1. Remove oven shelves and base plate. Disconnect igniter lead from electrode.
2. Undo M3 x 6 Torx head screw securing electrode to bracket.
3. Remove electrode and replace in reverse order.
3.5 OVEN THERMOSTAT
Thermostat calibration: The thermostat does not require calibration. If centre oven
temperature is outside specified tolerances then replace thermostat and return faulty
thermostat to the Customer Care Centre.
1. Remove control knobs and facia panel as detailed in Section 3.1.1.
2. Remove hotplate as detailed in Section 3.1.2.
3. Undo thermocouple connection at FFD section of thermostat. Disconnect the oven
burner supply pipe at thermostat rear.
4. From inside the oven, note the route/location of the thermostat capillary/phial.
5. Gently pull the thermostat phial free from the left clip. Slide the phial to the left to free
the phial's clenched end from the right clip's locator hole.
6. Carefully feed capillary and phial through the oven top panel's hole.
7. Undo fixings which secure thermostat to gas rail.
8. Replace all parts in reverse order, renewing o-ring seal if necessary. Take care not to
overtighten thermocouple connection at thermostat rear.
3.6 GAS TAPS
Note: Plugs and bodies are machined in pairs and are therefore not interchangeable.
Always clean one tap at a time.
1. Remove control knobs and facia panel as detailed in Section 3.1.1.
2. Remove hotplate as detailed in Section 3.1.2.
3. Undo thermocouple connection at FFD section of gas tap. Undo burner supply pipe at
