TEST PROCEDURE
Test all input and output
connections to board.
Set the ohmmeter to
R x 1.
Connect the meter leads
to the switch terminals,
and measure the conti-
nuity when the switch is
turned ON and OFF.
Set the ohmmeter to
R x 1.
Connect the meter leads
to the thermostat termi-
nals, and measure the
continuity when the
switch is heated above
104˚F, and then cools to
below 104˚F.
Set the ohmmeter to
R x 1.
Connect the meter leads
to the thermostat termi-
nals, and measure the
continuity when the
switch is heated above
395˚F, and then cools to
below 395˚F.
Set the ohmmeter to
R x 10.
Connect one of the
meter leads to circuit
board pin J1-1.
Connect the other meter
lead to circuit board pin
J1-8.
