Light off rate proving failed.
1. Blower is not turning on.
2. Missing or incorrect blower feedback signal
3. Blower is always on.
4. Incorrect Sola controller.
1. - Blower power disconnected; Verify that the 3-position Molex connector on the wiring harness is securely connected to its mating connector on the blower.
- Blown fuse; Check Fuse "A" using the procedure described above. Fuse "A" protects the blower as well as the ignition spark generator and appliance pump.
- Faulty blower; Measure voltage across pins 1 & 2 (black and white wires) of 3-position connector on wiring harness. If 120VAC detected, replace power connector and remove 5-position signal connector. Blower should rotate at high speed. If blower does not rotate, replace blower.
2. Check error code "Hold 62"
3. - Blower signal cable disconnected; Verify that the 5-position Molex connector on the wiring harness is securely connected to its mating connector on the blower. Check that the 4-position Molex connector on wiring harness is securely connected to its mating connector on the Sola controller.
- No 24VAC to Sola controller; Check Power LED on Sola controller. Check Fuse "C". With an AC voltmeter measure voltage at terminals J8 1 & 2, 24VAC should be present.
4. Replace control with correct model.
