Spin the motor’s shaft. Spin briskly, but only by
hand. The three phase LED’s should all glow, and
with about the same brightness, until the shaft slows
down. The relative brightness will vary; the 3/4 and 1
HP models will be the brightest, the 1/3 and 1/2 HP
models will be somewhat dimmer. Uneven
brightness between LEDs or not all three LED’s
being lit indicate a winding problem; replace it.
If everything works well to this point, do a final test.
First, press the Battery Check position on the switch.
The Red LED should light. If not, replace the battery.
Now, press the Short Test position on the switch. NO
LED should light. If any LED does light, it is an
indication that there is a short between that winding
phase and the frame of the motor, creating a
dangerous condition. (No spinning in this test.)
If none of the tests on these two pages indicate a
winding section problem, you now have a clear
conclusion: if the motor does not operate, but the
winding section checks out fine, then the problem
must be in the module section.
When a winding problem is discovered, most unit
manufacturers recommend replacing the entire
motor; modules can be adversely affected when
windings fail. The reverse is not usually true: If a
module fails, it usually does not affect the winding
section, making for an easier and less costly repair.

Our website (www.ZebraHVAC.com) has short
tutorial videos for the SideWinder tool and
each adapter and accessory.
Since the number of available adapters is
expected to increase in the future, we
encourage you to use our website regularly to
get information about new accessories and
adapters for the SideWinder system.
At the time of printing, the standard plug on the
SideWinder’s harness fits about 85% of all
ECM motors, including most made by GE,
Genteq, Evergreen, and Regal-Beloit.
Two other adapters are now available to fit
Emerson’s ECM’s (ZSWAE) and Broad
Oceans ECM’s (ZSWAB).

Avoiding Problems & Help
Remember that this tool is designed to help
you determine which portion of an ECM Motor
is having problems. It is important to first
determine if the motor (or some other
component) is at fault. Specific tools, some
made by ZebraHVAC, are available to isolate
those system problems. Once a problem is
confirmed to be in the motor, this tool should be
used to further isolate which specific section of
the motor - the module or the winding section -
is causing the fault. Many unit manufacturers
indicate that a very high percentage of ECM
motors returned to them have either “No
Problem Found” or the only problem found is in
the less expensive module section. Like the
introduction of emission control systems on
cars and trucks, ECM’s and other devices are a
part of our future HVAC systems. As
Technicians, we have to understand and use
the best available diagnostic tools to make
correct decisions about these systems.
ZebraHVAC has been at the fore-front of
helpful, diagnostic tools to assist you in your
career. Please let us know about issues and
suggestions to make your profession the most
respectable in the industry.
