REPLACE

CAUTION

Wafer switch terminals are easily bent and broken.

When installing a new switch containing wafers,

carefully position wiring harness to prevent strain

on switch terminals.

Place new switch in position.

On front panel, replace control knob retainer screw or hex nut.

On inside of front panel replace any hex nuts.

Solder wires to new switch.

Position transistor on compartment housing.

Replace screws, nylon bushing, lockwasher, nuts.

Solder wires to transistor terminals.
