See what's happening and how to try the first recovery step.

Check the defrost drain in the freezerRemove all food from the freezer and look for ice buildup near the back wall. Use a turkey baster with hot water to flush the drain hole if it's frozen.

Inspect the water supply linePull the fridge out from the wall and examine the plastic water line connected to the back. Look for cracks, kinks, or loose fittings.

Clean the drip panLocate the shallow drip pan under the fridge (usually near the compressor). Remove it and empty any stagnant water, then scrub with soapy water.

Tighten the drain tube connectionFind the rubber or plastic drain tube that runs from the defrost drain to the drip pan. Ensure it is securely attached and not disconnected.
