A half‑blown H‑bridge triac lets the motor run only “up” or “down,” never both.
In our recent diagnosis, we identified that one half of the H-bridge triac pack had failed. This type of failure prevents the motor from operating efficiently, as it can only run in one direction—either “up” or “down”—but not both. This limitation can significantly affect the functionality of systems that rely on bidirectional movement.
To address this issue, we took the following steps:
1. Replacement of Drivers: We first replaced the drivers associated with the H-bridge to ensure that any potential underlying issues were resolved. This step is crucial as it helps optimize the performance of the motor and prevents further complications.
2. Testing Bidirectional Lift: After replacing the drivers, we conducted thorough testing to confirm the motor's ability to operate bidirectionally under load conditions. We verified that it could lift up to 200 lbs, ensuring that the repair was successful and the motor was functioning as intended.
Our repair
To fully restore the system's capabilities, we recommend replacing the entire triac pack. This ensures that all components are in optimal condition, providing reliable performance moving forward.
