So you mean that I have to pull the oven out from between the cupboards and I can then take off the side panels? Sorry to sound dense, but just double checking.
Yes that's what you have to do, you will have screws at both back and front, if you have a buddie sometimes you can just gently remove the rear screws and fold it back far enough to grasp the hinge plate whilst you change it over. More fiddly than difficult - Ian
Ok, I may not be able to do this until the weekend Ian, but I will report back then.
Really sorry, but not had a moment to pull the oven out and try to replace the hinge housing. Hoping to have a go at this tomorrow and then I'll report back.
