Hello, I have a problem with a mouse or mice having taken refuge in the stove. How do I remove the stove top to clean it out? and also I think there might be a dead mouse in the bootom part above the drawer where the gas vents are. It smells so I just only use the cook top. I could only find 4 screws up front but it did not seem to release the top of the cook stove for me to get in there and clean it. I would really appreciate any help. Thanks
