John Deere 200152 – E04: Cleaning Fan Speed Failed to Reach Commanded Speed

The cleaning fan speed did not reach the commanded target speed within a 130-second timeframe. This indicates a potential issue with the mechanical, electrical, or hydraulic systems responsible for controlling or operating the cleaning fan, preventing it from achieving its required RPM.

1. 1

   Visually inspect the air intake screen, fan blades, and ducting for any visible obstructions or debris.

2. 2

   Examine the fan blades for any damage, wear, or bending.

3. 3

   Check the tension and condition of the fan drive belt, as a loose or worn belt can cause the fan to run at a lower speed.

4. 4

   Inspect the fan bearings for any wear or play.

5. 5

   Check the hydraulic fluid level, verify hydraulic pressure is within specifications, and inspect for leaks in the fan motor or hydraulic lines.

6. 6

   Check if the fan speed actuator motor has stopped due to its thermal shutoff (allow 10-15 minutes to cool if used continuously or if linkage is binding).

7. 7

   Inspect the electrical harness and connections to the fan speed actuator for any damage or loose connections.

1. 1

   Clean components

   Remove any debris or blockages from the air intake, fan, and associated ducting.

2. 2

   Address belt issues

   If the fan drive belt is loose, adjust the tension according to specifications. Replace the belt if it is cracked, worn, or damaged.

3. 3

   Hydraulic system repairs

   If a hydraulic issue is identified (low pressure or leaks), consult the service manual or dealer to repair or replace a faulty hydraulic pump or motor.

4. 4

   Replace damaged fan components

   If the fan blades are damaged or the assembly is out of balance, replace the fan assembly.

5. 5

   Replace the fan speed actuator

   If diagnostic checks point to a faulty fan speed actuator, replace it.
