Possible Causes
Failed enclosure fan motor, Blocked fan intake/exhaust, Faulty fan relay, Broken fan blades
How to Fix / Troubleshooting
Safety first: Turn OFF the generator and disconnect the battery. Allow the unit to cool before working near the fan.
- Inspect fan area: Remove debris, leaves, or nests from the fan intake and exhaust grilles.
- Check fan blades: Ensure the blades are intact and not rubbing against the housing.
- Test fan operation: With the generator running (if safe) or by applying 12 V directly (advanced users), verify the fan motor spins. If not, the motor or relay is likely faulty.
Replace the enclosure fan assembly with the correct Pulsar part if it fails to operate.
