Can you confirm that you have continuity between the following three points.
Unplug first ---
From the neutral side of the on/off switch and the common heater connection.
from terminal 3 on KN2 connector on the main pcb and one of the heater tags (not the common)
from terminal 3 on KN3 connector on the main pcb and the other heater tag.
Was the switch pushed in - ie on ?
Do you have a beeper on your multimeter ie when you put the two probe tips together there is a beep or buzz
OK you should have two pairs of wires connected to the switch, one live in ~ live out and the other neutral in ~ neutral out. With the switch in the on position you should get a beep between these two tags on each pair. If necessary remove the wires (noting where they go) and then check the switch.
OK you should then be able to connect between in inlet side of the switch and touch the common heater connection at the heater assembly and have a beep. Power off !!
OK if you follow the cable there is a thermal cutout in the line that should have continuity through it, If that has poped open circuit then this is your problem.
Yes that the one, the wiring diagram shows a cutout in that cable line to the heater, it may be actually near the heater.
Sometimes it is just a loose wire and replugging them reconnects. Glad you got it working. Could I ask you now to rate the information provided so that I can close the job down on the system. Many thanks. Ian
