Aren’t you frustrated enough while trying to figure out why your electric heater isn’t working properly? For many years, people have used electric heaters as a source of heat in their houses to keep off cold, especially in winter months. Compared to other heat sources, they are less expensive to buy and help you stay warm, which adds more to their appeal.

In this post, we’ll discuss the causes of electric heater issues and solutions. We’ll also explain how electric heaters work and when to call a professional if your heater system starts to break down. So, let’s get going!

How Do Electric Heaters Work

Electric heaters are frequently stand-alone HVAC devices that use electricity to produce heat. Oil-filled and dry cores are the two primary types of core used in electric radiators and heaters. Dry core heaters and radiators are frequently composed of ceramic, which makes them lightweight and leak-proof.

When the heater is in use, electricity runs through the heating element, which uses the electrical resistance to generate heat. Your home will have a comfortable heat temperature that is transmitted from the element as it heats up to the core, which is then conducted by the heater’s casing and ultimately transferred to the surrounding air.

The way the components of electric radiators are made allows them to heat rooms by a combination of radiation and convection. Their steel or aluminum bodies efficiently transfer heat from the outside into the space, and their housings’ fins maximize air contact to quickly warm areas.

Potential Causes of Electric Heater Issues

The first and most crucial item we should discuss is the particular situation of tripped circuits and overloaded residential electrical systems. Circuit breakers that trip frequently may indicate that your home’s electrical system isn’t built to support your appliances, including your heater. 

Thermostat Problems

Malfunctioning thermostats can lead to temperature inaccuracies or heating element issues. It may be due to a faulty thermostat sensor or a problem with the thermostat settings.

Heating Element Issues

Over time, heating elements can wear out or become damaged. This can result from factors like corrosion, mineral deposits, or electrical issues. If the heating element is faulty, it may need to be replaced.

Electrical Problems

Electrical issues can stem from problems in the wiring, the power source, or the internal components of the heater. It’s essential to check for loose connections, damaged wires, or issues with the power supply.

Airflow Obstructions

Restricted airflow can result from clogged air filters, blocked vents, or a buildup of dust and debris inside the heater. Proper airflow is crucial for efficient heat transfer, and obstructions can lead to overheating and potential damage.

Common Electric Heater Issues and Their Fixes

Your electric heater might not be turning on for different reasons: a broken fuse, a tripped circuit breaker, an electrical cable issue, or an issue with the power supply.  To make the most of your heater’s performance, you need to look into possible fixes.

Clogged or Unclean Air Filter

An unclean or clogged air filter may be the source of the heater’s overheating and shutting. Unplug and turn off the heater to remedy this. After removing the air filter, vacuum it or use a soft brush to clean it. Replace the damaged filter with a new one.

Lack of Maintenance

A malfunctioning heater may result from a lack of maintenance. To correct this, maintain the heater according to the manufacturer’s recommended schedule and give it regular cleanings.

Problems with the Thermostat

If the thermostat isn’t functioning properly, the heater cannot turn on or off when it should. Check the thermostat’s settings and, if needed, replace it to rectify this.

Fuse Box Malfunction

The heater may cease operating if the fuse box isn’t functioning properly. Examine the fuse box and replace any blown fuses to resolve this.

Blocked Ducts

A blocked duct may lead to overheating and eventual heater shutdown. Unplug and turn off the heater to remedy this. After removing the ducts, vacuum or use a soft brush to clean them.

Dead Blower Capacitor

The heater might not function correctly if the blower capacitor is dead. Replace the blower capacitor to resolve this.

Broken Heat Exchanger

The heater may stop working if the heat exchanger is damaged. Replace the heat exchanger to resolve this.

Blocked Chimney Exhaust Flue

The heater may stop functioning if the chimney exhaust flue becomes blocked. Examine the chimney exhaust flue and clear any obstructions to resolve this.

When to Call Professionals for Electric Heater Issues

A broken heater in the dead of winter is the last thing you want to happen. Bring in the experts if you are unable to solve the issue or require aid with troubleshooting. It’s advisable to contact a professional to identify and fix the electric heater issue that is giving you any of these problems. Trying to solve the problem on your own could result in more harm or even more damage.

  • Unusual noises — If your electric heater is producing odd noises, such as banging, rattling, or shrieking, there may be a major issue. Before more harm is done, an expert can identify the problem and resolve it.
  • Low or no heat — A broken thermostat, a damaged heating element, or a clogged air filter could be the cause of your electric heater’s low or nonexistent heat output. An expert can locate the issue’s primary cause and effectively fix it.
  • Bad odors — If your electric heater is emitting strange aromas, like a burning or musty smell, it may indicate a major issue. Before it does more damage, an expert may locate the source of the stench and address it.
  • High energy bills — A broken part or an obstructed air filter may be the cause of your electric heater’s higher-than-normal energy consumption. By locating the issue’s primary source and implementing effective solutions, an expert can lower your energy costs.
