Blower Not Working On Electric Fireplace – How To Fix

The best way to enjoy a chilly winter night is to cozy up on the couch, watching TV, and eating a bowl of popcorn. With a fireplace blower, it won’t be necessary to stay beside the fire for heat.

A fully functional blower would ensure that you are snug right on the couch or anywhere else in the room.

Blower Not Working On Electric Fireplace

But what happens when the electric fireplace blower stops working? The heat would be concentrated around the fireplace, and the other parts of the room would be colder than before.

An electric fireplace is a beautiful addition to a home, but it can quickly become unpleasant without an operative blower.

Causes Of A Faulty Electric Fireplace Blower & How To Fix Them

Here are possible reasons for electric fireplace blower problems and their solutions.

Clogged Blower

A fireplace blower is a fan designed to circulate hot air around a room. It works by pulling cold air from the room and forcing it through the fireplace. The cold air then heats up in the fireplace and is pushed back into the room as hot air. The movement of air is essential for the effective circulation of heat.

If a blower cannot control the flow of air in a fireplace or has decreased airflow, it is clogged. Clogged blowers won’t put out as much hot air as expected and may fail to completely insulate a cold room.

The decrease is caused by a build-up of dust and lint in the vent of the blower. Until the particles are removed, the blower will not be able to perform effectively.


Fortunately, it is effortless to solve the problem of a clogged fireplace blower. You will need the following materials:

  • A painter’s tarp or an old sheet to protect the floor near the fireplace
  • Instruction manual
  • A small paintbrush
  • Pliers and screwdrivers

Carry out the following steps to clean the blower:

  1. Switch off your electric fireplace and ensure it is cool before you proceed.
  2. Consult the instruction manual for guidance on how to access the blower of your fireplace. For some electric fireplace models, simply unscrewing the front panel would grant you access to the blower fins. In others, you may have to bring out the blower assembly completely. Again, the manufacturer’s requirements would be the determinant.
  3. Once you gain access, clean each blower fin with a paintbrush.
  4. Clean the motor of the blower, and also wipe the cover.
  5. Avoid using liquid or wet materials to clean the blower as it may affect the electrical components of the assembly. Ensure you remove as much debris and dust as possible to improve the overall airflow.
  6. Reinstall the blower assembly and other components according to the manufacturer’s instructions.
  7. Test blower to confirm it works excellently.

Blower’s Circuit Breaker

An electric fireplace’s blower has a high voltage requirement. This can cause electrical problems for homes without upgraded circuit panels.

When the blower is turned on, and the energy requirement is more than the panel can provide, the circuit breakers of the electrical source would be tripped. Therefore, the blower and any other device connected to the panel would stop working.

Until the circuit panels of the home are correctly upgraded, it may be challenging to have a fully functional blower in your electric fireplace. This is a possible reason for an electric blower not turning on.

Switch For The Blower Is Bad

A blower of an electric furnace may not work if the switch or electrical outlet it is connected to is not operative. This can be confirmed by plugging another electrical device into the outlet used for the blower.

If the device powers on without any issues, the socket is fine. But if not, the socket would have to be replaced. Your blower should work fine after the replacement.

Damaged Electrical Wiring

After some usage, the blower motor may stop turning on automatically. First, access the control panel to check for power settings and ensure they are set.

Also, check the back of the panel for corrosion of electrical connections. If the wiring is rusted, chewed, frayed, or burned, the blower won’t work until the wires are replaced.

If the wires appear to be perfect, you need to test for the flow of electricity through them. This can be done with the following steps:

  1. Connect the blower/fireplace to an electrical outlet, then switch it on.
  2. Disconnect the two terminal wires from the motor on the fireplace blower assembly.
  3. Connect the multimeter probe tips to the location where the wire was disconnected. Zero display or infinite readings imply that the blower motor is burned out and needs to be completely replaced. However, if the multimeter produces a reading of 1 and above, the problem lies somewhere else.

Faulty Thermostat

Sometimes, when a fireplace’s blower fails to work, the problem may lie with the thermostat and not the blower itself. In some electric fireplace models, there are no separate switches for blowers as they have an in-built thermostat that automatically regulates the blower’s work.

In other cases, there are two outlets required for the fireplace and the blower. For the thermostat to perform its duties effectively, the switch must always be left on.

The thermostat would turn off the blower when the room reaches the desired temperature, and it will switch it on when the room starts to get colder.

In both models, when the thermostat malfunctions the blower won’t work because it cannot receive the proper directive. Carry out the following to confirm if the blower thermostat of your electric fireplace is fully operational:

  • Depending on the model, connect the blower or fireplace’s plug to an electrical outlet, then switch it on.
  • Disconnect the two wires connected to the thermostat in the blower assembly.
  • Connect the multimeter probe to the thermostat and check for electrical continuity.
  • An infinite or zero reading indicates that the thermostat is defective and requires replacement.


You will need the following materials:

  • Instruction manual
  • Pliers and screwdrivers
  • A painter’s tarp or an old sheet
  • Shop vacuum
  • A new thermostat

In order to fix the faulty thermostat:

  1. Determine the model of the thermostat attached to your blower and purchase a replica or a suitable alternative.
  2. Disconnect or switch off the fireplace and blower.
  3. Consult the instruction manual for guidance on how to remove the entire front panel of your electric fireplace.
  4. Detach the thermostat from the blower assembly, then clean the blower with a shop vacuum.
  5. Install the new thermostat and restore the panels of the fireplace.
  6. Connect the fireplace/ blower to an outlet and test for operation. The blower will start working once the fireplace is hot enough to trigger it. Also, watch out for the temperature set on the thermostat as it will determine when the blower goes off and on.

Final words

Electric fireplace blower issues are pretty common. A bi-annual tune-up should be done to the fireplace and blower assembly to keep the parts in peak performance.

In addition, it is recommended to employ the expert for professional servicing at least once a year.
