There is NO fuse behind the burner. If you are talking about that black encased looking thing behind the burner that is the Flame burn fusable link. NOT a fuse. If you found that snap disc with the 2 red wires on the burner metal case, just jump those 2 wires. If the refer powers up that disc is either bad because it IS bad, or the refer overheated due to a ventilation problem or a BAD cooling unit. Doug
PS The Thermal snap disc have 2 models. 1 model has a resettable red button, the other does not. They both do the same thing
