Tips for Properly Wiring Your Furnace Blower Tips for Properly Wiring Your Furnace Blower

It is easy to wire a furnace blower without any professional help. It helps to save a lot of money usually paid as fees to the professional electricians. The tools and material required to complete the job include, a pencil, a screwdriver, a drill, some drywall anchors as well as a masking tape. Here are some tips to properly wire the furnace blower using these tools and materials.

Turn Off the Electricity

It is important to first turn electrical power off, which is being provided to the furnace blower through the circuit breaker box or the power panel. Identify the right circuit breaker and switch it off. After it is done, cover the switch with some masking tape so that it is not turned back on, while wiring the furnace blower.

Disconnect the Wiring

Remove the wiring meant for power supply from the furnace blower’s backside. Also see to it that the wires do not fall back into their place in the wall. Hence, a pencil should be used to wrap the wires around, so that they can not pass through the hole meant for the exit and the entry. In case there is no color code for the wires, they should be marked so that they can be attached to the right terminal.

Attaching the New Wires

While connecting the new wires, be careful to make the right connections. Make sure that the different wires that usually connect to the fan blower and the air conditioner are properly attached. Usually, connect the green wire to a terminal that is marked “G”. Sometimes, the terminal for the green wire is also green in color. The green color wire is typically used to offer power for operating the furnace fan blower. Then there is the terminal marked “Y”, which is used to attach the yellow colored wire. This particular wire is used to connect to the air conditioning facility.

Replacing the Mounting Plate

When the mounting plate has to be replaced, the wall studs have to be slid on after choosing the different holes for installing the mounting plate. There is no point in using the holes that were used earlier. This is because these holes may have become loose now. Installing the plate in these holes, may prove to be hazardous. In case no studs were used to install the furnace blower on the wall, use some drywall anchors for securing the furnace blower in a proper manner.

Some Important Things to Remember

Always check that the wiring going to the furnace blower is smaller in size than the wiring used to connect to the electrical outlets in the rest of the house. In case, the wires that connect to the furnace blower are as large as the outlet wires, you may have to replace the entire length of wires right from the main power source of the house to the furnace blower. Hire the services of a professional electrician to adjust the length of the house wiring.
