First, remove the blower pipe from the top of the blower, this may
require the removal of a single screw penetrating through the blower housing,
or a pipe clamp. Then remove the screws holding the base of the blower to the
spa. Note, that if the attachment base is made of metal, and the screws
are rusted through, you may have to destroy the screws using a hammer and a
chisel, or drill, or by other alternative means in order to get the blower out
of the spa skirt.
|
| Now, with the blower removed, put it on a work surface that is
suitable to you, this could be the floor or a work bench. |
 |
 |
Using a 5/16" or 1/4" inch nut driver (or other appropriate
tool), remove the 4 screws that are holding the top half of the blower housing
to the lower base. |
| Once the screws are removed, separate the two halves of the blower
assembly. This may require a certain amount of force, especially if their
is corrosion or rust built up between the components. In this particular
example, we can see what caused this blowers demise... which is typically,
water, and corrosion. |
 |
 |
If the blower motor won't separate easily from the top part of the
assembly, (which is typical), using a screwdriver to pry it out of the top of
the housing usually works ok. |
| This is most likely what you will see.... Go ahead and separate
the motor from the shell, being careful not to stretch the power wires too
much. At
this point, it may be required to remove the power cord strain relief to allow
enough room in the electrical cord to remove the blower motor
further.
Now is a good time to wipe the
blower internal surfaces clean.
|
 |
 |
At this point, you should see the three wires and where they connect
to the blower motor. They will (should be) colored Black, White, and
Green. Cut the
wires on the power cord on the input wire side of the wire nuts (wire
connectors).
If the green ground connector
is not corroded, it can be re-used. Remove it from the blower motor using
a nut driver, and attach it to the new one in the same place.

|
| Strip and connect the power
wires together, being careful to separate and insulate them
properly. My
preferred procedure is to connect the wires using wire nuts, then wrap the wire
nuts and the wires together using electrical tape. This prevents the wire
nuts from spinning off in the blower. Then I use a nylon tie wrap to
secure all of the wires together and to keep the electrical tape from
unraveling.
|
 |
 |
Once that is complete, push the blower motor into the top half of the
housing. Then, pull out the excess cord from the top of the housing and
reassemble the strain relief in the housing to retain the power cord. If
you didn't have to use any more cord to attach the power wires than was
required by the original motor, then the strain relief should be used in the
original position on the cord as when it was removed. |
| Reassemble the
blower housing using the original screws. Then VISUALLY inspect the wiring from
the blower exhaust to ensure that the wiring doesn't interfere with any part of
the armature (moving part) of the motor.
|
|
|
The next step
is to remount the blower and reattach the blower pipe as it was originally
installed.
Next, I make sure everything in
the vicinity is dry, so as to prevent electrocution, then plug the blower back
into the spa control and test for proper operation. |
