Replacing the Evergreen EM
If the motor does not operate with proper High Voltage Power and low
voltage communication present at the motor, it is failed and will require
replacement. Before replacing the motor, please call the Contractor
Hotline to confirm your diagnostics if possible. The Evergreen EM is a single
component replacement. The control cannot be replaced separately from
the motor. Contact the distributor where the motor was purchased or any
authorized Evergreen distributor for replacement.
