The most common root cause identified by field technicians is a strict calibration window for the neutral position. If an operator releases the drive butterfly valves or lift switches, the controller expects the voltage to return to a highly precise baseline. If the components are slightly misaligned, or if environmental factors (like temperature changes) alter the sensor outputs, the machine registers the baseline position as "active" or out-of-range, triggering the error code. 2.

Below is a detailed guide on what causes this code and how to fix it to minimize warehouse downtime. What Causes Error Code 4372?

: Operators frequently note that cycling the key switch temporarily clears the code. However, as soon as the control handle is moved or a direction is picked, the error resurfaces. Root Causes of the Fault

Less common, but a failing main logic controller can misinterpret valid sensor signals.
If firmware and drying do not work, the sensor on the print card itself may be faulty.
, meaning the tiller’s position or inputs do not match expected values. 1. Immediate Action & Cause Neutral Zone Error
Ensure the tiller handle and all control buttons (butterfly switches) move freely and are not physically stuck or gritty.
