PROBLEM

Operator hears click sound when the temperature controller dial is turned but vessel remains cold. No evidence that elements are warming the vessel.

Poor temperature control on the cold side or hot side; excessive warm-up time; temperature recovery is slow or inadequate when vessel is loaded; uneven

heating; excessive temperature overshooting during warm-up; scorching; overheating; or high limit switch must be reset often.

CORRECTIVE ACTION

With the power switch “ON”:

1.Manually reset the high temperature limit switch (push red button on the panel above the drain valve). See Figure 6-1.

2.Check for tripped branch or main circuit breakers or blown fuses.

Check thermostat adjustment:

1.Check that the thermostat bulb/probe in the vessel has not been knocked loose from its operating position. It should be clamped to the second element with 1,5 mm (1/16 inch) spacing. See Figure 6-2.

2.Place the sensing bulb of a high quality immersion thermometer about 38 mm (1-1/2 inches) above the thermostat sensing bulb and set the temperature controller dial to 177°C (350°F).

3.Wait at least 30 minutes for the oil temperature to stabilize.

4.If temperature is not within +/- 5°C (10°F) of the dial setting, call service for a new operating thermostat/temperature controller.
