Carrier 58STA090-1-16 90,000 BTU 80% AFUE Single-Stage Gas Furnace BLINK-1 Error Fix: LED 1 Blink — System Lockout (Retries Exceeded)

The furnace control board LED flashes 1 time, pauses, then repeats. This indicates the furnace has tried and failed to ignite or sense flame too many times and has entered a safety lockout. The system will not attempt another ignition cycle until manually reset. To reset: turn the thermostat to OFF for 30 seconds, then back to HEAT; or cycle the furnace power switch off and on. If the furnace locks out again after reset, there is an underlying problem — most commonly a dirty flame sensor rod (clean with fine emery cloth or steel wool), a failed hot surface ignitor, no gas supply (check that the manual gas shutoff valve is open and other gas appliances work), or a faulty gas valve. The 1-blink lockout code means the furnace already tried multiple ignition attempts (typically 3) and failed each time before locking out.
