Tappan Central air conditioner is noisy or loud
When a Tappan central air conditioner is making a loud noise, start with the simplest cause: debris hitting the outdoor condenser fan. Shut off power at the disconnect box and inspect the condensing unit for leaves, sticks, or other debris before cleaning it out. If your air conditioner is making noise even after cleaning, the fan motor bearings may be worn. With power off, turn the condenser fan by hand; a motor that feels rough or does not spin smoothly may need replacement. Loose grille or cabinet panels can also vibrate and create an air conditioner loud noise, so check and tighten them. Next, inspect the condenser fan blade for looseness, damage, or a loose set screw. A noisy condenser fan or persistent AC fan motor noise can indicate worn bearings in the condenser fan motor. A buzzing noise from the contactor, especially when the unit is not cooling, may indicate a failed contactor. Avoid testing or replacing the contactor yourself unless qualified, since the condensing unit uses 240V line voltage. Enter your Tappan model number to find the exact replacement 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.

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 - Tappan 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 - Tappan Central Air Conditioner Condenser Fan Motor

Less Common
06 - Tappan 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.
