6. Carefully bend the capillary tube so that the tube and bulb inside the tank are in a vertical position. NOTE: The capillary tube must be clear of any electrical termination and not kinked. 7. Fasten the new control thermostat to its bracket. 8. Refer to Fig. 7 when reconnecting the wires. 9. Adjust the control thermostat as required. BUNNOFF BLK to Tank Heater (100/120V) Thermal Fuse (230V) BLU/BLK to Limit Thermostat P2090.80 FIG. 7 CONTROL THERMOSTAT TERMINALS 37236 080504 Page 19 SERVICE (cont.) LIMIT THERMOSTAT FIG. 8 LIMIT THERMOSTAT P3047 Location: The limit thermostat is located inside the hood on the tank lid. Test Procedure: 1. Disconnect the brewer from the power source and remove the black wire from the limit thermostat. 2. With a voltmeter, check the voltage across the black wire removed from the limit thermostat and the white wire or red wire on the tank heater terminal. Connect the brewer to the power source. The indication must be: a) 120 volts ac for two wire 120 volt models. b) 230 volts ac for two wire 230 volt models. c) 100 volts ac for two wire 100 volt models. 3. Disconnect the brewer from the power source. If voltage is present as described, reconnect the black wire and proceed to #4. If voltage is not present as described, refer to the Wiring Diagrams and check the wiring harness. 4. Remove the blue/black wire from the limit thermostat. 5. With a voltmeter, check the voltage across the exposed terminal of the limit thermostat and the white wire from the power cord or the red wire from the power connector. Connect the brewer to the power source. The indication must be: a) 120 volts ac for two wire 120 volt models. b) 230 volts ac for two wire 230 volt models. c) 100 volts ac for two wire 100 volt models. 6. Disconnect the brewer from the power source. If voltage is present as described, reconnect the blue/ black wire to the limit thermostat. The limit thermostat is operating properly. If voltage is not present as described, replace the limit thermostat. Removal and Replacement 1. Remove both wires from the limit thermostat terminals. 2. Carefully slide the limit thermostat out from under the retaining clip. 3. Carefully slide the new limit thermostat into the retaining clip. 4. Refer to Fig. 9 when reconnecting the wires.

ON/OFF SWITCH FIG. 10 ON/OFF SWITCH P3034 Location: The ON/OFF switch is located in the front of the hood, above and to the left of the brew funnel. Test Procedure: 1. Disconnect the brewer from the power source. 2. Remove the black and white/violet wires from the switch terminals. 3. With a voltmeter, check the voltage across the black wire removed from the ON/OFF switch and the white wire on the 100 and 120 volt two wire, and red wire on the 230 volt two wire remaining on the switch terminal. 4. Connect the brewer to the power source. The indication must be: a) 120 volts ac for two wire 120 volt models. b) 230 volts ac for two wire 230 volt models. c) 100 volts ac for two wire 100 volt models. 5. Disconnect the brewer from the power source. If voltage is present as described, proceed to #6. If voltage is not present as described, refer to the Wiring Diagrams and check the wiring harness. 6. Check for continuity across the center and end terminals of the top row when the switch is in the “ON” position. If continuity is present as described, replace the wires, the switch is operating properly. If continuity is not present as described, replace the switch. Removal and Replacement: 1. Remove the wires from the switch terminals. 2. Compress the clips inside the hood and gently push the switch through the opening. 3. Push the new switch into the opening and spread the clips to hold the switch captive in the hood. 4. Refer to FIG. 11 when reconnecting the wires.

START SWITCH FIG. 12 START SWITCH P3034 Location: The start switch is located in the front of the hood, above and to the right of the brew funnel. Test Procedure: 1. Disconnect the brewer from the power source. 2. Remove the wires from all terminals. 3. Check for continuity across the two terminals on the right side of the switch when it is held in the lower position. Continuity must not be present across these terminals in the upper position. If continuity is present as described, reconnect the wires, the switch is operating properly. If continuity is not present as described, replace the switch. Removal and Replacement: 1. Remove the wires from the switch terminals. 2. Compress the clips inside the hood and gently push the switch through the opening. 3. Push the new switch into the opening and spread the clips to hold the switch captive in the hood. 4. Re...
