How to Replace a Plug on a Space Heater: A Comprehensive Guide

Replacing the plug on a space heater can be a straightforward task, but it requires attention to detail and the right tools. This comprehensive guide will walk you through the process step-by-step, ensuring you have all the necessary information to safely and effectively replace the plug on your space heater.

Gather the Necessary Tools and Supplies

Before you begin, make sure you have the following tools and supplies on hand:

  • Wire cutters
  • Wire strippers
  • Phillips head screwdriver
  • Replacement plug (ensure it matches the voltage and wattage of your space heater)
  • Slotted screwdriver (optional)
  • Utility knife (optional)

It’s important to choose a replacement plug that is rated for the correct voltage and wattage of your space heater. You can find this information on the label located on the back of the heater, which should indicate the voltage, frequency, and wattage.

Unplug and Disassemble the Old Plug

how to replace a plug on a space heater

  1. Ensure the space heater is unplugged from the power source to avoid the risk of electric shock.
  2. Locate the screws on the face of the old plug and use a Phillips head screwdriver to remove them.
  3. Gently pull the old plug upward to separate it from the outer housing.
  4. If there is a clamp at the base of the plug, you may need to remove it to allow the cord to pass through more easily.

Prepare the Cord for the Replacement Plug

  1. Use wire cutters to snip off the old, damaged plug.
  2. Slide the outer housing of the replacement plug down the cord’s length to gauge how much of the cord’s sheath must be stripped.
  3. Use a utility knife to carefully make a lengthwise slit in the cord’s outer casing, exposing the black, white, and green wires.
  4. Remove the outer sheath by making a circular cut around the cord and peeling away the black sheath.
  5. Depending on the orientation of the terminals inside the replacement plug, strip about 5/8″ of insulation from each of the individual wires.

Connect the Wires to the Replacement Plug

  1. Insert the ground wire (green) into the green screw terminal.
  2. Insert the neutral wire (white) into the silver screw terminal.
  3. Insert the hot wire (black) into the brass screw terminal.
  4. Tighten the terminals down by hand using a screwdriver.

Reassemble the Plug

  1. Slide the outer housing of the replacement plug back up to mate with the plug.
  2. Tighten down all accessory screws to finalize the connection with the cord.

Verify the Replacement Plug

  1. Ensure the replacement plug is rated for the correct voltage and wattage of your space heater.
  2. Check the label on the back of the heater for the voltage, frequency, and wattage specifications.
  3. In the example provided, the heater was labeled as 120V 60Hz 1500W AC ONLY, so a replacement plug rated for 125 volts and 15 amps with a ground should be sufficient.

By following these steps, you can safely and effectively replace the plug on your space heater. Remember to always prioritize safety and use caution when working with electrical components.
