When To Replace a Fireplace Blower
There are a few signs that indicate it’s time to replace your fireplace blower:
- The blower is making loud or unusual noises when running
- The blower doesn’t turn on at all
- The blower seems to be running slower than normal
- You can see visible damage like cracked or broken blades
- The blower is over 10 years old
If you notice any of these issues, it likely means the blower motor is wearing out or there is an electrical issue. Replacing the unit is the best solution.
How to Replace a Fireplace Blower
Replacing a fireplace blower involves removing the old unit and installing a new blower. Here are the basic steps:
- Turn off the gas supply to the fireplace and let it cool completely if it has recently been used.
- Disconnect the wiring to the old blower unit. There is usually a junction box nearby that the blower wires connect to.
- Remove any screws or brackets securing the blower in place.
- Slide the old blower unit out and disconnect any remaining wiring or ducts.
- Install the new blower unit in the same position and remount the screws/brackets.
- Reconnect the wiring to the junction box.
- Turn the gas supply back on and test that the new blower powers on and runs properly.
Safety Tips
When replacing a fireplace blower, keep these safety guidelines in mind:
- Always turn off the gas to the fireplace before starting.
- Let the fireplace cool completely before working near it.
- Use caution when disconnecting electrical wires.
- Have a fire extinguisher on hand in case of emergency.
- Wear protective gloves and eye wear.
Replacing the blower may also require working in tight, enclosed spaces. Use caution in these conditions.
Finding a Replacement Fireplace Blower
The first step is determining the make and model of your fireplace so you can find the correct replacement blower. The manufacturer and model number are usually printed on a label inside the firebox.
Once you know the specific model, search online or check with a fireplace supplier. Provide them with the make and model and they can identify the right replacement part. Key details needed are:
- Blower dimensions (width, height, depth)
- Input power requirements (voltage, wattage)
- Air flow rate (CFM)
- Mounting bracket type
Many common models have replacement blowers readily available from retailers like Amazon or home improvement stores. For older or more obscure models, contacting the fireplace manufacturer directly may be needed.
Expect to pay $100-300 for a new blower assembly. Having a technician install it would add $200 or more to the total cost.
Conclusion
Replacing a faulty or failing fireplace blower is usually a straightforward DIY project. With some basic tools and safety precautions, a homeowner can swap in a new blower. The most important steps are:
- Determining the specific model of your fireplace.
- Finding a compatible replacement blower.
- Turning off gas and electricity to the unit before starting.
- Carefully removing the old blower and installing the new one.
- Reconnecting the wiring and ductwork.
- Testing operation before finishing.
With a little time and effort, you can replace a fireplace blower yourself and save the cost of professional installation. Just be sure to focus on safety and finding the correct replacement part.
Frequently Asked Questions
What tools do I need to replace a fireplace blower?
Basic tools like a screwdriver, wrench, pliers, and work gloves are usually sufficient. You may also need a power drill for removing screws. Have wire cutters/strippers to handle any electrical connections.
