Guide to Replacing Appliance Plugs and Power Cords

When an appliance plug or power cord is worn out or damaged, it is essential to replace them to ensure safety and optimal performance. This guide provides a step-by-step process for replacing appliance plugs and power cords. Follow these instructions to perform the task safely and effectively.

Replacing an Appliance Plug

To replace an appliance plug, you will need to purchase an appropriate plug based on the appliance's amp load. I recommend using models from reputable brands, such as Leviton or similar. Follow the specific directions provided on the box to ensure a proper installation.

Identify the size of the replacement plug based on the appliance's amp load. Purchase a suitable replacement plug. Brands such as Leviton are highly recommended. Disconnect the power source safely before proceeding with the replacement. Remove the old plug by cutting it off, ensuring the wires are free from the socket. Prepare the new plug by stripping the wire ends and placing the new cover over the wire. Follow the direction on the replacement plug, connecting the black wire to the gold screw, the white wire to the chrome screw, and the green wire to the green screw. Tighten the connections securely and install the cover. Secure the wire grips to hold the wire ends firmly in place.

Replacing the Power Cord on an Appliance

Replacing the power cord of an appliance can be slightly more complex depending on the model and the type of cord. Here are the steps you should follow:

Open the socket plug. If a screwdriver is needed to open the plug, use one carefully. Replace the old plug with a new one, ensuring the wires are properly connected. Secure the new plug using the screwdriver to tighten the connections.

For some appliances, you may need to use screwdrivers to access and remove the cord. Higher-end appliances may use Torx screws. The awkward part, if any, will be removing the glanded portion.

Replacing the Power Cord Properly

It is usually advisable to replace the power cord entirely. Cutting and joining the cord is not recommended. The new cord should ideally match the old one as closely as possible, including the colour coding. If the old cord's colour coding is outdated, consider modernizing it.

Before beginning, safely remove the old plug. This prevents accidents, such as Granny plugging you in while you are inside. Start by working on the appliance end, removing the old cord and noting the routes of the grommets, clamps, and terminations. Replicate these routes with the new cord, cutting the new cord to the appropriate length. If the appliance requires a non-rewirable plug, ensure the lead is granny-proof (safe for everyone) before proceeding. Test the continuity and isolation of the new cord with a multimeter or a portable appliance tester if available. Install all covers and test the appliance thoroughly to ensure everything is functioning correctly.

It is rarely worth the effort to replace the power cord on an appliance that is well past its prime. Appliances are almost never designed for such service, and replacing the cord alone may not significantly extend the appliance's lifespan.
