1. Hold 62 is momentarily displayed prior to burner ignition during the Drive to Lightoff.
2. Check Fuse "A", blown fuse prevents blower from operating.
3. Inspect blower wiring, ensure connectors at Sola controller and blower are securely attached.
4. If Hold 62 persists for 15 seconds or more, while the blower is running, check "Fan speed" indicated on display. If "LOW RPM", "HIGH RPM", “0” or rapidly changing RPM value is displayed, try connecting another Sola controller. If problem remains, replace blower.
