If you’d like to replace the thermostat on an electric fireplace for economic reasons or because you’d like something more up-to-date, there are many options available. However, service calls can be expensive and waiting around for them to fit you into a time slot somewhere between 8 a.m. and 5 p.m. can be frustrating. If you don’t want to call in a service guy, you can do it yourself by following these instructions:

Step 1 – Get the Right Thermostat 

Consult your owner’s manual to find out what voltage your system requires. You don’t want your new thermostat to be incompatible with the old system. Once you’ve determined your voltage, you can go shopping for your new thermostat. If you choose one in mid price range, that will give you a quality thermostat at a decent price.

Thermostats can save you a lot of money: it just depends which one you purchase. Programmable thermostats allow you to set the fireplace to turn on automatically and to choose what day or what time you want the fireplace to turn on. With any source of heat, if it is not running constantly but by specific economical programs, it can save you money. 

Step 2 – Turn Off the Power 

Locate your fireplace and thermostat on your breaker panel and shut off all power to the units. Make sure that you let everyone else in the house know that you are replacing the thermostat so that they don’t accidentally switch the power back on while you are still working. As a safety precaution, place a piece of electrical tape over the switch until you are through. 

Step 3 – Remove the Old Thermostat 

Remove the cover of your old unit. Detach the wires going to each terminal on the thermostat. Be sure not to damage any of the wires, and also label each of the wires that you remove with the letter or number at the terminal you disconnected them from. Now you can remove the old thermostat. 

Step 4 – Install the New Thermostat 

Install the new thermostat securely in the place of the old and reconnect the wires using the labels you created to match the terminals. The instructions that came with your new thermostat will answer any questions you might have. 

Step 5 – Do a Double-check 

Always make sure that you’ve connected all the wires securely to their terminals. Also, make sure you haven’t  made a mistake in connecting any wires. 

Step 6 – Replace the Face Plate 

Screw the face plate back into place. Make sure it is not crooked or missing any screws. 

Step 7 – Turn On the Power 

Switch the power to your fireplace and thermostat back on. Test out the new thermostat to see how it works. You’ll need to refer to the thermostat owner’s guide in order to program it to your specific needs.
