Attic Fan Replacement

Having an attic fan replacement once your old attic fan is no longer functioning is necessary especially during the hot summer months. An attic fan cools the inside of a house by pushing hot air from the inside of the house through a vent and allowing cool air to come in the house through the roof vents. The main function of attic fans is to cool your attic, which then may contribute to the drop of temperature inside your house.

Step 1-Turn Off the Main Power Supply

Wear your insulated gloves to prevent accidental electrocution. Locate the main power switch of your house and turn off the circuit breaker that supplies electricity to your attic fan. Remove the electrical wires that are attached to the fan by loosening the clamp that connects the wires to your attic exhaust fan. Using a screwdriver, remove the screws attaching the attic fan motor to your attic fan housing. Pull out your old attic fan.

Step 2-Install your New Attic Fan

Insert your new attic fan to the housing of your old fan. To be able to do this your attic fan replacement should be the same size as your old attic fan. After inserting your new attic fan to the fan housing remove the cover of the regulator. Attach the regulator into a rafter. Attach a cable clamp and insert all the cables through the clamp. Tighten the clamp. With a wire cutter or pliers, remove the sheathing strip from the wires.

Step 3-Attach the Wires

Attach the wires according to the wiring instructions that come with purchasing your attic fan replacement. Various types of attic fans are wired differently so make sure to consult your wiring instructions guide.

Step 4-Configure the Regulator

Insert the cover of the regular after you connect all the electrical wires. By now you will be able to configure your attic fan temperature control. Attic fans have different ideal settings for a balanced cooling effect and energy efficiency. However, the general ideal setting is around 95 degrees F.

Step 5-Test your Attic Fan

While still wearing your insulated gloves, turn on the circuit breaker that supplies electricity to your new attic fan. Test to see if your attic fan is working. If your attic fan is not working mostly likely it is due to incorrect wiring. Check your wiring instructions guide again and do the necessary wiring changes.

In working with anything that involves electricity it is always good to wear insulated gloves. To prevent your house member or friend from turning on the circuit breaker while you are working on your attic fan replacement you can put a Post-It note on the relevant circuit breaker that says ”Do not turn on; Replacing the attic fan.”
