What to do if my Bryant Air Conditioner compressor and condenser fan will not start?
- N
  Nicole WebbAug 15, 2025
  If your Bryant Air Conditioner's compressor and condenser fan won't start, several factors could be at play. It could be due to a power failure, in which case you should contact your power company. Alternatively, check for blown fuses or tripped circuit breakers and replace or reset them as necessary. Other potential causes include a defective thermostat, contactor, transformer, or control relay, all of which would need replacement. Insufficient line voltage or incorrect wiring could also be the culprit, requiring you to determine the cause and correct it, or check the wiring diagram and rewire accordingly. Finally, ensure the thermostat setting isn't too high by lowering it below room temperature.

What to do if Bryant DURAPAC 580F Air Conditioner compressor will not start but condenser fan runs?
- A
  andrew03Aug 18, 2025
  If your Bryant Air Conditioner's compressor won't start but the condenser fan runs, the issue might stem from several causes. Begin by inspecting the wiring in the compressor circuit for faults or loose connections, repairing or replacing as needed. If the compressor motor is burned out, seized, or has an open internal overload, determine the cause and replace the compressor. A defective overload could also be the problem, so determine the cause and replace it. Check if the compressor is locked out, and if so, determine the cause for the safety trip and reset the lockout. Lastly, verify that all three phases of power are present; if one leg is dead, replace the fuse or reset the circuit breaker and determine the underlying cause.

Why does my Bryant DURAPAC 580F Air Conditioner have excessive head pressure?
- J
  Jose TerryAug 26, 2025
  If your Bryant Air Conditioner is showing signs of excessive head pressure, start by replacing the dirty air filter. If the condenser coil is dirty, clean it. If the refrigerant is overcharged, recover the excess refrigerant. Inspect the TXV, ensuring the bulb is tightly mounted to the suction line; if the TXV is stuck open or closed, replace it. If there is air in the system, recover the refrigerant, evacuate the system, and recharge it. Finally, check for any restrictions in the condenser air or air short-cycling, and correct as needed.

What to do if my Bryant DURAPAC 580F Air Conditioner has low system capacity?
- M
  Michael CherryAug 31, 2025
  If you're experiencing low system capacity with your Bryant Air Conditioner, it could be due to a low refrigerant charge or a frosted coil. Start by checking the charge amount, referring to the system charging section. If the evaporator coil is frosted, inspect and replace the subcooler control low-pressure switch if necessary.

What to do if Bryant Air Conditioner subcooler will not deenergize?
- A
  Angela SmithSep 3, 2025
  If the subcooler in your Bryant Air Conditioner will not deenergize, it is possible that the liquid line three-way valve will not close. If the valve is stuck open, replace it.

What causes poor flame characteristics in my Bryant Air Conditioner?
- B
  Benjamin WilliamsSep 7, 2025
  If your Bryant Air Conditioner has poor flame characteristics, characterized by aldehyde odors, CO, a sooting flame, or a floating flame, it may be due to incomplete combustion (lack of combustion air). Check all screws around the flue outlets and burner compartment and tighten them as necessary. Also clean vent for restriction as necessary.

How to troubleshoot a Bryant DURAPAC 580F Air Conditioner when the subcooler will not energize?
- R
  Ronald BradySep 12, 2025
  If the subcooler in your Bryant Air Conditioner will not energize, first check the power source to the subcooler control transformer and ensure all wire connections are tight, as the cause may be no power to the transformer. If there's no power from the transformer to the liquid line three-way valve, check the fuse and ensure wiring continuity. If the subcooler control low-pressure switch is open, cycle the unit off to allow it to reset; replace the switch if it doesn't close. Also, test the transformer to ensure it is working. If the liquid line three-way valve isn't operating, the solenoid coil may be defective (replace it) or the solenoid valve may be stuck closed (replace it).

Why is my Bryant DURAPAC 580F providing inadequate heating?
- T
  Tanya AndersonNov 20, 2025
  If your Bryant Air Conditioner shows signs of inadequate heating, start by checking the air filter and cleaning or replacing it if dirty. Ensure the gas input to the unit is adequate by checking the gas pressure at the manifold and clocking the gas meter for input; if too low, increase manifold pressure or replace with correct orifices. Other potential causes include an undersized unit (replace with a proper unit or add an additional unit), restricted airflow (clean or replace the filter, or remove any restrictions), or a blower speed that's too low (install an alternate motor or adjust the pulley to increase fan speed). Also, check the rotation of the blower, thermostat heat anticipator settings, and temperature rise of the unit, adjusting as needed if the limit switch cycles the main bur...

How to fix Bryant DURAPAC 580F burners that will not ignite?
- C
  Charles SotoNov 27, 2025
  If the burners in your Bryant Air Conditioner will not ignite, there are several potential causes. Start by checking the flame ignition and sensor electrode positioning, adjusting as needed if the spark electrodes are misaligned. If there is no gas at the main burners, check the gas line for air and purge it as necessary, allowing gas to dissipate for at least 5 minutes before attempting to relight the unit. If there is water in the gas line, drain the water and install a drip leg to trap any future water accumulation. Ensure the furnace has power by checking the power supply, fuses, wiring, and circuit breaker. Verify that there is 24v power supply to control circuit, checking the transformer (allowing a cool-down period for transformers with internal overcurrent protection before resetti...
