why would my electrical cord on my rainbow vacuum cleaner become hot inuse ?
my rainbow SE (Brown one) electrical cord becomes hot when plugged into outlet and is being used. Do I need to replace the cord, and if so, how would I do it?
You do not say which end of the cord gets hot but I would guess the plug end...
The heat will be generated from a bad connection - probably in the plug - just a small amount of resistance in a bad connection where there's been a bit of sparking and blackening will cause heat to be generated.
Solution - cut off the plug and perhaps six inches of cord and fit a new plug.
If you leave it and allow it to continue to heat up then the insulation around the individual wires will eventually melt - they will touch together - fuses will blow and trips operate. The outer sheath may melt and cause a shock hazard.
Good Luck...
