Furnace LED shows code 55; indicates no previous fault stored in memory.

Note: Code 55 on many Bryant furnaces is informational and does not indicate an active fault.

• Check current operation: If the furnace is heating normally, no action is required.
• Observe for new codes: If you are troubleshooting an intermittent issue, leave the furnace running and check later for any new stored codes.

If the furnace is not operating but only shows 55, verify thermostat settings, power, and door switch engagement.
