When making the ground test,
if the needle goes clear to zero
the motor probably has a wire
touching the stator at some
point and the stator will have
to be replaced.
Winding resistance test. If
motor shows a satisfactory
ground test, then the winding
resistance must be checked.
Use ohmmeter with scale
pointer set on R X 1 scale. On
this scale meter reads directly
on ohms. Always check the
meter with leads together as
described above under ground
test before making a reading of
the winding.
Connect one meter lead to each
of the black terminal leads.
Meter should read about 1.9
ohms. This is the resistance
of the main winding for a 115
volt stator. This reading for
a 230 volt stator should be
about 7.7 ohms.
Now remove the capacitor and
connect one meter lead to each
of the brown wire terminals.
The meter should read about
12 ohms for a 115 volt stator.
For a 230 volt stator this
reading should be 21.3 ohms.
This is the resistance of the
start winding.

7. Remove the stator. To remove
the stator, remove the four
hex
head
screws
disconnect the brown capacitor
leads from the capacitor and
remove the stator plate with
the capacitor. Lift the stator off
the seal plate (8) and set aside.
8. Remove the impeller. To
remove the impeller (10),
hold the motorshaft (5) with a
screwdriver at the center of the
impeller and tap the impeller
with a plastic or rubber mallet
so as to turn the impeller
counterclockwise.
9. Check
the
seal.
the rotating portion of seal
(6) from shaft by inserting a
screwdriver under the edge
of the seal and lifting it off.
Inspect the seal face for any
nicks or an uneven seating of
seal face. If any are present,
replace the seal.
