Set Appliance State:

Isolate Mains Power to appliance as per TOPs P4
Set Multimeter to Resistance Set meter to measure resistance
Remove the ignition electrode from the burner door
Disconnect the ignition lead from the PCB

Measurement:

Measure the resistance of the ignition electrode and lead.
Expected resistance approximately 1 kOhm.
Thoroughly inspect the ignition electrode and lead for;
  • Wear and/or warping.
  • Contamination.
  • Cracks and/or damage to ceramic.
  • Confirm electrode spark gap is 3mm +/- 0.5mm.
    Note.
    1. If required clean the electrode with a small brush (not with a wire brush) or emery paper.
    2. Always examine any seals or gaskets, replacing where necessary.
