As a former smoker, agree that vinegar and/or ammonia as a one-two approach can work out OK for cabinets. A little old fashiond shellac on the inside can be helpful, and of course, on the outside should you need to get going on the finish. The innerds usully stink of vermin, horrible capacitors, dust, and whatever fumes drifted up above the refrigerator where the suspect sat for decades or not. Otherwise , once the set heats up and is fixed, you or someone in the shop might identify the scent.
