575720 Genuine Spark Ignition Electrode 810mm for Fisher & Paykel Gas Cooktops, SR Semi-Rapid Burner

Genuine Fisher & Paykel electrode 575720 is the spark ignition electrode for the SR, or semi-rapid, burner on F&P gas cooktops, with an 810mm lead. It is the small ceramic-insulated pin beside the burner that clicks and sparks to light the gas. Lead length and burner size both matter with electrodes, and F&P lists other versions such as 575722, so match the number on your old electrode first.

No click or no flame? Spark electrode faults

When you push and turn the knob, the ignition module sends a high voltage pulse down the lead, and a spark jumps from the electrode tip to the burner to light the gas. If one burner won't click while the others do, or it clicks but won't light, the electrode is a prime suspect. Cracked ceramic, a tip bent too far from the burner, a lead that has chafed through and shorts to the chassis, or spill residue on the tip all weaken or misdirect the spark. Sparks visible underneath the cooktop are another giveaway.

Fitting the electrode

Isolate power to the cooktop and turn off the gas before starting. Australian rules require gas appliance work to be done by a licensed gas fitter. Lift the cooktop or remove the burner parts to reach the electrode, then follow the lead back to the ignition module and route the new lead the same way, away from hot surfaces and sharp edges. Check the spark at every burner before refitting trims.

Questions about this part

Does the lead length matter?

Yes. The lead has to reach from the burner position to the ignition module without being stretched or bunched up near hot parts. This electrode has an 810mm lead for the SR burner position, so a version with a different length may not route correctly in your cooktop.
