PHASE ANGLE WINDING TEST
12. Test with an AC voltmeter for approximate-
ly 66VAC at each phase winding. Test
leads #201, #202, #203, and #204 per
Table F.1.
For control board #G2206, see
Figure F.9
for lead locations.
For control board #G1575, see
Figure F.10
for lead locations.
NOTE
: If the main input supply voltage
varies, the main transformer voltages will
vary proportionately.
a.
If the voltage is low, remove the plug or
leads and recheck the voltage for
66VAC. If the reading is normal, the
control board may be faulty. Replace
the control board.
b.
If one or more of the voltage tests are
incorrect, check for loose or faulty
wiring.
c.
If the wiring is good, then the main
transformer may be faulty. Replace the
main transformer.
