41
Bryant communicating air conditioner (Evolution/Preferred series) shows code 41 on the indoor control or thermostat; outdoor fan does not run or runs erratically.
Outdoor Fan Motor Fault / RPM Feedback Error
44
Bryant communicating system displays code 44; outdoor unit does not respond to thermostat commands or shows intermittent communication loss.

51
Bryant communicating thermostat shows code 51; indicates outdoor unit capacity or staging error. System may run at wrong capacity or not stage up.
Outdoor Capacity / Staging Fault
53
Bryant system displays code 53; indicates outdoor temperature sensor fault. System may not operate correctly in low or high ambient conditions.
Outdoor Ambient Temperature Sensor Fault
55
Bryant communicating thermostat shows code 55; indicates discharge line temperature sensor fault. System may shut down on protection.
Discharge Line Temperature Sensor Fault
56
Bryant system logs code 56; indicates suction line temperature sensor fault. May affect superheat control and system protection.
Suction Line Temperature Sensor Fault
57
Bryant communicating system shows code 57; indicates compressor current or inverter fault on variable-speed models. Outdoor unit may not start or may shut down quickly.

67
Bryant system logs code 67; indicates low outdoor ambient lockout or low temperature operation fault. System may not run in very low outdoor temperatures.
Low Ambient Operation Lockout
Symptom
Bryant air conditioner causes lights to dim significantly when starting; occasional breaker trips on startup.
High Inrush Current / Electrical Supply Issue
Symptom
Bryant air conditioner cycles on and off normally but thermostat temperature reading seems inaccurate.
Thermostat Sensing Error
Symptom
Bryant air conditioner freezes up; ice forms on the indoor coil or suction line and cooling performance drops.
Evaporator Coil Icing
Symptom
Bryant air conditioner occasionally shuts off and thermostat goes blank, then comes back after a short time.
Low-Voltage Power Interruption
Symptom
Bryant air conditioner outdoor unit vibrates excessively during operation; unit may shake pad or make low-frequency rumble.
Mechanical Vibration / Mounting Issue
Symptom
Bryant air conditioner runs but humidity in the home remains high; air feels clammy.
Poor Dehumidification
Symptom
Bryant air conditioner runs but some rooms are too hot while others are comfortable.
Uneven Cooling / Air Distribution Problem
Symptom
Bryant air conditioner runs but there is a musty or moldy smell from the vents when cooling.
Biological Growth on Evaporator Coil or in Drain Pan
Symptom
Bryant air conditioner runs continuously but cannot reach the thermostat setpoint on hot days.
Underperforming Cooling / Capacity Loss
Symptom
Bryant air conditioner short cycles; outdoor unit starts and stops frequently (every few minutes) without reaching set temperature.
Short Cycling
Symptom
Bryant air conditioner trips the breaker immediately or shortly after starting.
Overcurrent / Short Circuit
Symptom
Bryant air conditioner will not start at all; thermostat calls for cooling but neither indoor blower nor outdoor unit run.
No-Start Condition (Control Power or Thermostat Circuit Failure)
Symptom
Bryant outdoor unit does not run, but indoor blower runs and blows warm air.
Outdoor Unit Power or Control Failure
Symptom
Bryant outdoor unit fan runs but compressor does not; no cooling is produced.
Compressor Not Starting
Symptom
Bryant outdoor unit hums but the fan and/or compressor do not start; may start if fan blade is spun by hand.
Failed Dual Run Capacitor
Symptom
Bryant outdoor unit is very loud during operation; rattling, buzzing, or grinding noises are heard.
Excessive Outdoor Noise
Symptom
Bryant outdoor unit runs but indoor air is not cold; supply air feels only slightly cooler than room temperature or not cool at all.
Insufficient Cooling Capacity
Symptom
Burning or electrical smell when Bryant air conditioner starts or runs.
Overheating Electrical Component
Symptom
Indoor Bryant system produces loud banging or booming noises when starting or stopping cooling.
Ductwork Expansion/Contraction Noise
Symptom
Outdoor Bryant condenser runs (fan spinning) but indoor blower does not run; coil may freeze and little or no air comes from vents.
Indoor Blower Motor Failure
Symptom
Water leaking from around the indoor Bryant air handler or furnace during cooling; water stains on ceiling below unit.
Condensate Drain Clog / Pan Overflow
