Hi, This is Wayne with Sears Parts Direct.
Today, we’re going to talk about a few ways to repair a broken wire. Wires inside your
appliance can be pinched, burnt, frayed or broken. You can repair damaged wires using
a suitable wire connector. For safety, before performing any wire repairs, make sure to
disconnect power to your appliance. The first step in this repair is to strip the insulation
from the ends of the wire. Always use a wire stripper to strip off the insulation. Using
a knife or wire cutter could be unsafe and could also damage the wire strands inside
the insulation. Place one end of the wire into the correct size stripping hole. The
holes are marked by wire gauges – smaller numbers denote larger wire sizes. If you use
a hole that’s too small, you may pull off wire strands along with the insulation. Strip
1/4″ of insulation off the end of the wire. Once we’ve stripped the insolation, we’re
ready to fasten the wire ends together. Crimp wire connectors can be used when space inside
the appliance is limited or when you don’t have much wire slack to work with. This connector
is smaller than a wire nut and doesn’t shorten the existing wire. First, place the bare end
of the wire into the connector, leaving none exposed. Repeat the process for the other
wire end. Squeeze the connector firmly with a crimping tool so the crimp securely grips
the wire. Give the wire connector a couple of firm ‘tugs” to see that it’s connected
and tight. Crimped wire connections that could be exposed to water inside an appliance require
a heat shrink tube seal to protect the new connection from moisture. Always remember
to put the heat shrink tubes on the wire before you crimp the wire ends together. Cover both
ends of the connector with the heat shrink tube to create a good seal. Heat the tube
using a heat gun or hair dryer until the tube shrinks up and seals the crimp connector.
If that seems like too much work for you, you could always use a wire nut. Wire nuts
are good to use when you have plenty of wire slack and you’re not restricted by wire harness
space. Ceramic wire nuts with high temperature ratings should be used to connect wires in
ranges and other appliances that generate heat. Wiring connectors should match the temperature
rating of the wires that they’re connecting. To apply a wire nut, place it over the stripped
wire ends until it covers all of the bare wire. Slowly twist the wire nut clockwise
until it’s firmly secured. Give the wires a couple of tugs to make sure it’s on tight.
You don’t need to twist the wire ends together before you install the wire nut. When a wire
nut is used to connect wires exposed to moisture, seal the open end of the wire nut with silicone.
To repair a wire with a broken spade connector, cut off the existing connector and strip 1/4″
of insulation from the wire end. Put the new connector onto the end of the wire and use
a crimping tool to secure it to the wire. Give the wire connector a couple of firm ‘tugs”
to see that it’s connected and tight. Always check the continuity of the wire you repaired
before reassembling the appliance. Well I hope this video has helped you out today.
