If you encounter this code, troubleshooting should follow these steps:
In the hierarchy of Jungheinrich diagnostics, the 4000-series codes typically relate to specific sensor and controller communication issues. Code 4372 specifically points toward an anomaly in the —often indicating a short circuit, a break in the wiring, or a sensor reading that is out of plausible range.
If updating the firmware doesn't resolve the issue or isn't possible at the moment, the problem might be physical. jungheinrich eje 120 error code 4372 work

A: Rarely. Jungheinrich has issued updates for overly sensitive voltage thresholds on some EJE 120 firmware versions (e.g., from v3.2 to v3.4). However, this masks the problem. Always fix the hardware first.
If the hardware itself is faulty, the entire tillerhead assembly may need replacement.
Specialised services, such as EKT TEKNOLOJİ , offer repair and revision services specifically for Jungheinrich E4372 fault codes, which may involve repairing the internal control boards or cards.
