, or a bad electric baseboard heater itself. To troubleshoot the problem, check the screws and tighten them if necessary, verify the ignition sensor is working, check the electric baseboard heater’s grease levels, and inspect the heat dispersing fins for any damage. If none of these solutions solve the issue, it may be worth considering replacing the electric baseboard heater.

Heater Making Clicking Noise? Troubleshoot with These Tips

Have you noticed your heater is making a clicking noise? A clicking sound coming from your electric baseboard heater can be alarming and bothersome, but wouldn’t you like to know why it’s happening? Discover the six leading causes of clicking sound in electric baseboard heaters and their possible solutions.

Untightened Screws

Once the electric baseboard heater keeps vibrating, it can become loose as the screws holding the heater position loosen with time. After the screws loosen, they will produce a clicking noise which increases with time. To solve this issue, you must tighten the screws.

Malfunctioning Ignition Sensor

An ignition sensor often controls the power that gets supplied to the heater. If the ignition control is faulty, it can cause a clicking sound to occur. To fix it, you should inspect the ignition sensor and see if it is functioning as expected.

Low Grease in Electric Baseboard Heater

Low grease in the heater is one of the main causes of the clicking sound. When the lubrication level falls, it can cause the clicking noise. To resolve this, the grease should be refilled with the help of a professional.

Tickling of the Heater Radiator

The radiating elements of the heater start making a ticking sound if they come in contact with an object. The buzzing sound stops once you move the object away from the heater. To prevent this issue, always keep the environment around the heater clean.

Poor Heat Dispersing Fins

When the fins bent or damaged the vibrations produced by the heater can make a clicking sound. The sound occurs because of the unbalanced flow of air across the fins. In order to troubleshoot this, the fins should be checked and corrected as needed.

A Bad Electric Baseboard Heater

Sometimes, the clicking noise is caused by a defect or a bad electric baseboard heater. To determine the exact cause and repair it, you need to get the heater checked by a professional. This will help ensure the electric baseboard heater is functioning properly.

Personal Experience

   Heater Making Clicking Noise? Troubleshoot with These Tips

I have years of experience in dealing with heaters making clicking noises in electric baseboard heaters. One of the most common issues I face is unscrewed components, which causes vibration and the subsequent clicking noise. To solve this problem, I usually identify the loose components and tighten them using appropriate spanner sizes. This helps prevent the vibration and the subsequent noise. I have also encountered malfunctioning ignition sensors in some of my cases, and a thorough inspection is mandatory to fix such problems. Low grease content in electric baseboard heaters can also cause a clicking noise. Adding grease to the affected areas usually solves this issue. Another issue I often come across is tickling of the heater radiator, which also produces clicking noises. Here, I usually use insulation pads to minimize the noise. Poor heat dispersing fins can also lead to high clicking noise, and this requires proper cleaning and fan replacement to resolve. Finally, a bad electric baseboard heater can also contribute to the clicking noise, and replacing the entire component addresses this problem.

Frequently Asked Questions

Is it normal for heater to make clicking noise?

Yes, it is normal for a furnace to make a clicking noise when it is first turned on. This sound is the ignition starting and indicates that the HVAC system is running as it should. If the clicking sound continues, however, it could indicate a serious problem that should be addressed.

Why does my heater igniter keep clicking?

If your heater igniter keeps clicking, it is likely because there is an ignition system malfunction. Your furnace’s spark igniter is trying to ignite the pilot light or burners, but is unable to do so. To get heat, you must fix the ignition system malfunction.

Is a clicking furnace dangerous?

Yes, a clicking furnace is dangerous. This type of noise is typically indicative of a problem with the gas valve or igniter, which can lead to potentially hazardous gas leaks. It is highly recommended that any noise coming from a gas furnace is immediately checked out by an HVAC professional for optimal safety.

What to do if furnace is clicking?

If your furnace is clicking, it could be due to buildup or worn out bearings on the fan shaft. To fix this problem, you should clean and lubricate the fan shaft to reduce wear. This preventative maintenance will help ensure furnace runs smoothly and efficiently.

Is a noisy furnace dangerous?

Yes, a noisy furnace can be dangerous. When there is a loud bang, rumbles, knocks, or booms, it can mean that something is wrong with the heat exchanger or ignition system and can even indicate that it could cause a serious problem if continued to be used. To avoid putting yourself or your family at risk, it is best to stop the heater and contact an HVAC professional to inspect the furnace and make repairs if necessary.

What does it mean when furnace is ticking?

When you hear ticking coming from your furnace, it usually means that the furnace’s spark igniter is attempting to ignite the pilot light or burners. If the ticking happens repeatedly, it likely indicates a system malfunction or failure. When this happens, it can be especially troublesome during the winter months when you rely on your furnace to provide heat.

What does it mean when your furnace makes a clicking noise?

A clicking noise coming from a furnace likely means that the inducer blower or fan shafts are clogged with build-up or that the bearings are worn out. Cleaning and lubricating the fan shafts can help solve the problem and prevent further wear. If neglected, the clicking noise can lead to premature wear on the main blower motor.

Why does my thermostat click but no heat?

The thermostat may click but no heat is produced if the furnace’s filter is clogged and restricting airflow. This can prevent it from creating heat. To resolve this issue, check and clean the filter regularly to ensure that your furnace has sufficient airflow.

What does a broken furnace sound like?

A broken furnace can sound like loud and frequent banging and popping noises. This can be caused by an issue with the ductwork, which can cause loud bangs and pops. If you experience these sounds from your furnace, it is best to call a professional for help to diagnose and fix the issue.

How often should your furnace click on?

Your furnace should click on an average of 3 to 8 times per hour. However, if your furnace clicks on more often than that, there may be other reasons behind it rather than short cycling. You should have a professional inspect your system to identify and solve the problem.
