THERMISTORCALIBRATION

To verify the calibration of the thermistor circuit, proceed as follows:

1.Disconnect the thermistor leads going to the circuit board.

2.Short the terminals at JP5 (thermistor calibration pins).

3.Press the “up arrow” and the “down arrow” keys to display the temperature. The temperature should read 158° F.

4.If not 158° F, adjust the Thermistor Calibration Potentiometer until the display reads 158° F.

5.Remove the jumper from the thermistor calibration pins and connect the thermistor leads to the circuit board.

REVERSINGDWELLTIME

This potentiometer is used to set the dwell time when the dryer has the reversing option. The dwell is the time from when the motor turns off to when it turns on again in the opposite direction. Turning the knob counter-clockwise increases the dwell time and turning it clockwise decreases the dwell time.

COMPUTERRESET

Push this button if the control “locks up”. Pushing this button will reset the control.

120/230V.SWITCH

This switch must be switched to the correct input voltage for the control to work. Applying 230V when switched to the 120 V position will blow fuses on the circuit board.
