Possible Causes
Failed cooling fan motor, Blocked fan blades, Disconnected fan power connector, Faulty fan driver circuit on control board
How to Fix / Troubleshooting
Safety first: Turn off power before touching the fan or opening the housing. Moving fan blades can cause injury.
- 1. Listen for fan operation: During charging, you should hear the internal fan on fan-equipped Primecom models. No sound or unusual noise indicates a problem.
- 2. Inspect vents: Check that intake and exhaust vents are not blocked by dust, spider webs, or debris.
- 3. Internal inspection (technician): With power off, open the housing and visually inspect the fan. Spin the blades gently by hand; they should move freely without grinding.
- 4. Check fan connector: Ensure the fan's power connector is firmly seated on the control board.
- 5. Replace fan or board: If the fan is seized or does not run when powered, replace the fan assembly. If a known-good fan does not operate, the fan driver circuit on the main control board may be defective and require replacement.
