I have a Rangemaster 110 Electric oven bought 1999 and the clock is blank. I can use the oven as the reset still works although I can't see anything on the clock. Do you think I need a new clock? Also the door on the fan oven had a gap at the top side furthest from the hinge. The door shuts but heat is being lost. What do you recommend to fix this. Thanks
