Open start-circuit lockout. The open start circuit was detected 4 times, with a 5-minute delay between each detection. The compressor and outdoor fan are off.
Likely causes
- Compressor start winding is open
- Failed run capacitor
- Faulty run-capacitor wiring
- Compressor not wired to the control, or other faulty compressor wiring
Safe checks for L6
- Write down L6. The single open-start trip is 06. L6 is the lockout after four detections
- Techniciancheck the compressor, the run capacitor, and the wiring. The chart says this lockout must be cleared by cycling 24 VAC to the control
Capacitors can hold a charge after the power is off. Safety terms.
When to call a pro
Call a licensed HVAC technician. Do not keep resetting power to force another start. The chart already counted four detections.
