3. Open oven doors, remove shelves and oven base panel.
4. Remove nut securing thermocouple sensor to burner bracket.
5. Remove thermocouple from bracket. Pull remainder of thermocouple into oven, through
hole in left hand oven side panel.
6. Replace in reverse order and take care not to overtighten the connection at the
thermostat rear.
3.4 OVEN IGNITERS AND ELECTRODES
Igniter is piezo spark type and contains no batteries. Unit comprises piezo, housing,
lead and electrode assembly. Lead is push-fit at piezo and electrode ends. Oven igniter
electrode tip should be positioned 3.5mm from burner port.
3.4.1 Oven igniter
1. Remove the facia panel as detailed in Section 3.1.1.
2.
Disconnect earth wire (if fitted) and electrode lead from piezo housing.
3. Remove nut holding igniter in place and remove igniter.
3.4.2 Oven electrode
Note:
Care should be taken not to damage the electrode.
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
gas tap rear.
4.
Undo fixings which secure tap to gas rail.
5. Replace all parts in reverse order, renewing o-ring seal if necessary. Take care not to
overtighten thermocouple connection at gas tap rear.
3.7 FAULT CHECK LIST
If a flame is not established on any burners (hotplate or oven), follow this check list:
1. Check mains gas is ON.
2.
Check pressure at pressure test point to ensure gas is flowing to the appliance.
3. If gas is present then check burner injector for blockage.
4. If injector is clear then check FFD magnet unit is engaging and allowing gas to pass.
5. OVEN ONLY - Check for spark at spark electrode.
6. OVEN ONLY - if there is no spark then check spark gap and igniter lead connections.
Also check igniter and earth lead connections (if fitted).
