located in the right front of the hood.
On brewers w/fresh light, the start switch is located

Location: CT/CWT/CWTF/TWINS
On most "CT" series brewers, the start switch is
located in the front of the hood.
On some "convertible" or "CS" brewers, the start
switch is located on either the right or left side of the
hood.
NOTE: Optional on the left and right side warmer
housings on 0/6 TWINS, connected in parallel to front
mounted start switches.
Test Procedure:
1. Disconnect the brewer from the power supply.
2. Disconnect the blue wire and the white/red wire
from the switch terminals.
3. Check for continuity across the two terminals on
the switch when it is held in the "pressed-in" posi-
tion. Continuity must not be present across these
terminals in the released position.
If continuity is present as described, reconnect the blue
wire and the white/red to the switch terminals.
If continuity is not present as described, replace the
switch.
Removal and Replacement:
1. Remove the blue wire and white/red from the start
switch.
2. Remove round retaining nut from the front of
the switch and remove switch and internal tooth
lockwasher from the inside of the hood.
3. Push new switch with internal tooth lockwasher
through the hole in the hood and secure with round
retaining nut.
4. Refer to Fig. 11 when reconnecting the wires.
