My parents Canon CD2 gas cooker is throwing a wobbler and I think the
microprocessor/control unit is faulty.

Syptoms include LED display on front panel showing top or bottom oven on when
they're not.
Beeping at all times of day, not being able to set the clock or timer and the
LED temp display for the oven showing approx 3/4 way across even when not on !

Is the contoller easily changed and are spares available. Is there an online
diagram available any where.

Thanks in advance for any help
