Using screwdriver, install the fan outlet on blower housing with five screws and flat washers.
CAUTION
Sheet metal screws are used to mount fan inlet ring. Take care that mounting screw holes
are not stripped.
14
Place blower in condenser housing and align holes.
15
Using screwdriver, secure motor side of blower housing with three screws and clamp.
16
Using screwdriver and wrench, secure blower housing bracket to condenser housing angle with
two screws, flat washers, and locknuts.
17
Install right end condenser cover. See WP0045.
18
Install front and top condenser covers. See WP0044.
TESTING
1
To test motor, disconnect P11 from J11.
2
Using multimeter check continuity between all J11 pins and motor housing. Continuity should
exist only on pin D.
3
Using multimeter, measure 3 phase windings at J11: A to B, B to C, A to C. All resistances
should be above zero, but less than 2 ohms.
4
Using multimeter, check J11. Pin D is ground. Check pins A, B, C, E, and F to pin D. There
should be no reading. Check pin D to motor frame, multimeter should read 0.
5
Using multimeter, measure resistance between pins E and F. Resistance should be zero meaning
the switch (S7) is closed.
6
Motor with shorted, open or grounded windings or open thermostatic switch should be replaced.
