So I have been working on a fridge build off and on all summer for a customer of mine who has been trying to use a little digital Bradley smoker in their restaurant. It isn't holding up well to the heavy use. The last 2 weeks I've been working hard on it. Here's what I've got so far. Will post more pics later. Not letting me for some reason today. It's an early 50's general electric. Heating element will be on the top of the fridge tub with a convection oven fan to circulate. electric element in a separate smoke box underneath with a 1.5" steel pipe to vent the smoke in. I was able to re-use the controls from a hot plate that the smoking element came out of to be able to dial it in and not over heat and burn up the wood too quickly. its mounted on the back of the smoke box out of sight. I have an Auberns 1800w dual controller that I will mount in a control box with a few other switches on the right side.
