E: Condenser Fan

This fan draws air from outside underneath
the truck and pushes it through the condenser coil
to cool the refrigerant flowing through the system.
The hot air is exhausted under the truck.

F: High Pressure Switch

This normally closed, brazed pressure switch will open
and prevent the operation of the compressor if high internal
pressure develops in the system. It is NOT serviceable.

G: Evaporator Sensor/Freeze Switch

This sensor stops and prevents the operation of the
compressor if ice was to form on the evaporator
coil. See appendix G page 14 for test instructions.

H: Sleeper Sensor

This sensor monitors the sleeper compartment
temperature. See appendix N page 16 for test
instructions.

I: Outside Air Sensor

This sensor monitors the air at the condenser coil.
See appendix O Page 16 for test instructions.
