How to Fix Why My Electric Heater is Not Working

why my electric heater is not working

There are a few things you can do to fix an electric heater that isn’t working. These things include repairing or replacing the cord, getting the voltage right, or short-circuiting a wire.


There are several reasons that your electric heater may not work. One of the most common is a broken thermostat. Luckily, this type of repair is fairly straightforward. First, you’ll want to make sure that you unplug your unit. Next, you’ll need to find the thermostat’s location. Once you’ve figured that out, you’ll need to take off the nut that holds the thermostat in place.

After removing the thermostat, you’ll have access to the power switch. In some models, the switch is secured with screws or clips. However, it’s not unheard of for a switch to simply fall off. You can also remove the control housing, which can be done by removing the front grille.

You’ll also want to check out the fan. If you have a ceramic-based heater, you’ll want to clean the nozzles and plates. Also, you’ll need to clean the flue pipes.

Short-circuiting wire

It is a good idea to take steps to ensure that your electric heater is running properly. If you notice that your heater is not working, it may be due to a short circuit. This type of circuit can cause a lot of damage, so it is best to take action right away.

Short circuits can occur in both AC and DC electrical systems. These types of circuits are typically caused by loose attachments, damaged wiring, or faulty switches. When you encounter a short circuit, it is best to call a professional electrician to find the source of the problem and repair it.

To determine if you have a short circuit, you will first need to get a multimeter. Your multimeter should be able to show you if your appliance is receiving power or not.

Damaged power cord

If you are using a space heater and your electrical cord is faulty, you may not get the heat you expect. This can be a safety hazard, as it can lead to electrocution or even fire. But there are ways to repair the problem.

One of the first things you should do is check your cord to make sure there are no frayed wires. If there are, you will need to cut off the damaged section and replace it with a new one.

When deciding on a replacement, it’s a good idea to get a cord that isn’t too long. You can even cut it into smaller cords if you need to.

It’s also a good idea to get a continuity tester to test the wires. It’s a good idea to take the time to check for any loose wire connections, as these can lead to a short circuit.

Wrong voltage

If you have a wall-mounted electric heater that is not working, the problem may be the voltage. Whether you have a 120-volt or a 240-volt model, you will need to test and adjust the voltage. To do so, you will need a voltage detector, a shop vacuum, and a screwdriver.

The voltage detector is an electronic device that will perform a variety of tests to ensure that all circuit wires are connected properly. It will also check for short circuits, which can cause a fire or shock. A short circuit occurs when an electrical current flows outside of the established connections.

In some cases, a loose connection to the fuse box or a circuit breaker is the culprit. The circuit breaker can also trip when the heater is overheated. Depending on the type of heater, you may need to contact a qualified electrician to fix the issue.


The misuse of electric heaters can cause serious problems. This is why it is important to check your electrical equipment, and never leave them running unattended. Also, it is vital to prevent fires by following the guidelines outlined below.

Electric heaters are not designed to be permanent fixtures in your home. They are portable and only suitable for use in small rooms. It is recommended that you never place an electric heater near combustible surfaces. You also should not cover them to avoid flames. When an electric heater catches fire, it is best to call the fire department immediately. If you are using a coil space heater, it is especially important to stay away from combustibles.

If you plan to leave your electric heater running for an extended period, it is a good idea to purchase a thermal overload protector. Thermal overload protectors are devices that help keep wires from overheating. However, they can break down over time, if you do not monitor them.
