Motor smells hot after two loads, like electrical burning. Armature core hot to touch, estimate 150 degrees. Suspect short in windings. Recently replaced coupling but that smells OK.

Is there a way to check this out before ordering a new motor?

Dear Senior Expert:

Thank You for the advice. Just a FYI. I checked the motor and pump for binding. No problem there. However I believed the new coupling was the source of the problem. The new coupling with the metal insert has a interferance fit and dosn't go far enough on the shaft, causing a side load on trans. and motor. I taped the coupling on the shaft(s) to the point that they were flush with end of each shaft. If you install by snapping motor latches there is about one eighth of an inch to flush on both coupling halves. Washed a coupla loads and no hot smell.

Thanks again,

Tom
