Bryant/Payne Furnace Error Codes Guide
Bryant and Payne are both United Technologies brands built on the same platform as Carrier furnaces. Their fault code systems are nearly identical, though model numbers differ. If your Bryant Evolution, Preferred, or Legacy furnace — or your Payne PG8M or PG9M — is showing a fault, this guide will help you decode it and know exactly what to do next.
Reading Bryant/Payne Flash Codes
The LED status light on Bryant and Payne furnaces blinks in a pattern that indicates the specific fault. Count the flashes, note the pause, then count the second set if applicable. A legend sticker inside the furnace door maps these patterns to specific fault descriptions. Bryant Evolution series with Infinity Touch Control display alphanumeric fault codes directly on the thermostat screen and keep a fault history log.
Common Bryant/Payne Furnace Fault Codes
| Flash Code | Meaning | What to Do |
|---|---|---|
| 1 flash | Ignition lockout — failed 3 ignition tries | Check gas; one manual reset allowed |
| 2 flashes | Pressure switch fault — stuck open | Inspect flue and condensate for blockage |
| 3 flashes | Pressure switch fault — stuck closed | Technician required |
| 4 flashes | High-limit device open — overheating | Replace air filter; ensure all vents open |
| 5 flashes | Flame sense with no gas valve call | Technician required — gas valve concern |
| 6 flashes | Wiring fault — reversed 115V polarity | Licensed electrician required |
| 7 flashes | Gas valve fault | Technician required |
| 8 flashes | Low flame signal — dirty or failing sensor | Clean flame sensor or call for service |
| 9 flashes | Rollout switch tripped | Shut off furnace; call immediately |
| Slow steady | Standby — no call for heat | Normal operation |
| Off | No power to control board | Check breaker and power switch |
Bryant Evolution vs. Preferred vs. Legacy Series
The Evolution series uses a communicating control system. Faults are displayed on the Infinity Touch Control thermostat and logged for technician review. These systems can also generate detailed performance data that helps technicians identify developing issues before they cause failures.
The Preferred series uses standard LED blink codes and is compatible with most programmable thermostats. Diagnostic information is more limited than the Evolution series.
The Legacy series (and Payne models) uses the same basic LED blink code system. These are straightforward single-stage or two-stage furnaces with conventional controls.
What Homeowners Can Check
Air filter (4 flashes): Bryant and Payne recommend checking the air filter every 30 days during heating season. A clogged filter is the leading cause of high-limit trips. Replace with the correct size and rating.
Flue termination (2 flashes): Walk outside and inspect where the PVC flue pipes exit the house. Clear any ice, debris, or bird nests from the termination caps. This is especially important after snowstorms.
Power supply: If the LED is dark, check the furnace circuit breaker and the power disconnect switch near the unit.
Thermostat: Confirm the thermostat is set to HEAT mode and the setpoint is above the current room temperature. On Evolution systems, check that the wiring harness connecting the thermostat to the furnace is fully seated.
When to Call a Professional
Rollout switch trips (9 flashes) require immediate attention — do not attempt to restart the furnace until the cause has been identified and corrected by a technician. Gas valve faults (7 flashes) and flame-sensed-without-call codes (5 flashes) are also technician-only territory.
For Bryant Evolution communicating systems, diagnostic accuracy is significantly better when a technician uses Carrier's Service Assistant software to read the fault log. Manual LED code reading is not available on all Evolution faults.
