Extreme voltage fluctuations will affect beater motor
amperage and, in turn, influence the product
appearance.
To change the off-cycle time on the solid state timer,
refer to the following resistance chart for thenecessary
resistor.

Watt Control Troubleshooting
Tools Required: A meter capable of measuring
millivolts.
Procedure: To verify proper operation of the Watt
control, connect the negative side of the meter to the
voltage regulator heat sink as indicated by the white
arrow that is printed near the center of the control.
Connect the positive side of the meter to the center
terminal of the viscosity potentiometer as indicated by
the black arrow.
If the beater motor is not active, the voltage will
measure between 0 and10 millivolts. The typical value
is 0. If the voltage is greater than 10 millivolts, there is
excess current leakage through the beater motor or
the control is defective.
If the beater motor is active, the voltage measurement
will be greater than 50 millivolts. If the voltage is less
than 10 millivolts, there is a fault connection between
the Watt control and therest ofthe control circuit, orthe
control is defective.
In addition to the appropriate voltage measurement,
thefollowingcriteriamustbemet:
S The compressor should cycle off at the
same voltage consistently.
S The voltage should increase as product gets
thicker.
S The compressor should cycle of f once the
voltage stops increasing.
If these critera are not met, the control is defective and
must be replaced.
