847020 Genuine Fridge Defrost Heater with Fuse 95W for Fisher & Paykel Fridges E388LXFD E388LMFD E388RMFD E388L E388R E308L E308R E388LW1

If the freezer section of your Fisher & Paykel E308 or E388 fridge keeps icing over, this genuine defrost heater is a likely fix. Part 847020 is a 95W heater supplied with a fuse, and it replaces the older numbers 818755 and 820671. It's listed for the E308L and E308R, plus the E388 range including the E388LXFD, E388LMFD and E388RMFD.

Frost on the freezer coil and a warm fridge

A frost-free fridge runs a regular defrost cycle to clear ice off the evaporator coil. This heater sits against the coil and switches on for short periods so the ice melts and drains away. If the heater or its fuse fails, frost keeps building until it blocks the air flow. You'll notice the freezer still feels cold but the fridge section warms up, a thick layer of ice forms on the back panel, or water leaks out once the ice eventually melts. A resistance check is a quick test, as this heater should read close to 116 ohms.

Replacing the defrost heater

Unplug the fridge and empty the freezer before you start. Let heavy ice melt naturally, as chipping at it can puncture the evaporator. The heater is behind the rear panel inside the freezer. Note how it's clipped to the coil and where the fuse sits, and photograph the connections. Check the defrost drain is clear while you're in there, then refit the panel and give the fridge a few hours to come down to temperature.

Questions about this part

Why does the heater come with a fuse?

The fuse protects the defrost circuit. Because it's supplied with the heater, you replace both at the same time instead of fitting a new heater next to an old fuse, which is good practice after a defrost fault.
