Heat is escaping from the main fan oven of my Cannon Henley double oven. The main oven door latch is fitted correctly as is the catch mounted inside the side panel of the cooker. The spring-loaded microswitch that turns the oven off when the door is opened functions correctly. There is not a correct seal being made around the rubber surround between the door and the oven and heat is escaping from the upper right portion of the rubber.
