If your Jenn Air refrigerator coffee maker is leaking, start by checking the parts most likely to fail. A faulty control board or control board assembly is the top offender; a shorted board can keep voltage on the water inlet or dispenser valve and let water flow continuously, so look for burned components and verify the valve opens and closes. Next, inspect the tube or hose behind the dispenser for cracks or holes and replace any damaged tubing. Common causes after that include K-Cup pins that are clogged or not piercing the pod properly, which lets water spill, and a cracked coffee maker container or reservoir. Less often a damaged door assembly causes leaks by misaligning parts. Look for visible damage, run a manual valve test, and clean clogged pins with a paper clip before ordering parts.

Although it is not a common cause, a damaged door assembly could be causing the refrigerator coffee maker to leak. Inspect the door for any cracks or damage and replace if required.
If the refrigerator coffee maker is leaking, it's possible the coffee maker is dispensing too much water. This can be caused by a defective control board assembly continuing to allow voltage to be sent to the water dispensing valve, keeping the valve open. You can inspect the board assembly for signs of burning or a shorted-out component. You should first confirm there are no cracks or holes in the coffee maker container or hoses connected to the dispenser, as well as determine the dispensing valve is functioning normally before considering a control board assembly replacement.
If the K-Cup pod is not pushed down firmly, the lower pin may not pierce through the pod. If the pins are clogged or not piercing all the way through the K-Cup, water may leak from the coffee maker. If the upper or lower pins are clogged, they can be cleaned with a paper clip.
