Maytag Central air conditioner is noisy or loud
When a Maytag central air conditioner is making loud noise, start with the simplest cause: debris hitting the condenser fan blade inside the outdoor condensing unit. Shut off power at the disconnect box and inspect the fan and cabinet before cleaning. If your central AC making loud noise continues, the air conditioner fan motor may have worn bearings. With power off, rotate the motor by hand; it should turn smoothly without grinding or resistance. Loose grille or cabinet panels can also vibrate and cause air conditioner making noise. Next, check whether the condenser fan blade is loose, damaged, or wobbling on the motor shaft. A noisy condenser fan may need a replacement blade or condenser fan motor. A defective contactor can also make buzzing or chattering sounds and may prevent power from reaching the outdoor unit. Testing or replacing a contactor involves hazardous 240V line voltage, so have a qualified HVAC technician handle that work. Enter your Maytag model number to find the exact fan motor, condenser fan blade, panel, or contactor for your central air conditioner. Shut off power before inspection, and do not attempt refrigerant or sealed-system repairs without EPA 608 certification.
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 - Maytag 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.

Highly Likely
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 - Maytag 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 - Maytag 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 - Maytag 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.
