Here is a video of me cleaning a refrigerator defrost drain. Pay special attention to the actual layout and construction of your unit. Every fridge is different but the basic principal is the same.
Step by Step
- Clear out the fridge and freezer space so you can work and so that you don't damage food.
- Turn off or unplug the fridge and allow it to set with the doors open for an hour or two to defrost and warm up.
- Remove the back panel in your freezer and expose the cooling coils and drain pan.
- Use both warm water to melt ice and a pipe cleaner or compressed air to flush out the drain line.
- Access the lower drain catch pan by either removing the lower back panel behind the fridge or by removing the air grate in the front.
- Make sure the drain line is unobstructed and clean out the pan under the fridge.
- It's a good idea to clean the dust and lint off of the lower coils, compressor and fan at this point. Compressed air works well.
- Test the drain with more warm water. If it works, put everything back together.
