If the contactor is burnt, replacing it is a relatively low-cost fix compared to a full controller.
Intermittent connections or damaged wiring between the tiller head and the main controller can lead to signal implausibility. jungheinrich eje 120 error code 4372
| Cause | Likelihood | Explanation | |-------|------------|-------------| | | High | The encoder (usually a resolver or Hall-based sensor) sends incorrect or intermittent signals. | | Loose or damaged encoder wiring | High | Chafing or poor contact in the encoder harness, especially near the motor or controller connector. | | Motor phase issue | Medium | A missing or imbalanced motor phase (e.g., bad contact in the motor cable plug). | | Controller hardware failure | Low-Medium | Internal failure in the drive controller (traction inverter). | | Worn drive motor bearings | Low | Mechanical play causes erratic encoder readings. | If the contactor is burnt, replacing it is
