574501 Genuine 5 Position Oven Function Selector Switch for Fisher & Paykel, De'Longhi Ovens OB60HCEX1 OB60HDEX2 OB60HDEX4 OB60S3LCX2

Genuine part 574501 is the five position function selector switch from Fisher & Paykel OB60H ovens, the switch behind the knob you turn to choose the cooking mode. Its earlier number is 050032, which also shows up in De'Longhi listings. Models on file include the OB60HCEX1 and OB60HCEX2, the OB60HDEX1, OB60HDEX2, OB60HDEX3 and OB60HDEX4, and the OB60S3LCX1 and OB60S3LCX2.

Oven function knob not selecting modes?

The function selector routes power to the right combination of elements, fan and oven light for each cooking mode. Inside are spring contacts that make and break as the knob turns. Heat, food spills and arcing wear those contacts, and the switch starts to misbehave. You might find that one or two modes do nothing while others work, the light comes on but the oven never heats, the knob feels loose or skips positions, or there is a scorched smell and discoloured terminals behind the panel. Test the elements first, as a burnt out element gives similar symptoms.

Replacing the selector switch

Ovens are normally hard-wired, so have a licensed electrician do this job, with the oven isolated at the switchboard first. Before disconnecting anything, photograph or label every wire on the old switch, because each terminal feeds a different element or the fan. Fit the new switch, refit the knob and test every function position in turn.

Questions about this part

My old switch says 050032. Is this the right one?

Yes. 050032 is the earlier number for this switch. If that number or 574501 is printed on your old selector, this is the matching replacement for your oven.
