High-Pressure Switch Open (Lockout)
32
Bryant outdoor unit runs briefly then shuts down; the diagnostic LED shows code 32, indicating the low-pressure switch is open. The indoor blower may continue to run with warm air from the vents.
Low-Pressure Switch Open (Loss of Charge or Restricted Flow)
33
Outdoor Bryant condenser attempts to start but shuts down quickly; the control board flashes code 33, indicating a discharge line temperature or compressor over-temperature fault.
Compressor Overheating / Discharge Temperature Fault
34
Bryant air conditioner outdoor unit does not start; the control board shows code 34, indicating a low-voltage control circuit fault or an open contactor coil circuit.
24V Control Circuit Open / Contactor Coil Fault
41
Bryant communicating air conditioner (Evolution/Preferred series) shows code 41 on the indoor control or thermostat; the outdoor fan does not run or runs erratically.
Outdoor Fan Motor Fault / RPM Feedback Error
44
Bryant communicating system displays code 44; the outdoor unit does not respond to thermostat commands or shows intermittent communication loss.
Outdoor Unit Communication Fault
45
Bryant Evolution/Preferred thermostat shows code 45; the outdoor unit is locked out and will not run until power is cycled.
Outdoor Unit Lockout (Multiple Faults Detected)
51
Bryant communicating thermostat shows code 51; this indicates an outdoor unit capacity or staging error. The system may run at the wrong capacity or not stage up.
Outdoor Capacity / Staging Fault
53
Bryant system displays code 53; this indicates an outdoor temperature sensor fault. The system may not operate correctly in low or high ambient conditions.
Outdoor Ambient Temperature Sensor Fault
55
Bryant communicating thermostat shows code 55; this indicates a discharge line temperature sensor fault. The system may shut down on protection.
Discharge Line Temperature Sensor Fault
56
Bryant system logs code 56; this indicates a suction line temperature sensor fault. This may affect superheat control and system protection.
Suction Line Temperature Sensor Fault
57
Bryant communicating system shows code 57; this indicates a compressor current or inverter fault on variable-speed models. The outdoor unit may not start or may shut down quickly.
Compressor Overcurrent / Inverter Fault
58
Bryant system logs code 58; this indicates high compressor temperature or an internal thermal protection trip on variable-speed models.
Compressor Thermal Protection Trip
59
Bryant communicating thermostat shows code 59; this indicates a low compressor speed or RPM feedback error on variable-speed models. The outdoor unit may not start or may shut down quickly.
Compressor Speed / RPM Fault
67
Bryant system logs code 67; this indicates a low outdoor ambient lockout or low temperature operation fault. The system may not run in very low outdoor temperatures.
Low Ambient Operation Lockout
Symptom
Bryant outdoor unit runs but indoor air is not cold; the supply air feels only slightly cooler than room temperature or not cool at all.
Insufficient Cooling Capacity
Symptom
Burning or electrical smell when the Bryant air conditioner starts or runs.
Overheating Electrical Component
Symptom
The Bryant air conditioner causes lights to dim significantly when starting; occasional breaker trips occur on startup.
High Inrush Current / Electrical Supply Issue
Symptom
The Bryant air conditioner cycles on and off normally, but the thermostat temperature reading seems inaccurate.
Thermostat Sensing Error
Symptom
The Bryant air conditioner freezes up; ice forms on the indoor coil or suction line, and cooling performance drops.
Evaporator Coil Icing
Symptom
The Bryant air conditioner occasionally shuts off and the thermostat goes blank, then comes back after a short time.
Low-Voltage Power Interruption
Symptom
The Bryant air conditioner outdoor unit vibrates excessively during operation; the unit may shake its pad or make a low-frequency rumble.
Mechanical Vibration / Mounting Issue
Symptom
The Bryant air conditioner runs continuously but cannot reach the thermostat setpoint on hot days.
Underperforming Cooling / Capacity Loss
Symptom
The Bryant air conditioner runs, but humidity in the home remains high; the air feels clammy.
Poor Dehumidification
Symptom
The Bryant air conditioner runs, but some rooms are too hot while others are comfortable.
Uneven Cooling / Air Distribution Problem
Symptom
The 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
The Bryant air conditioner short cycles; the outdoor unit starts and stops frequently (every few minutes) without reaching the set temperature.
Short Cycling
Symptom
The Bryant air conditioner trips the breaker immediately or shortly after starting.
Overcurrent / Short Circuit
Symptom
The Bryant air conditioner will not start at all; the thermostat calls for cooling, but neither the indoor blower nor the outdoor unit runs.
No-Start Condition (Control Power or Thermostat Circuit Failure)
Symptom
The Bryant outdoor unit does not run, but the indoor blower runs and blows warm air.
Outdoor Unit Power or Control Failure
Symptom
The Bryant outdoor unit fan runs, but the compressor does not; no cooling is produced.
Compressor Not Starting
Symptom
The Bryant outdoor unit hums, but the fan and/or compressor do not start; it may start if the fan blade is spun by hand.
Failed Dual Run Capacitor
Symptom
The Bryant outdoor unit is very loud during operation; rattling, buzzing, or grinding noises are heard.
Excessive Outdoor Noise
Symptom
The indoor Bryant system produces loud banging or booming noises when starting or stopping cooling.
Ductwork Expansion/Contraction Noise
Symptom
The outdoor Bryant condenser runs (fan spinning), but the indoor blower does not run; the coil may freeze, and little or no air comes from the vents.
Indoor Blower Motor Failure
Symptom
Water leaking from around the indoor Bryant air handler or furnace during cooling; water stains on the ceiling below the unit.
Condensate Drain Clog / Pan Overflow
