573667 Genuine Oven Thermal Limiter 160 Degree for Fisher & Paykel Ovens, Overheat Safety Cut-Out, Fisher and Paykel Oven Part

This is the genuine Fisher & Paykel 160 degree limiter, part number 573667. A limiter is a safety device that watches for overheating and breaks the circuit when the temperature it senses climbs past its set point. Fisher & Paykel uses limiters to protect the wiring, controls and surrounding cabinetry. No model list is held for 573667, so confirm the number on the old limiter, or in your oven's parts list, before ordering.

What happens when an oven limiter trips or fails

Ovens carry one or more thermal limiters, small safety switches that open the circuit if a spot inside the appliance runs hotter than designed. When one opens, the oven can stop heating, the fan or light may drop out, or the whole appliance can seem dead even though power is reaching it. Some limiters reset once they cool and others stay open for good. A limiter that keeps tripping usually points to a second fault, such as a seized cooling fan or a control holding an element on, so track that down before fitting the new one.

Fitting the limiter safely

Isolate the oven at the switchboard and wait until it's stone cold. The limiter is part of the oven's fixed wiring, so have a licensed electrician fit it. Note exactly how the old one is clipped or screwed down, because firm contact with its mounting surface affects when it trips. Check the cooling fan spins freely before the oven goes back into service.

Questions about this part

Why does my oven keep tripping the limiter?

A limiter only opens when it senses too much heat. Repeated trips usually mean the cooling fan has stopped, vents are blocked or a control is holding an element on. A new limiter alone won't cure those faults, so have the cause checked as well.
