Pressure switch Do not disconnect the pressure hose
from pressure switch to perform
measurements.
Measure resistance across the
following terminals on the pressure
switch:
Terminal 1 to 2
Terminal 1 to 3
Refer to wiring diagram/schematic for
correct contacts.
Air pressure that actuates switch is
determined by the water level of the
tub.
