Can you replace a fan in a fireplace insert?

It is possible to replace a fan in a fireplace insert, but it requires some technical know-how. The fan is an important component in a fireplace insert, as it circulates heated air back into the room. Over time, the fan can wear out or break, necessitating a replacement. While a professional installation is recommended, a handy homeowner can replace the fan themselves if they have the right skills and take proper safety precautions. In this article, we’ll walk through the steps for replacing a fireplace insert fan, things to consider, and provide safety tips.

Why Would You Need to Replace the Fan?

There are a few common reasons why the fan in a fireplace insert may need replacing:

  • The fan is making loud noises or squeaking, indicating worn out bearings
  • The fan blades are visibly cracked or broken
  • The fan motor no longer powers on or spins
  • The fan is not effectively pushing heated air into the room
  • The fan is over 10 years old and nearing the end of its usable life

If you notice any of these issues with the fireplace insert fan, replacement is likely needed. Catching fan problems early is important to keep the fireplace operating safely and efficiently.

How to Replace a Fireplace Insert Fan

Here are the key steps involved in replacing a fan in a fireplace insert:

Turn Off Gas and Electricity

Before any work, make sure to turn off the gas supply to the fireplace at the shutoff valve. This eliminates the risk of any accidental ignition while working. Also turn off electricity to the fireplace at the breaker panel if it has an electrical connection for the fan, lights, or other components.

Remove the Surround Panel and Cover Plate

Most fireplace inserts have a decorative surround panel or mantel at the front. This will need to be detached and set aside to gain access. There will also likely be a metal cover plate protecting the internal fireplace components like the fan. Remove any screws securing this plate and take it off.

Detach and Remove the Fan

Locate the fan housing at the back of the fireplace chamber. It may be secured by several bolts or screws. Carefully detach the fan assembly from the fireplace body. The fan will also have electrical wiring connections that will need to be unplugged or uncovered. Make note of where the wires connect for re-installation. Gently pull the fan unit out from the fireplace cavity.

Purchase a Replacement Fan

Buy a new replacement fan designed specifically for your make and model of fireplace insert. The manufacturer’s name and model number can typically be found on a plate inside the fireplace. Take this information to your local hardware store, a fireplace specialist retailer, or search online. Make sure the airflow direction, capacity, and dimensions match.

Install the New Fan

Place the replacement fan into the fireplace cavity in the same position as the old one. Re-attach any wiring connections, making sure polarity is correct. Secure the fan housing back into the fireplace body using the hardware. Re-install any protective cover plates and re-attach the surround panel or mantel.

Restore Gas and Electricity

Once everything is re-assembled, restore power to the fireplace. Turn the electricity back on at the breaker panel. Open the gas valve to re-enable fuel supply to the insert.

Test Operation

Turn on the fireplace system per the manufacturer instructions. Let it ignite and burn for a few minutes. Verify that the fan turns on, stays on while burning, and blows heated air from the vents as intended. Confirm there are no gas leaks, smoke, or strange smells.

Key Safety Tips

When replacing a fireplace insert fan, keep these safety guidelines in mind:

  • Always turn off gas and electricity to the fireplace before disassembly
  • Wear protective gloves and safety goggles
  • Have a fire extinguisher on hand in case of accidental ignition
  • Avoid forcing or bending any gas lines
  • Double check all wiring connections are secure
  • Ensure no wiring is pinched or near hot or moving parts
  • Carefully follow the manufacturer’s instructions
  • Do not leave the fireplace disassembled for long – re-assemble as soon as the fan is replaced

Replacing a fan in a gas fireplace insert involves dealing with both electricity and combustible fuel. Take proper precautions for your safety. Consider having a professional service technician perform the replacement if you are unsure.

Signs You Need a Professional

While a do-it-yourself fan replacement is possible in many cases, there are some situations where it is best to call in a fireplace professional:

  • You cannot identify the exact replacement part needed
  • There are gas or wiring connections you are unsure how to detach/re-attach
  • The fan is not easily accessible within the fireplace
  • There are signs of other damage like cracks in the firebox or venting issues
  • You do not feel fully comfortable working on gas and electrical equipment

Professionals have specialized training, access to a wider range of replacement parts, and the expertise to safely troubleshoot other underlying issues. They can also properly dispose of the old fan.

Cost to Replace a Fireplace Insert Fan

The costs for replacing a fan in a fireplace insert can include:

  • Cost of the replacement fan unit – usually $80 to $250 depending on the type of fan
  • Labor costs if hiring a professional – often $200 to $400 including service call fee
  • Shipping charges if ordering the fan online
  • Disposal fees for the old fan if contracted

So in total, expect to pay anywhere from $100 for a DIY replacement up to $600+ if having a technician install a high-end fan. Get estimates beforehand if using a professional. The specific fan model and complexity of installation impact the overall cost.

Conclusion

Replacing the fan in a gas fireplace insert is an involved but doable DIY project for many homeowners. The key steps include turning off gas and electric, detaching the surround, removing the old fan, installing the replacement, reconnecting wiring, and testing operation. Follow all safety precautions when dealing with combustion appliances. Consider hiring a professional if certain complexities or issues arise during the fan replacement process. With some patience and care, a new fan can get your gas fireplace insert heating efficiently once again.
