Possible Causes
Blocked or dirty blower wheel, Failing indoor fan motor bearings, Faulty DC fan motor, Faulty indoor PCB fan drive circuit
How to Fix / Troubleshooting
Safety first: Isolate power before opening the indoor unit.
Steps:
- 1. Clean blower and filters: Remove heavy dust buildup from the cross-flow fan and filters using a soft brush and vacuum.
- 2. Check for obstructions: Ensure no wiring, insulation, or foreign objects are rubbing on the fan.
- 3. Spin test: Rotate the blower by hand; it should move freely. If stiff or noisy, the motor may be failing.
- 4. Inspect motor connector: Confirm the fan motor plug is fully seated on the PCB.
If H30 persists, the indoor fan motor assembly or indoor PCB will likely need replacement by a technician.
