Full Diagnosis
Ignition Lockout. Control auto-resets after 3 hours after repeated ignition-proving failures.
All Recorded Causes
Check gas supply pressure and valve operation. Inspect ignitor for cracks or contamination. Verify flame sensor signal and clean sensor rod. Check for proper venting and combustion air. Control auto-resets after 3 hours.
Verify Before Replacing Parts
- Confirm the exact Bryant model family and furnaces context before acting on a generic code description.
- Walk the entire heating sequence in order instead of jumping straight to the reported code, watching for check gas supply pressure and valve operation.
- Verify each safety device and prove where the sequence stops under live operation, including whether inspect ignitor for cracks or contamination.
- After the correction, run the system long enough to confirm the furnaces fault does not return under normal load.
