Do I Smell Smoke?

Went in to service a walk-in freezer in an old cafe, that was badly iced/ frosted up I found it odd that the fans were connected by cord/ cap disconnect, as they would usually be hard0-wired AND THEY were connected with a 120V plug. This was unusual as most these units were 240

I got out my (then) VERY expensive Grainger heat gun and plugged into the evap fan connector. I DID HAVE SOME reservations, but was not quite that smart "yet."

Turned the damn thing on for about 2 seconds and instead of a nice dull red glow, I got a white-hot LIGHT out of the gun. Did not seem to hurt it though.

Even back in the 80's--early 90's these were 80 bucks or so
