11
Furnace control board status LED shows code 11 (one short flash, one long flash) and burner will not ignite.
No Previous Code / Control Reset Indication
12
Status LED shows code 12 (one short flash, two long flashes) after a call for heat; furnace may or may not complete a cycle.
Blower On After Power Up / Low Heat Demand Memory
13
Status LED flashes code 13 (one short, three long). Furnace may lock out or shut down early in the cycle.

Status LED flashes code 14 (one short, four long). Furnace attempts to start but shuts down and may lock out after several tries.
Ignition Lockout / Ignition Failure
21
Status LED flashes code 21 (two short, one long). Furnace may not respond to thermostat or may behave erratically.
Gas Heating Lockout or Control Fault (varies by board revision)
24
Status LED flashes code 24 (two short, four long). Furnace does not respond to thermostat; no inducer or blower operation.
Secondary (24V) Fuse Open / Low-Voltage Short
31
Status LED flashes code 31 (three short, one long). Inducer may run but burners do not light; furnace may shut down after a few attempts.
Pressure Switch Did Not Close or Opened
32
Status LED flashes code 32 (three short, two long). Furnace may overheat and shut down; blower may not start on time.
Low Heat or Blower Fault / Blower Failure to Start
33
Status LED flashes code 33 (three short, three long). Furnace starts but shuts down on limit; blower may continue to run.
Limit or Flame Rollout Switch Open
34
Status LED flashes code 34 (three short, four long). Furnace attempts ignition but flame is weak or goes out quickly.
Ignition Proving Failure / Weak Flame Signal
41
Status LED flashes code 41 (four short, one long). Blower may run at incorrect speed or not at all; airflow may be low.
Blower Motor Fault (ECM or PSC) / Blower Out of Range
42
Status LED flashes code 42 (four short, two long). Inducer or blower may run unexpectedly; furnace may not heat properly.
Inducer or Blower Fault / Reversed Polarity or Ground Issue
43
Status LED flashes code 43 (four short, three long). Furnace may short-cycle or fail to maintain temperature.
Low Heat or High Heat Pressure Switch Fault (Two-Stage Models)
44
Status LED flashes code 44 (four short, four long). Furnace may lock out or fail to complete a heating cycle.
Secondary Limit or Auxiliary Limit Open
45
Status LED flashes code 45 (four short, five long). Furnace may shut down and require power reset to restart.
Control Board Lockout / Hard Lockout
Symptom
Burners light but go out after a few seconds; furnace retries several times then stops heating.
Flame Sensing Failure
Symptom
Furnace frequently trips the household circuit breaker.
Overcurrent / Electrical Short
Symptom
Furnace makes high-pitched squealing or screeching noises during operation.
Blower Motor or Inducer Bearing Wear
Symptom
Furnace operates but there is noticeable cold air infiltration or drafts near registers when the system is off.
Backdraft or Infiltration Through Ducts
Symptom
Furnace produces heat but airflow from registers is weak; some rooms are cold.
Insufficient Airflow / Duct or Blower Restriction
Symptom
Furnace rattles, vibrates, or makes banging noises when starting or stopping.
Cabinet Vibration / Duct Expansion Noise
Symptom
Furnace runs but carbon monoxide detector in the home alarms during operation.
Flue Gas Spillage / Possible Heat Exchanger or Venting Problem
Symptom
Furnace runs but house never reaches set temperature; supply air feels only mildly warm.
Low Heat Output / Underfiring
Symptom
Furnace runs but makes loud booming or delayed ignition noises when burners light.
Delayed Ignition / Burner Flashback
Symptom
Furnace starts and heats, but shuts off before reaching thermostat setpoint; frequent on/off cycling.
Short Cycling Due to Overheating or Oversizing
Symptom
Furnace starts and stops repeatedly within a minute or two; thermostat display may flicker or reset.
Low-Voltage Power Interruption / Transformer Overload
Symptom
Furnace will not start at all; no inducer, no blower, no LED lights on the control board.
No Power to Furnace
Symptom
Indoor blower runs continuously even when thermostat is not calling for heat or fan.
Blower Stuck On
Symptom
Inducer motor runs but burners do not light; after several attempts, furnace shuts down.
Ignition Failure Without Displayed Code
Symptom
Outdoor PVC vent or intake on a high-efficiency Payne furnace frosts or ices up in cold weather.
Vent Termination Icing / Restricted Combustion Air
Symptom
Rust-colored water or staining around the furnace or in the burner compartment.
Condensate Leakage onto Heat Exchanger or Burners
Symptom
Strong burning, chemical, or electrical smell when the furnace runs.
Odor from Dust, Overheating Components, or Contaminants
Symptom
Thermostat calls for heat but furnace does nothing; control board LED is on solid, but no inducer or blower starts.
No Heat Call Recognized / Thermostat Circuit Fault
Symptom
Thermostat shows heat is on, but furnace cycles between heating and blowing cool air.
Intermittent Limit Trip / Overheating and Cooling Cycle
Symptom
Water leaking around the base of the furnace or from PVC venting on a high-efficiency Payne furnace.
Condensate Drain or Trap Blockage
