Error code: Lockout 122

Cause of error code Lockout 122

1. Blower is not turning on. 
2. Missing or incorrect blower feedback signal

Solution for error code Lockout 122

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.
