575636 Genuine Oven Trip Limiter Kit, Overheat Cut-Out for Fisher & Paykel OR90SDB Cookers OR90SDBGFX1

If the oven on your OR90SDBGFX1 has gone cold while the rest of the cooker seems fine, the trip limiter is one of the parts to check. 575636 is the genuine Fisher & Paykel trip limiter kit for the OR90SDB range, and the OR90SDBGFX1 is the model on file. It is a safety device, so replace it like for like with this part number rather than a lookalike.

What the trip limiter does and signs it has tripped

A trip limiter is a thermal safety cut-out. It monitors a hot area of the oven and breaks the circuit if the temperature climbs higher than it should, for example when a cooling fan stops or a thermostat sticks on. Once it opens, the oven elements lose power even though the clock, lights or hotplates may still work. Some limiters reset and others must be replaced. A limiter that trips again and again is usually reacting to another fault, so find out why it overheated before relying on the new part.

Fitting and safety

This is a safety part on a hard-wired cooker, so it should be fitted by a licensed electrician. Isolate the power at the switchboard and, if your cooker also has gas burners, turn off the gas supply too. Photograph the wiring and the mounting position before removing the old limiter. Once the new kit is in, run the oven and confirm it heats normally and any cooling fan runs.

Questions about this part

My oven has no heat but the clock works. Could it be the limiter?

It can be. A tripped or failed limiter cuts the oven elements while other functions carry on. Elements, the thermostat and wiring can cause the same symptom, so have a technician test the limiter for continuity before replacing it.
