Haier Central air conditioner is noisy or loud
Is your Haier central air conditioner making loud noise? Start with the simplest and most likely cause: debris hitting the condenser fan blade inside the outdoor condensing unit. Turn off power at the disconnect box and circuit breaker before inspecting or cleaning the unit. If the air conditioner is still making noise, the condenser fan motor may have worn bearings. With power off, carefully rotate the motor by hand; it should turn smoothly without grinding or wobbling. Loose grille or cabinet panels can also vibrate, creating an air conditioner loud noise or rattling sound, so tighten them as needed. Next, inspect the condenser fan blade for damage, looseness, or a loose set screw. A defective condenser fan motor or fan blade may need replacement. A noisy contactor is less common and can also prevent the condensing unit from operating correctly. Testing or replacing the contactor involves dangerous 240V line voltage, so hire a qualified HVAC technician unless you are trained and equipped for that work. Enter your Haier model number to find the exact replacement condenser fan motor, fan blade, panel, or contactor for your central air conditioner.
01 - Debris Hitting Fan
Over time debris can fall into the condensing unit, causing a noise when the fan is running. Inspect the fan blade and inside the unit for any debris. Clean out the outdoor unit as needed but be sure to shut off power to the unit before attempting to clean it out.

02 - Haier Central Air Conditioner Fan Motor
The fan motor has bearings that can wear out over time. When the bearings are worn out, they make loud noise. To check the bearings, try rotating the fan motor by hand. If the motor does not turn smoothly, replace it.

03 - Panels Vibrating
If the outdoor condensing unit is noisy, the grille or one of the panels may be loose and vibrating. Check for loose panels and tighten them as needed.
Highly Likely
04 - Haier Central Air Conditioner Fan Blade
The fan blade on the condenser fan motor might be defective or loose. To check the fan blade, wiggle the fan motor shaft. If the motor shaft is loose, tighten or replace the set screw. If the condenser fan motor is still making noise, replace the fan blade.

05 - Haier Central Air Conditioner Condenser Fan Motor
The condenser fan motor has bearings that can wear out over time. When the bearings are worn out, they make loud noise. To check the bearings, try rotating the condenser fan motor by hand. If the motor does not turn smoothly, replace it.
Less Common
06 - Haier Central Air Conditioner Contactor
The furnace control board sends a low voltage signal to the contactor. When the contactor receives the signal from the control board, it closes the circuit, sending voltage to the condensing unit components. If the contactor is defective, it will not provide voltage to the condensing unit. In addition, the contactor will make noise when it is defective. If the condensing unit is making noise but not cooling, the contactor has probably failed. To determine if the contactor is at fault, use a multimeter to test the contactor for continuity. If the contactor does not have continuity, replace it.
