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.
