Using this Fisher & Paykel fridge defrost water evaporation tray is easy. First, locate the compressor at the back of your fridge. The tray clips right onto it. As your fridge defrosts, the water will collect in the tray and gradually evaporate. When it comes to maintenance, it's a good idea to check the tray every few months. If there's a lot of debris or buildup, you can remove the tray and clean it with a mild soap and water solution. Just make sure it's completely dry before putting it back on the compressor. And remember, if you're not sure if this tray is right for your fridge, always check with us using your fridge's model number and product code before you buy.
