Range style cooker (Parkwood Rainham ME8)

New World cooker, dual fuel, 1m wide - 1 fan oven (electric), 1 non-fan electric oven, electric grill and gas hob. It all works apart from the timer (the clock bit works and you can set the timer but it's gone very quiet so you can't really hear it). One knob has been broken by the fitters in removal but you can get spares. Need it collecting asap if interested as new kitchen is being delivered today!
