SERVICE (cont.) ON/OFF SWITCH (Warmers) READY SELECTOR ON / WARMER START START ON / WARMER SELECTOR READY Location: The ON/OFF switch(es) are located on the front of the hood next to the start switch(es). Test Procedure: 1. Disconnect the brewer from the power source. 2. Viewing the switch from the back remove the white or red wire from the upper right terminal and the black wire from the center terminal. 3. With a voltmeter, check the voltage across the white wire and the black wire or red and black wire. Connect the brewer to the power source. The indication must be: a.) 120 volts ac for two wire 120 volt models, three wire 120/208 volt models and three wire 120/240 volt models. b.) 200 to 240 volts ac for two wire 200 or 240 volt models. 4. Disconnect the brewer from the power source. If voltage is present as described, reconnect the white or the red wire, and proceed to #5. If voltage is not present as described, refer to the Wiring Diagrams and check the brewer wiring harness. 5. With the black wire removed, remove the white/ red wire on the left switch or the white/violet wire on the right switch from the lower left terminal. 6. Check for continuity across the center and lower left terminal with switch in the "ON" position. 1⁄2 gal 1 gal 1 1⁄2 gal FIG. 22 ON/OFF SWITCHES 1⁄2 gal 1 gal 1 1⁄2 gal P792 Page 24 Continuity must not be present when switch is in the "OFF" position. If continuity is present as described, reconnect the black wire to the center terminal and the white/red wire on the left switch or the white/violet on the right switch to the lower left terminal. If continuity is not present as described, replace the switch. Removal and Installation: 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 switch in the hood. 4. Refer to Fig. 23 when reconnecting the wires.

Screen #23721.0000) J2 J1 READY SELECTOR ON / WARMER START FIG. 24 OVERFLOW PROTEC- TION SWITCH START ON / WARMER SELECTOR READY Location: The overflow protection switch is located inside the hood on the tank inside the copper overflow cup. To test the overflow protection switch, access will also be needed to the level control board or electronic control assembly and terminal block. Test Procedure: 1. Disconnect the brewer from the power source. 2. Remove the wire nuts connecting the red wires from the overflow protection switch to the black wire from the terminal block and blue wire from the thermostat or the black and red wires from the electronic control assembly. 3. Check for continuity across the overflow protection switch red wires only until the plastic float is raised and check that continuity returns when the plastic float is again lowered. If continuity is present as described, reconnect the red wires to the blue wire from the thermostat and Liquid Level Control and the black wire from terminal block or black and red wires from electronic control assembly. If continuity is not present as described, replace the 1⁄2 gal 1 1⁄2 gal 1 gal 1⁄2 gal 1 1⁄2 gal 1 gal P2194 Page 25 overflow protection switch. Removal and Replacement: 1. Disconnect the red leads from the overflow protection switch from the blue wire from the thermostat and the black wire from the terminal block or black and red wires from electronic control assembly. 2. Remove the nut beneath the copper overflow cup. 3. Remove the entire switch assembly from the cup. 4. Place the new switch assembly into the cup, wires first. Make sure that the gasket is in place around the threaded switch stem. NOTE - The magnets must be at the top of float and there must be NO adjusting washers installed for the overflow protection switch to operate properly. 5. Install the nut beneath the copper overflow cup. Be sure not to overtighten. 6. Refer to Fig. 25 when reconnecting wires.
