4. Check the voltage across the blue/black wire on the thermostat and the white or red wire at the terminal block with a voltmeter when the thermostat is turned “ON” (fully clockwise). Connect the dispenser to the power source. The indication must be as described in step 2. Voltage must not be indicated when the thermostat is turned “OFF” (fully counterclockwise). 5. Disconnect the dispenser from the power source. If voltage is present as described, the thermostat is operating properly. If voltage is not present as described, replace the thermostat. Removal and Replacement: 1. Remove both wires from the thermostat terminals. 2. Remove the top lid from the dispenser to gain access to the thermostat bulb. 3. Remove the thermostat bulb by firmly pulling up on the capillary tube at the tank. This will disengage the grommet from the tank. 4. Remove the two #6-32 screws holding the thermostat to the mounting bracket. 5. Fasten the new thermostat to the mounting bracket. NOTE: Make sure that the capillary tube is away from any electrical termination and is not kinked. 6. Slide the grommet to the red mark on the capillary tube. 7. Insert the bulb through the hole in the tank and press the grommet firmly and evenly so that the groove in the grommet fits into the tank. 8. Refer to FIG. 10 when reconnecting the wires. 9. Readjust the thermostat dial as required. P1781 FIG. 9 THERMOSTAT BLU/BLK to Limit Thermostat BLK to Terminal Block P1782 FIG. 10 THERMOSTAT WIRING 10267 071900 SERVICE (cont.) Liquid Level Board P1783 FIG. 11 LIQUID LEVEL BOARD Location: The liquid level board is located inside the lower panel. Test Procedure: 1. Disconnect the dispenser from the power source. 2. Remove the blue wire from terminal 1 and the pink wire from terminal 4 of the circuit board. 3. Check the voltage across terminals 2 and 3 with a voltmeter. Connect the dispenser to the power source. Turn the thermostat knob to the “ON” position (fully clockwise). The indication must be: a.) 100 to 120 volts ac for 100 to 120 volt models, b.) 200 to 240 volts ac for 200 to 240 volt models, c.) 230 volts ac for 230 volt models. 4. Disconnect the dispenser from the power source. If voltage is present as described, proceed to #5. If voltage is not present as described, refer to the wiring diagrams and check the wiring harness. 5. Reconnect the blue wire to terminal 1. 6. Carefully connect a piece of insulated jumper wire to terminal 4. Keep the other end of this wire away from any metal surface of the dispenser. 7. Check the voltage across terminals 1 & 3 with a voltmeter. Connect the dispenser to the power source. Turn the thermostat knob to the “ON” position (fully clockwise). The indication must be: a.) 100 to 120 volts ac for 100 to 120 volt models, b.) 200 to 240 volts ac for 200 to 240 volt models, c.) 230 volts ac for 230 volt models, after a delay of approximately 5 seconds. 8. Touch the free end of jumper wire to the dispenser housing. The indication must be 0. 9. Move the jumper wire away from the dispenser housing. The indication must again be: a.) 100 to 120 volts ac for 100 to 120 volt models, b.) 200 to 240 volts ac for 200 to 240 volt models, c.) 230 volts ac for 230 volt models, after a delay of approximately 5 seconds. 10. Disconnect the dispenser from the power source and remove the jumper wire from terminal 4. If voltage is present as described, the level control board is operating properly, proceed to #11. If voltage is not present as described, replace the level control board. 11. Reconnect the pink wire to terminal 4. 12. Gently pull the probe out of the tank and inspect for corrosion. Replace it if necessary. 13. Place the probe so that neither end is in contact with any metal surface of the dispenser. 14. Check the voltage across terminals 1 & 3 with a voltmeter. Connect the dispenser to the power source. Turn the thermostat knob to the “ON” position (fully clockwise). The indication must be: a.) 100 to 120 volts ac for 100 to 120 volt models, b.) 200 to 240 volts ac for 200 to 240 volt models, c.) 230 volts ac for 230 volt models, after a delay of approximately 5 seconds. 10267 071900 15. Move the probe’s flat end to the dispenser housing. The indication must be 0. 16. Move the probe’s flat end away from the dispenser housing. The indication should again be: a.) 100 to 120 volts ac for 100 to 120 volt models, b.) 200 to 240 volts ac for 200 to 240 volt models, c.) 230 volts ac for 230 volt models. 17. Disconnect the dispenser from the power source. If voltage is present as described, reinstall the probe, the level control board and level probe are operating properly. If voltage is not present as described, check the pink probe wire. Removal and Replacement: 1. Remove all wires from the level control board. 2. Remove two #8-32 screws holding level control board and mounting bracket to the component bracket. 3. Install the new level control board and mounting bracket to the component bracket. 4. Refer to FIG. 12 when reco...
