If the blower switch on your electric fireplace doesn't turn on, it could be due to a few different issues. Here are a few troubleshooting steps you can try:

1. Check the power source: Ensure that the electric fireplace is plugged in and receiving power. If the unit is plugged in and still not working, try plugging it into a different outlet to see if that resolves the issue.
2. Check the blower motor: If the power source is good, the issue could be with the blower motor itself. Turn off the power to the fireplace and remove the access panel to the blower motor. Check for any obstructions that may be blocking the motor from turning. Also, check to see if the motor is hot to the touch, as this may indicate that it has overheated and needs to be replaced.
3. Check the switch: If the blower motor is not obstructed and doesn't seem to be overheating, the issue could be with the blower switch. Turn off the power to the fireplace and remove the access panel to the switch. Check the switch for any damage or signs of wear. If the switch appears to be damaged, it will need to be replaced.

If you're uncomfortable with troubleshooting electrical components on your own, it's best to contact a professional technician for assistance.

'make model (what it is)' in all questions please.

There are no fuses to look for. Just overload circuitry. However, before you do anything else, turn the Master Control ON/OFF Switch to OFF. Unplug the fireplace and wait 12 to 15 minutes, before plugging it back in. This will give the circuity time to reset itself. Once it;s plugged back in, turn on each function one at a time to see if it works. If it does, problem solved. However, if having to reset the unit becomes more frequent, contact the Technical Service Dept, of the manufacturer.

Hope this helps you to solve the problem.

If you no longer have your Owners Manual go to the Dimplex home page and click on the Help tab. You should be able to download the Owners Manual for your model fireplace there in a pdf format. Also look for a Trouble Shooting tab.
