Full Diagnosis

230VAC Over Voltage Event. 230VAC over-voltage event detected.

All Recorded Causes

Measure supply voltage at outdoor unit. Check for utility overvoltage condition. Inspect for open neutral on single-phase supply. Contact utility company if supply voltage is consistently high. Board retries after 15 minutes.

Verify Before Replacing Parts

  1. Confirm the exact Bryant model family and air conditioners context before acting on a generic code description.
  2. 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.
  3. Inspect connectors, relay outputs, and any recently replaced electrical parts for mismatch or loose fit, and verify check for utility overvoltage condition.
  4. After the correction, run the system long enough to confirm the air conditioners fault does not return under normal load.
