Possible Causes

Clogged air vents causing higher internal temperature, Failing fan bearings, Temperature sensor reading too high, Firmware controlling fan stuck in high-speed mode

How to Fix / Troubleshooting

Safety first: Fans may start unexpectedly; isolate power before opening the unit.

  • Step 1 – Clean vents: Gently clean dust from all external vents with a dry cloth or low-pressure air.
  • Step 2 – Check ambient temperature: Ensure the charger is not installed in a confined or hot space.
  • Step 3 – Inspect fan: With power OFF, open the charger and check the fan for obstruction or wobble. Spin it by hand to feel for roughness.
  • Step 4 – Replace fan: If noisy or stiff, replace the Jaguar-specified cooling fan.
  • Step 5 – Sensor/firmware: If a new fan still runs continuously, the temperature sensor or firmware may be misreading; update firmware or replace the sensor/PCB as needed.
