Carrier Furnace Error Codes: Diagnostic Guide
Modern Carrier furnaces flash two-digit codes: short flashes give the first digit, long flashes the second. Codes vary by model, so the chart on your furnace door is the authoritative reference.
| Code | Meaning | Typical Fix |
|---|---|---|
| 13 | Limit circuit lockout - repeated overheating | Check air filter, supply vents, and duct restrictions |
| 14 | Ignition lockout - gas supply, igniter or flame sensing problem | Confirm the gas valve is open and power-cycle once; call a technician if it returns |
| 31 | Pressure switch did not close - inducer or venting issue | Check outdoor vent pipes for snow or ice; otherwise call a technician |
| 33 | Limit or rollout switch open | Replace air filter; call a technician if it repeats or a rollout switch has tripped |
| 34 | Ignition proving (flame sense) failure | Requires a technician: flame sensor, gas pressure or burner problem |
| 41 | Blower motor fault | Requires technician diagnosis |
| 42 | Inducer motor fault | Requires technician diagnosis |
| 45 | Control board fault | Control board failure - requires professional replacement |

Carrier Furnace FAQs
Is Carrier a good furnace brand?
Yes - Carrier is one of the oldest and most respected HVAC brands, founded in 1915. Their Infinity series furnaces are among the best available. Build quality and efficiency are excellent, though parts can be more expensive than budget brands.
What does code 13 mean on my Carrier furnace?
Code 13 (1 short flash, then 3 long flashes) is a limit circuit lockout - typically caused by overheating. The most common cause is a clogged air filter. Replace your filter first; if the fault persists, the limit switch may need replacement.
How long does a Carrier furnace last?
A well-maintained Carrier furnace typically lasts 15 to 20 years, and up to 25 with good maintenance. Their Infinity and Performance series hold tighter tolerances than budget brands. Annual maintenance significantly extends lifespan.
