SAFETY CONSIDERATIONS
WARNING:
Improper installation, adjustment, alter-
ation, service, maintenance, or use can cause explo-
sion, fire, electric shock, or other occurrences which may
injure you or damage your property. Consult a quali-
fied installer or service agency for information or assis-
tance. The qualified installer or agency must use only
factory-authorized kits or accessories when repairing this
product.
Recognize safety information. This is the safety-alert sym-
bol. ( ) When you see this symbol on the unit and in
instructions or manuals, be alert to the potential for per-
sonal injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety-alert sym-
bol. Danger identifies the most serious hazards which will
result in severe personal injury or death. Warning indicates
a condition that could result in personal injury. Caution is
used to identify unsafe practices which would result in minor
personal injury or product and property damage.
WARNING:
Before performing service or mainte-
nance operations on unit, turn off main power switch
to unit. Electrical shock could cause personal injury.
1. The power supply (volts, hertz, and phase) must corre-
spond to that specified on unit rating plate.
2. The electrical supply provided by the utility must be suf-
ficient to handle load imposed by this unit.
3. Refer to the Locate the Unit section on page 2 and
Fig. 2 and 3 for locations of electrical inlets, required
clearances, and weight distribution based on recom-
mended support points before setting unit in place.
4. This installation must conform with local building codes.
Refer to local plumbing or wastewater codes and other
applicable local codes.
INSTALLATION
NOTE: When installing any accessory item, see the manu-
facturers installation instructions packaged with the acces-
sory. A qualified agency must use factory-authorized kits or
accessories when modifying this unit.
The 569C072,090, and 120 units use hermetic compressors.
The 576B090,102, and 120 units use semi-hermetic compres-
sors. Refer to Tables 1A and 1B.

Questions and Answers

    Why is my Bryant 569C compressor not running? Contactor open?
    • C
      Cathy OneillAug 14, 2025
      Several factors can cause the compressor not to run when the contactor is open. It could be due to a power outage, so restore power first. Check for blown fuses and replace them if necessary, after identifying and fixing the underlying cause. If the transformer is faulty, replace it if the primary windings receive power but there's no output. Also, verify the thermostat setting and inspect for an open thermostat circuit. Other potential causes include an open low-pressure or high-pressure switch, loose connections (tighten them), or an open compressor motor thermostat (check for excessive motor temperature).

    What to do if my Bryant 569C Air Conditioner compressor runs but cooling is insufficient and suction pressure is low?
    • A
      anna11Aug 18, 2025
      If your compressor is running, but cooling is insufficient with low suction pressure, consider these potential causes: a low refrigerant charge (add charge), low head pressure (check refrigerant charge), dirty indoor-air filters (clean or replace them), a defective expansion valve power head (replace it), a restricted or plugged expansion valve (remove and replace it), a partially iced evaporator coil (check the low-pressure setting), or restricted evaporator airflow (remove any obstructions).

    What to do if my Bryant 569C compressor does not run but the contactor is closed?
    • K
      kathrynchristianAug 21, 2025
      If the compressor doesn't run but the contactor is closed, first check the compressor leads for looseness or breaks with the power off. If single phasing is the issue, replace the blown fuse. Finally, if the compressor internal overload is open, allow the compressor motor windings to cool down to reset the overload and determine the cause for the overload opening.

    Why is my Bryant 569C Air Conditioner compressor running but cooling is insufficient and suction pressure is high?
    • T
      Tiffany ThomasAug 25, 2025
      If the compressor runs but cooling is insufficient with high suction pressure, the heat load may be excessive. Check for open doors or windows.

    What to do if my Bryant 569C compressor cycles on high-pressure switch and the condenser fan is on?
    • G
      Gail BrownAug 27, 2025
      If your compressor cycles on the high-pressure switch while the condenser fan is running, the high-pressure switch might be faulty and needs replacement. Another cause may be restricted airflow due to a dirty coil; remove any obstructions and clean the condenser coil. Air recirculation could also be the problem, so clear the airflow area. Also, refrigerant overcharge may cause this problem, so recover as required. Finally, check for any refrigerant system restrictions, such as a blocked filter drier or expansion valve, and replace them if necessary.

    Why is my Bryant 569C compressor cycling on the low-pressure switch with the evaporator fan running?
    • D
      Dylan CookAug 30, 2025
      If the compressor cycles on the low-pressure switch while the evaporator fan is running, several issues could be responsible. A plugged filter drier may be the cause, so replace it. A defective expansion valve power head could also be the problem, requiring replacement. Additionally, a low refrigerant charge might be the reason; in this case, find the leak, repair it, evacuate the system, and recharge. Finally, a restricted or plugged expansion valve may be the cause, so remove and replace it.

    What to do if my Bryant Air Conditioner compressor cycles on high-pressure switch and the condenser fan is off?
    • E
      Emily LaneSep 3, 2025
      If the compressor cycles on the high-pressure switch and the condenser fan is off, check the following: * Tighten fan hub screws if the fan slips on the shaft. * Check power and capacitor for 1/ and 3/ hp motor if the motor is not running. * Replace the motor if the motor bearings are seized or the motor is burned out with open windings. * Check overload rating and for fan blade obstruction if the motor overload is open.

    Why is there restricted airflow and low suction pressure in my Bryant 569C Air Conditioner?
    • T
      tgilbertSep 7, 2025
      Restricted airflow with low suction pressure can stem from a few issues. The evaporator coil might be iced up, so check the refrigerant charge. Alternatively, the evaporator coil could be dirty, so clean the coil fins. A dirty indoor-air filter is another possibility, so clean or replace the filters. Lastly, check the damper operation and position, as closed indoor-air dampers can also cause this problem.

    What to do if the indoor (evaporator) fan stopped with low suction pressure in my Bryant Air Conditioner?
    • A
      Anthony GreenSep 10, 2025
      If the indoor fan has stopped and the suction pressure is low, start by tightening all electrical connections. If that doesn't solve the issue, the fan relay may be defective and need replacement. Check the power supply if the motor overload is open. If the motor is defective, replace it. Lastly, inspect the fan belt; if it's broken or slipping, replace or tighten it.
