Motor
The motor has an automatic reset thermal overload protector.
If the motor overheats for any reason, the overload protector
will shut off the motor. The motor must be allowed to cool down
before restarting. The compressor will automatically restart
after the motor cools.
If the overload protector shuts the motor off frequently, check
for a possible voltage problem. Low voltage can also be
suspected when:
1.
The motor does not get up to full power or speed.
2.
Fuses blow out when starting the motor; lights dim
and remain dim when motor is started and is running.
