IF THE MOTOR IS NOT RUNNING
Check for proper high voltage and ground at the
5-pin connector at the motor. Correct any voltage
issues before proceeding to the next step. These
are dual voltage motors capable of operating in
120 or 240VAC systems. On 120VAC systems
there should be a jumper between terminals 1
and 2 (see Figure 1). On 240VAC systems the
jumper should be removed (see Figure 2). If a
motor is operating at 240VAC with the jumper in
place, the motor will be permanently damaged.
Input voltage within plus or minus 10% of the
nominal 120VAC or 240VAC is acceptable.
If the 2.0 / 2.3 / Eon
®
/ 3.0 motor has proper high
voltage and ground at the 5-pin connector, go
to the “Troubleshooting with the TECINspect
®
Service Tool” section on page 16. If the 2.5
motor has proper high voltage and ground at the
5-pin connector, the equipment manufacturer’s
checks, located in their service manuals, must be
referenced. This guide cannot troubleshoot the
communication to the 2.5 motor.
The TECINspect Service Tool is not designed
for use on the 2.5 motor.
If further troubleshooting identifies a failed control
module, go to “Replacing the ECM Control
Module” section on page 24 of this guide for
replacement steps.
