Thank you very much. Tested the components first - all OK. Then tested the wiring to each component as per your instructions. The live feed goes into the clock first, then to the thermostat. Found there was no live feed on the wire going from the clock to the stat so removed that and found...
Thank you both for your advice. Think it is wiring problem but hard for me to check without a wiring diagram - any idea where I might be able to get one?
The bottom oven of my mum's cooker is not heating. Everything else - hob, top oven and grill all OK. When you turn the knob to switch it on the red light comes on but the fan doesn't turn and it doesn't heat.
Wondering if it might be the clock - can anybody confirm what the display should show...
