Fisher & Paykel WA37T26EW Service Manual page 15

To test all windings you will need to measure across:
• Red & Blue
• Red & Yellow
• Blue & Yellow
If the meter shows an incorrect reading we would then recommend testing the stator from
underneath the machine as there could be a fault in the wiring harness. To test the stator, remove
the rotor and stator. Refer to Sections 8.17 and 8.18.
Note: Two clamp plates are used to secure the Stator, one on each side. The four bolts are
tightened to a torque of 5Nm. The plastic bolt for securing the Rotor requires a 16mm
socket and should be tightened to 8Nm.
After removing the Stator, it can now be tested.
Test points are:
R (Red) / B (Blue)
B (Blue) / Y (Yellow)
Y (Yellow) / R (Red)
The value should be approx. 39Ω +/- 10%
across any of the two windings.
3.8.2 Rotor
The rotor is also unique to this machine. It has 48 blocks of individual magnets in a black
moulding.
The rotor is not interchangeable with any previous phase or series of machine.
The rotor can physically be interchanged, however electrically they are incompatible.
The photograph below shows the Rotor used.
