Hi Steve, ring up extracare on 08457959722 and they will put you through to the parts dept.This is a Stoves made cooker I think and they are not cheap but cheaper than a new oven.You may have to pull the oven out a bit and look on the top for the rating plate as select 610 is the style.The model will be ADP 3420 etc. Three letters and four numbers. All the best.
