I feel like an an idiot even asking this I have a Beverage Air MT-49 commercial cooler unit, The horizontal bulb on the inside has burnt out, it is in a plastic sleeve and seems to be locked into the ends (ballasts?) I can’t for the life of me figure out how to unlock it, the flourescent bulb doesn’t spin or anything. And it doesn’t slide to either end. Any advice would be appreciated ---

It is supposed to turn like any other fluorescent bulb.
