Low-pressure gauge reading is above normal. For normal operating pressures, refer to Table 1.
High-pressure gauge reading is below normal. For normal operating pressures, refer to Table 1. Note: Ambient temperature is above 21°C (70°F).
Air flow to the operator's compartment is warm. Probable Cause
The thermostatic switch is stuck open. This does not allow the magnetic clutch to cycle the compressor.
Check the wire connectors on the thermostatic switch and on the magnetic clutch.
The connection of wire leads on switch is improper. The connection of wire leads on the magnetic clutch is improper.
Check for insulation that is broken. The insulation failure can expose the wires from the switch to the magnetic clutch.

Low-pressure gauge reading is below normal. For normal operating pressures, refer to Table 1.
High-pressure gauge reading is below normal. For normal operating pressures, refer to Table 1. Note: Ambient temperature is above 21°C (70°F).
The air flow to the operator's compartment is very cold, or the air flow may be restricted completely at times. Probable Cause
The thermostat switch is held closed. There is a short in the wire to the magnetic clutch. The magnetic clutch will not release.
Check the wire that goes to the magnetic clutch. The wire may
