Vent Blower
The vent blower is located at the top rear of the
microwave oven. See installation instructions for
the proper method of directing the vent fan prior to
installing the unit.
To remove the vent blower:
1. Remove the oven.
(See
Microwave
Oven Removal
.)
Check to make sure the fuse is not open. Check the
noise
fi
lter for approximate resistance value at the
following locations:
White (neutral input) to white (neutral output) – 0
Ω
.
Black (line input) to black (line output) – 0
Ω
.
White (neutral input) to black (line input) – 23
Ω
.
Line Fuse
Note:
When the line fuse is blown due to operation
of the monitor switch, the monitor switch must
be replaced. Also, the relays and/or the interlock
switches must be replaced when the continuity
check shows the contacts are shorted.
The unit is equipped with a 20-amp line fuse (Part #
WB27X10928). The fuse is located on a receptacle
near the top of the noise
fi
lter board and is common
to all functions and door switches.
To remove the fuse:
1. Disconnect power to the microwave oven.
2. Remove grille assembly. (See
Grille Assembly
.)
3. Remove control panel vent plate.
4. Remove the control panel assembly.
(See
Control Panel Assembly
.)
5. Remove the fuse. (See photo below.)
High Voltage Fuse
The unit is equipped with a 20-amp high-voltage
transformer fuse (Part # WB27X10928). The fuse is
located on a receptacle near the top of the noise
fi
lter board and is common to all high voltage
functions. (See
Line Fuse
for removal procedure.)

Noise Filter
The noise
fi
lter helps to suppress electromagnetic
interference (EMI) radiating from the operation of
the microwave oven, and it also protects the oven
from any line noise. The noise
fi
lter is located on the
right side of the oven, behind the control panel. The
noise
fi
lter is held in place by 3 compression pins.
Note
: When installing the noise
fi
lter, ensure all
fi
lter
wiring is connected to the correct terminals.
