Kelvinator Central air conditioner leaking at furnace or air handler
When your Kelvinator central air conditioner is leaking water at the furnace or air handler, the condensate drainage system is usually the cause. The most likely problem is an evaporator coil that is not tilted toward the drain outlet, allowing condensation to miss the drain pan and overflow. Next, inspect the condensate drain pan (also called a drip tray) for cracks. If the pan is leaking without overflowing, replace the damaged part. A clogged condensate drain tube or drain trap is another common cause of an air conditioner leaking water, creating an AC condensate leak or water under the furnace from AC operation. Turn off power to the system before clearing a clog, and check that the drain line flows freely to the floor drain or condensate pump. Enter your Kelvinator model number to find the exact replacement drain pan or other part for your central air conditioner. Clearing a drain is generally a reasonable DIY repair, but correcting coil installation or replacing parts that require refrigerant-line disconnection must be handled by an EPA 608-certified HVAC technician. Avoid working inside the sealed system or on 240-volt wiring unless properly qualified.
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.
Common
02 - Kelvinator 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.

03 - Kelvinator Central Air Conditioner Drain Pan
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.
Common
04 - Clogged Drain Tube or Drain Trap
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.
