Скачать или смотреть ERROR CODE 33 - Bryant Furnace constantly restarts

This shows what error code 33 looks like. To see how I fixed it, watch my other video.

#33 LIMIT CIRCUIT FAULT - Indicates a limit, draft safeguard, flame rollout, or blocked vent switch (if used) is open. Blower will run for 4 minutes or until open switch remakes whichever is longer. If longer than 3 minutes, code changes to lockout #13. If open less than 3 minutes status code #33 continues to flash until blower shuts off. Flame Rollout switch and BVSS require manual reset. Check for:
Restricted Vent
Proper Vent Sizing
Loose blower wheel
Excessive wind
Dirty filter or restricted duct system
Defective blower motor or capacitor
Defective switch or connections
Inadequate combustion air supply (flame rollout switch open)
