How to install capacitors on 14-inch motors

How to replace a motor capacitor?

Inspect the shape and dimensions of the old capacitor. This will help you find a replacement capacitor that fits properly in the available space. Now, you can source a new motor capacitor from online suppliers or local HVAC stores. Make sure to match the capacitor ratings and shape with the old capacitor.

How to wire a motor capacitor?

Here’s a step-by-step guide on how to wire a motor capacitor: Start by disconnecting the power source to the motor. This is essential to prevent any electrical shocks while working on the capacitor. Once the power is disconnected, locate the motor capacitor. It is usually a cylindrical-shaped object with two or three terminals.

Which side of a motor should a capacitor be on?

By which "side", the caps have to be on the correct terminals for Start (the start winding) and Run (the run winding) of your motor. But there's no right or wrong "side" otherwise. Surely your motor has terminals specified for its start and run capacitor connections.

Can a start/run electric motor capacitor be mounted in a different direction?

Start/run electric motor capacitors can be mounted in any direction or position. However there are some other capacitor mounting considerations that can affect capacitor life: basically you want to minimize the capacitor's exposure to vibration and heat. As AFCAP points out, ..."

How do you remove a motor capacitor?

Once the power is disconnected, locate the motor capacitor. It is usually a cylindrical-shaped object with two or three terminals. Use a screwdriver to remove the wires from the terminals of the old capacitor.

Do I need a new start capacitor for my fan motor?

This has stumped even long time mechanics. From your description, your system needs a new start capacitor for the fan motor. If you bought the proper capacitor then you may have wired it incorrectly. There will be a Start S and Run S terminal and a C common terminal.
