No Heat. Have checked heating elements directly. 4 Cables (yellow/black/white and red). used a separate direct power supply and elements heat up (red/black and white/black) for the 2 heat settings. Thermal cut-out in series (black wire in and out) are both live when power is on.
Yellow cable is the dead one so this must be the control but don't know where this goes to.
Tried new Relay/PCB and still no heat.

the wriring harness (with a few yellow cables goes to the rotary switch/timer.

Can you advice or link me to a wiring diagram I can follow to see where the yellow heater cable goes to?
Thanks
