6. Disassembly
6.1 Tools
Most of the tools that you might need are shown below. Some are optional.
ELECTRICAL PLIERS or STRIPPERS : For cutting and stripping small electrical wire.
VOM (VOLT-OHM METER): For testing electrical circuits. If you do not have one, please get one.
An inexpensive one will suffice, as long as it has both "AC Voltage" and "Resistance" (i.e.
Rx1, Rx10) settings on the dial. It will do for our purposes.
BUTT CONNECTORS, CRIMPERS, WIRE NUTS and ELECTRICAL TAPE: For splicing small wire.
When splicing wire on ovens, you must make sure you use high-temp connections, such as
porcelain wire nuts, high-temp terminals and fiberglass insulated wire.
ALLIGATOR JUMPERS (sometimes called a "CHEATER" or "CHEATER WIRE"): Available at
your local electronics store.
SCREW-DRIVERS: Both flat and Phillips head; two or three sizes of each. It's best to have at
least a stubby, 4-inch and 6-inch sizes.
NUT-DRIVERS, WRENCHS: You will need a 1/4 to 1/2 inch size.

have a tendency to tip forward, increasing the risk of personal injury.
3 Do not use door handle to lift or move the oven, which may result in personal injury.
NOTE:
Not all service procedures require that the oven be removed from the cabinet. See the
appropriate procedures to determine if removal from the cabinet is necessary.

will significantly reduce the lifting load. Removing the oven door will also provide the
technician a place to grip the oven when removing it from the wall.
Step 2: Remove the bake rack and bake tray from the oven.
Step 3: Remove the fixed screws that located inside the front frame on both sides of the
oven. (See the following figure).
Step 4: Pull the oven out of the cabinet toward you, using the gripping points and the handle
boxes on the sides. Hold the oven steady as you pull it out. Service procedures require that
the oven be pulled completely out of the cabinet.
