The noise fi lter is mounted in a
recessed area in the PCB housing.
To access the noise fi lter:
1. Remove 3 screws from the
fi lter cover.
2. Disconnect the 2 lead wires.
3. Remove the 13-mm hex nut at
the end of the noise fi lter that
holds the ground wire in place.
To check the noise fi lter, look for
the epoxy molding to be broken
or burnt by heat or a power surge.
The noise fi lter resistance should
be approximately 500K Ω between
the black and red wires.
