Ensure power is isolated before
conducting test
Using a multimeter on the x1 resistance
scale, measure across the two terminals
on the defrost switch. The reading should
be less than 1 ohm.
Warning – ‘Live’ equipment Personal
Protective Equipment should be worn
when conducting this test.
Using a multimeter on the AC voltage scale,
measure across the load terminal on the
time delay switch and Line 2 on the
compressor contactor. Normal voltage is
240 volts.
Test 17 Test 18
Warning – ‘Live’ equipment Personal
Protective Equipment should be worn
when conducting this test.
Using a multimeter on the AC voltage
scale, measure across Load 1 and Line 2
terminals on the compressor contactor.
Normal voltage is 240 volts. Then
measure across Load 2 and Line 2
terminals on the compressor contactor.
Normal voltage is 0 volts.
Note: Control board must be calling for
heat for this test.
Ensure power is isolated before
conducting test
Using a multimeter set on the resistance
scale, measure across Load 1 and Load 2
terminals on the compressor contactor (run
winding), and across Load 1 terminal on the
compressor contactor and the yellow wire
on the capacitor (start winding).
Normal resistance for the run winding is 1.2
ohms. Normal resistance for the start
winding is 2.7 ohms when the compressor is
cold.
