General
For access to individual controls refer to section on Replacment Parts and for wiring continuity checks refer to schematic
wiring layouts.
To check out the electrical wiring at the burner you will first have to have access to the burner chamber. Use the following
procedure:-
1. Isolate the electrical power supply.
2. Open up the bottom burner access door. Remove door and put in a safe place.
3. Unscrew the 4 screws holding the inner panel in place and remove panel.
4. Unscrew the 3 screws holding the louvered plinth in place and remove plinth.
The external mains connections are made to a terminal block in the front right hand corner of the cooker under the oven.
Re-connect the electrical supply and check that there is 230V power supply available across the mains input connections
L & N on the terminal block. If not then check connecting leads, fuse and whether power is available at mains plug.
If power is available across L & N check for continuity across cooker overheat thermostat and flue safety device.
