578594 Genuine Large Oven Fan Motor for Fisher & Paykel Ovens and Cookers

578594 is the large fan motor from Fisher & Paykel's cooking parts range, and this is the genuine part. In an oven, a motor like this spins the fan that moves heat around the cavity. There's also a small fan motor, 578596, plus a separate tangential cooling fan motor, so compare your old motor with both before deciding which one you need.

Oven fan noisy, slow or not spinning

Fan forced cooking relies on the fan to push hot air evenly over the food. When the motor's bearings wear, the fan starts to squeal, rumble or grind, and it may slow down or stop altogether. You'll notice food browning on one side, longer cooking times in fan modes, or a fan that stays still when a fan function is selected. A fan blade that's loose or rubbing on the back panel can sound similar, so check it's tight and straight first.

Changing the oven fan motor

Isolate the oven at the circuit breaker first. Many ovens are hard-wired, and those should be repaired by a licensed electrician. Access is usually through the back panel inside the oven or from the rear of the appliance. Photograph the wiring, note any earth lead, remove the fan blade carefully, then mount the new motor and refit the blade. Spin it by hand to check nothing rubs before restoring power.

Questions about this part

Large or small, how do I tell which motor I have?

Fisher & Paykel uses separate numbers for the two, 578594 for the large motor and 578596 for the small. The number is usually on the old motor's label or in your model's parts list. If neither is readable, send your model and serial number through the parts enquiry form.
