Discharge Pressure Switch - GE GEH Series Service Manual

Discharge Pressure Switch

The discharge pressure switch is an
additional safety device for the sealed
system, backing up the T4 compressor
outlet sensor.
The normally closed switch is designed
to open the compressor circuit if the
discharge pressure exceeds 400 psi.
It will reset once the pressure drops
below 300 psi.
If the switch opens within 1-2 minutes
of compressor start up, check for a
sealed system restriction.
