| Code | Meaning |
|---|---|
| 13 | Limit circuit lockout — lockout occurs if the limit or flame rollout switch is open longer than 3 minutes, or (variable-speed Bryant wording) 10 successive limit trips occurred during high-heat. The control will auto-reset after 3 hours. Bryant's label cross-refers every 13 to code 33 for the diagnosis. |
| 24 | Secondary voltage fuse is open — the fuse protecting the control's 24-volt (secondary) circuit has opened because there is a short circuit in the secondary-voltage wiring. On the Evolution 987M the fuse is an automotive-type 3-amp fuse located on the control, and Bryant states the control LED will display status code 24 when the fuse needs to be replaced. |
| 33 | Limit circuit fault — a limit switch or flame rollout switch in the limit circuit is open. The blower runs for 4 minutes or until the open switch remakes, whichever is longer; open longer than 3 minutes, the code changes to lockout 13; remade sooner, 33 keeps flashing until the blower shuts off. The rollout switch requires manual reset. |
