[QUOTE="Geoff1946, post: 503412, member: 28452"] I'm very suspicious of your wiring modification when you removed the speed control. A common way of speed controlling a small motor is with three tappings on one winding. One tapping is connected to supply at a time, to give slow, medium, or fast. If you have connected any two tappings together that shorts out part of the winding, which WILL then get hot. I'm attaching a generic wiring diagram of a three speed fan. This is NOT your unit and wiring colours may be different but it may illustrate my point. [ATTACH]10982._xfImport[/ATTACH] [/QUOTE]
