Part #1169256 09/2008
The parts listed below are not part of the sealed refrigeration system and are available
separately.
START CAPACITOR - P/N: 1112805
The start capacitor is used to increase power during the start. This additional power
will help get the compressor running in case there is any back pressure.
STARTING RELAY – INCLUDED IN ASSEMBLY P/N 513506066
The starting relay is mounted in the terminal box on the outside of the compressor
under the housing. When the compressor fi rst starts up, the starting relay closes
and completes a starting circuit. When the compressor motor reaches operating
speed, the starting relay opens and breaks the starting circuit.
THERMAL OVERLOAD SWITCH – INCLUDED IN ASSEMBLY P/N 513506066
The thermal overload switch is mounted in the terminal box on the outside of the
compressor under the housing. If the compressor motor gets hot or draws too much
current, the thermal overload opens and breaks the starting and running circuit of
the motor. As the motor cools, the thermal overload closes, allowing the compressor
to restart.
TEMPERATURE SENSOR – P/N 1122924
The temperature sensor is mounted in the inlet airfl ow of the evaporator. This
monitors the air temperature and reports it to the electronic controller so that the
controller can operate the refrigeration system via the power box.
