Motor Thermal Overload Indicator

Figure 2

Located on the side of the control module is a small
indicator lamp with the above descriptive decal.

When this lamp is lit, it indicates that there is an open
thermal overload switch on the motor(s) which shuts
off the A.C. power to the computer board thereby
preventing damage to the motor(s) caused by
overheating and/or an overload condition.

This feature is provided to protect the motor and
extend the life of the motor. The thermal overload
switch will automatically reset itself after the
excessive heat condition has subsided; however, before
attempting to restart the machine, always check to find
out the reason for the overload (e.g., machine not fully
drained before spin, defective motor, continual out of
balance condition, low voltage, loss of one phase on
three phase motor, failed bearings, air circulation
blocked to motor fan). The thermal overload switch
should not open under normal operating conditions.
Failure to take corrective action when the indicator
lamp is lit will ultimately result in damage to the
motor(s).

If you have difficulty in locating the problem, do not
hesitate to call the factory.
