Carrier status code 14: ignition lockout after four failed trials

What Does Error 14 Mean?

Status code 14 on this Carrier control is ignition lockout. The guide states that lockout occurs after four consecutive unsuccessful trials for ignition and that the control resets itself automatically after three hours. The number 14 therefore counts failures; it does not identify which part of the ignition sequence failed. Applies to: Carrier deluxe two-stage gas-fired induced-combustion furnaces with PSC or ICM blower motors, covered by troubleshooting guide 58-3T The count of four trials and the three-hour automatic reset are stated in Carrier troubleshooting guide 58-3T for deluxe two-stage induced-combustion furnaces. Single-stage and modulating Carrier controls, and the same number on other manufacturers, follow their own literature and their own retry counts. Owner-safe checks: Confirm that other gas appliances in the property are working normally, which separates a supply-wide interruption from a furnace-specific fault. | Check that the thermostat is calling for heat and that its batteries, if fitted, are good, so a failed call is not mistaken for a failed ignition. | Note the time of each lockout and the weather conditions, then leave the furnace off rather than forcing repeated retries. Qualified technician: Measuring gas pressure, testing igniter resistance, cleaning or replacing a flame sensor, and inspecting venting are licensed gas-furnace tasks. | A smell of gas at any point is an emergency. Leave the property, avoid switches and flames, and contact the emergency number for your gas supplier before anything else.
