New Holland NH 4111 – Armrest Controller: Rear Remote No.1 Potentiometer Faulty

The electronic control system is receiving an invalid signal, an out-of-range voltage, or no signal at all from the potentiometer responsible for monitoring the position or flow control of the #1 electro-hydraulic rear remote valve.

1. 1

   Inspect the wiring harness and connectors between the remote valve #1 lever in the armrest and the Armrest Controller for damaged pins, corrosion, or loose connections.

2. 2

   Perform a component swap test by swapping the electrical connection of the Remote No.1 lever/potentiometer with another working remote (such as Remote No.2). If the fault code changes to the corresponding remote (e.g., NH 4114/4115 for Remote No.2), the potentiometer itself is faulty. If the code remains NH 4111, the issue is likely in the wiring harness or the controller.

3. 3

   Attempt to clear the fault code and perform a lever calibration through the tractor's A-post instrument display. If the potentiometer has failed, the calibration will not complete successfully.

1. 1

   Power down

   Turn off the tractor and disconnect the battery to prevent electrical shorts during service.

2. 2

   Access the armrest

   Remove the retaining screws and lift the cover of the armrest console to access the electro-hydraulic remote levers and flow control knobs.

3. 3

   Disconnect the faulty potentiometer

   Locate the potentiometer assembly for Remote No.1. Carefully unplug its electrical connector from the armrest harness.

4. 4

   Remove the component

   Remove the retaining nut (often a 3/8-32 nut) or mounting screws holding the potentiometer/lever assembly in place and extract the faulty unit.

5. 5

   Install the new part

   Insert the replacement potentiometer, secure it with the retaining hardware, and plug in the electrical connector.

6. 6

   Reassemble

   Reinstall the armrest console cover and reconnect the tractor's battery.

7. 7

   Recalibrate

   Power on the tractor. You must perform a lever calibration procedure through the A-post display so the controller can learn the sweep and neutral positions of the new potentiometer.

8. 8

   Clear codes

   Clear the NH 4111 fault code from the system and test the #1 rear remote for proper operation.
