cooker ignition

[tom morris]

I've got a Cannon Camberley gas cooker and cannot get the electrode to
spark in the grill . The bottom oven and ring burners are perfect,
spark every time. I have tried cleaning existing electrode with a nylon
brush and inspected for loose cables. It sparks intermittently, about
once every 30 clicks. I have noticed that the grill electrode works
fine when the top oven is started, weird!


I have changed the electrode with a new original part, and has not
cured the problem.How would I go about measuring the Ht lead for correct continuety or should I be measuring for resistence ? All I have is a mini voltmeter.

Sounds as though you've just about narrowed it down to a single area. If everything else is OK it must be the HT connection to the electrode.

You should be checking for an open circuit on the HT lead (V. High resistance). I can't be specific as I believe that HT leads have a fairly high resistance anyway. Either that or check that the insulation hasn't gone anywhere in the circuit and that the voltage is gong to earth somewhere before the electrode.
