Maytag Central air conditioner leaking at furnace or air handler
If your Maytag central air conditioner is leaking water at the furnace or air handler, the most likely cause is an evaporator coil that is not tilted toward the drain outlet. Condensation normally runs from the evaporator coil into the condensate drain pan, but an incorrectly positioned coil can send water over the pan edge and cause an air conditioner condensate leak. If the pan is not overflowing, inspect the drip tray first because a cracked Maytag drip tray can leak water even when it is draining normally. A cracked evaporator drain pan can cause the same symptom. If water is backing up or overflowing from the pan, a clogged condensate drain line or drain trap is the more likely cause. Turn off power to the air handler before clearing a clog or inspecting drain components. Enter your model number to find the exact replacement drain pan or other part for your specific Maytag central air conditioner. Drain and pan repairs are generally DIY tasks, but do not work inside energized equipment or on 240V wiring. Refrigerant or sealed-system repairs require an EPA 608-certified HVAC technician.
01 - Evaporator Coil Not Tilted Toward Drain
To help the condensate water to flow towards the drain outlet in the pan, most installers will tilt the evaportor coil slightly towards the drain hole. If the evaporator coil is not level, or tilted incorrectly, water will not flow to the drain hole and may overflow the pan.

02 - Maytag Central Air Conditioner Drip Tray
The evaporator is normally tilted slightly towards the drain hole to help the water to drain properly into the drip tray. If water is leaking from the drip tray but the tray is not overflowing, the drip tray is likely cracked and will need to be replaced.

The evaporator is normally tilted slightly towards the drain hole to help the water to drain properly into the drain pan. If water is leaking from the drain pan but the pan is not overflowing, the drain pan is likely cracked and will need to be replaced.
When the air conditioner is running, condensation forms on the evaporator coil and drips into a drain pan. From there the water is directed through a pipe with a trap to a floor drain or condensate pump. If the drain tube or trap gets clogged, the water will back up and overflow the drain pan. If water is leaking from the evaporator pan, it is likely the drain tube or trap is clogged and will need to be cleared to allow the water to flow normally. Be sure to shut off the power to the unit before attempting to remove the clog.
