Alarm 136 — Outside Air Damper/ECON Mechanical Fault

What does Alarm 136 mean?

This alarm is triggered when the damper actuator does not move the damper to the target position within the predefined time, meaning the control voltage does not match the feedback voltage within the acceptable tolerance.

• Damper actuator is faulty.
• Mechanical binding of the damper.
• Low voltage supply to the actuator.
• Incorrect calibration of the damper.
• Wiring issue between the controller and the actuator.

Click steps to track your progress.

1. 1

   Check for any physical obstructions preventing damper movement.

2. 2

   Inspect the damper actuator for signs of damage or wear.

3. 3

   Verify the control voltage supplied to the actuator.

4. 4

   Ensure wiring connections are secure.

5. 5

   If the fault persists, the damper actuator or damper mechanism may need replacement.
