We have a 2007 45CC with a Tappan TC1450SB oven. The microwave function of the oven seems to have failed, in that trying to operate it shuts off the circuit switch on the shore power panel. There is a cover panel holding the oven in place, with a catch/latch of some sort which you can see on each side of the cover panel. Has anyone managed to work out how to remove the cover panel? It looks like you need to push something into the catch/latch.
