CODE: 32 
PROBLEM: Low Pressure Switch Open 
FIX: Low – pressure switch trip. Check refrigerant charge and indoor air flow. 

CODE: 45 
PROBLEM: Control Fault 
FIX: Outdoor unit control board has failed. Control board needs to be replaced. 

CODE: 46 
PROBLEM: Brown Out (230v) 
FIX: Line voltage < 187v for at least 4 seconds. 

CODE: 47 
PROBLEM: No 230v at Unit Measured at L1 and L2 on circuit board 
FIX: There is no 230v at the contactor when indoor unit is powered and cooling/heating demand exists. 

CODE: 53 
PROBLEM: Outdoor Air Temp Sensor Fault 
FIX: Outdoor air sensor not reading or out of range. 

CODE: 55 
PROBLEM: Outdoor Coil Sensor Fault 
FIX: Coil sensor not reading or out of range. Ohm out sensor and check wiring. 

CODE: 56 
PROBLEM: Thermistors out of range 
FIX: Improper relationship between coil sensor and outdoor air sensor. Ohm out sensor and check wiring. 

CODE: 71 
PROBLEM: Low Stage Thermal Cut out 
FIX: Compressor operation detected then disappears while low stage demand exists. Possible causes are internal compressor overload trip or start relay and capacitor held in circuit too long 

CODE: 72 
PROBLEM: High Stage Thermal Cut out 
FIX: Compressor operation detected then disappears while low stage demand exists. Possible causes are internal compressor overload trip or start relay and capacitor held in circuit too long 

CODE: 73 
PROBLEM: Contactor Shorted 
FIX: Compressor voltage sensed when no demand for compressor operation exists. Contactor may be stuck closed or there is a wiring error 

CODE: 74 
PROBLEM: No 230v at Compressor 
FIX: Compressor voltage not sensed when compressor should be starting. Contactor may be stuck open or there is a wiring error 

CODE: 75 
PROBLEM: Low Stage Did Not Start 
FIX: Specified start voltage at VR terminal was not achieved in low stage. Start relay was de-energized after 1 second 

CODE: 76 
PROBLEM: Low Stage Did Not Start 3 times 
FIX: For 3 consecutive low stage starts, the specified start voltage at VR terminal was not achieved and start relay was de-energized. Low stage locked out for 30 minutes. 

CODE: 77 
PROBLEM: High Stage Did Not Start 
FIX: Specified start voltage at VS terminal was not achieved in high stage. Start relay was de-energized after 1 second 

CODE: 78 
PROBLEM: High Stage Did Not Start 3 times 
FIX: For 3 consecutive high stage starts, the specified start voltage at VS terminal was not achieved and start relay was de-energized. High stage locked out for 30 minutes 

CODE: 81 
PROBLEM: Low Stage Thermal Lockout 
FIX: Thermal cutout occurs in three consecutive low/high stage cycles. Low stage locked out 4 hours or until 24v power recycled

Furnace Error Codes

CODE: Error codes 12 and 44  
PROBLEM: There's a fault with the blower calibration 

CODE: Error Code 13  
PROBLEM: Problem with the limit switch being tripped (furnace will auto reset after three hours) 

CODE: Error Code 14  
PROBLEM: Ignition problem (control will auto reset after three hours) 

CODE: Error Code 23  
PROBLEM: Problem with the blower airflow selection 

CODE: Error Code 34  
PROBLEM: The ignition process isn't working properly 

CODE: Error Code 41  
PROBLEM: The blower isn't operating at the right revolutions per minute 

CODE: Error Code 43  
PROBLEM: There's a fault with the pressure switch calibration 

CODE: Error Code 45  
PROBLEM: Lockout because of a problem with the control circuitry (furnace will auto reset after an hour)

Heat Pump Error Codes

Bryant heat pumps utilize a variety of error codes to indicate potential issues or malfunctions. If you encounter an error code, it's recommended to refer to the user manual or contact a qualified HVAC technician for assistance.

Here are some common troubleshooting steps you can take for heat pump issues:

Power cycle: Turn off the power to the heat pump and wait for a few minutes before turning it back on. Sometimes, a simple reset can resolve minor issues.

Check the thermostat: Make sure the thermostat is set to the desired temperature and operating mode (heating or cooling). Ensure that the batteries, if applicable, are not depleted.

Clean or replace air filters: Dirty or clogged air filters can restrict airflow and cause performance issues. Clean or replace the filters according to the manufacturer's instructions.

Inspect the outdoor unit: Check the outdoor unit for any visible signs of damage or obstructions, such as debris, ice buildup, or snow. Clear away any blockages carefully.

Check circuit breakers and fuses: Verify that the circuit breaker for the heat pump is not tripped and that the fuses are intact. Reset or replace them if necessary.

Verify the airflow: Ensure that all supply and return air vents are open and unobstructed. Blocked vents can affect the system's performance.

Check refrigerant levels: Low refrigerant levels can indicate a leak in the system. If you suspect a refrigerant issue, contact a professional HVAC technician for assistance.

Remember, these are general troubleshooting tips, and specific error codes may require different actions. For precise guidance and assistance with Bryant heat pump error codes, consult the user manual or reach out to an authorized Bryant service provider.
