Full Diagnosis
230VAC Dropout-Reset Event. 230VAC dropout/reset event detected; control reverts to 5-minute cycle delay.
All Recorded Causes
Measure supply voltage at outdoor unit. Check for intermittent power supply issues. Inspect disconnect and wiring for loose connections. Contact utility if voltage dropout is from supply. Control reverts to 5-minute cycle delay.
Verify Before Replacing Parts
- Confirm the exact Bryant model family and air conditioners context before acting on a generic code description.
- Start with line voltage, low voltage, and board output checks in sequence so the fault is isolated cleanly — the data plate flags measure supply voltage at outdoor unit.
- Inspect connectors, relay outputs, and any recently replaced electrical parts for mismatch or loose fit, and verify check for intermittent power supply issues.
- After the correction, run the system long enough to confirm the air conditioners fault does not return under normal load.
