REMEDY

Remove the probe from the grom- met and submerge in a water bath of approximately 70°F(21°C). Con- nect an ohmmeter to pins 3 and 4 of the J3 connector. At 60°F(16°C) the reading should be 15.3k ± 2k OHMS, at 70°F(21°C) the reading should be 11.8k ± 2k OHMS, and at 80°F(27°C) the reading should be 9.3k ± 2k OHMS. If the probe is within these parameters, recon- nect the J3 plug to the control board.

Disconnect the brewer from the power source. Check for continu- ity across the limit thermostat ter- minals. Continuity should be present. If not replace the limit thermostat.(See page 26)

Disconnect the brewer from the power source. Check for continu- ity between the white terminal of the terminal block (or Red termi- nal on 208/240 volt models) and the black wire on the relay on the control board. There should be a low OHM reading. If no continuity is present, check for a wiring prob- lem, then replace the tank heater if no wiring problem is found. (See page 27)

Inspect probe and tank assembly for excessive lime deposits. Delime as required.
