(1) Measure the insulation resistance between
BLUE lead and the core.
(2) Measure the insulation resistance between
WHITE lead and the core.
(3) Measure the insulation resistance between
YELLOW lead and the core.
(4) Measure the insulation resistance between
BROWN lead and the core.
White / Red = 0.2 Ohm
Black / Blue = 0.25 Ohm
Yellow / Yellow = 0.58 Ohm
Measure the insulation across one of the soldered
terminals of the rotor and the core
Then test across the 2 soldered terminals of the rotor.
Resistance = 1.75 Ohm
NOTE 1 :
Because a diode is soldered to the coil ends at
the terminals, resistance may be measured only
when tester probes touche the terminals in one
combination of polarity. Therefore, if no resistance
reading appears, try checking in reverse polarity.
Diode rectifier test (Lovated between the 2 capacitors)
Orange wire should read to all of the other terminals.
Both Brown wires should read to the Brown White wire (Note polarity)
Those are pretty much the checks that you can do and should reveal where the problem lies.
I think you may have a burned wire / terminal somewhere inside the control panel.
Usually when they just stop working the failures are
1. The rotor (Bad and horribly expensive news)
2. Capacitor wires (Yellow) open
3. Stator wires damaged.
The stators on these units do not usually fail.
All manuals for this unit can be found here (Owner's / parts / Service)
