Instruction manual

2) Check that the starting winding is not shorted
to ground. There should be no continuity
between W or Z and the control box casing
(Figure 712). If the connection is shorted, the
stator must be replaced.
3) With an ohm-meter, measure resistance of
the run winding U/V by placing the test
probes on position 4(U) and position 5(V) of
terminal board M1 (.93 ohms is normal
Figure 713, shows 2.2-0.2 = 2.0 ohms). This
is found on the wiring diagram #34427. If the
connection is open, the stator must be
replaced.
4) Check that the run winding is not shorted to
ground. There should be no continuity
between U or V and the control box casing
(Figure 714). If the connection is shorted, the
stator must be replaced.
7-6 Fuse Check, F1 {Code #22366 (110V), Pos.
11, Code #21076 (220V), Pos. 13}
1) With an ohmmeter, check continuity by
placing the test probes on X1 and X2 of the
fuse. If no continuity is found, replace the
fuse with the spare by lifting the grey fuse
holder (Figure 715).
7-7 Thermal Protector Check
With the ohmmeter, place the test probes on the
fuse terminal and X1 of the grey terminal board
where the two small wires are fixed (Figure 716
on the next page). If the connection is open, the
stator must be replaced.

NOTE:
The thermal protector opens when the motor is hot
in order to prevent damage. It is normally closed
and automatically resets.
