Shouldnt , but it does unfortunately !!! ,
ive seen it time to time over the past 20 or so years in the trade , motors are made out of a very thin winding wire, in a nutshell, usually only rated for appx 5 amps or less , protected with a very thin layer of a non Conductive Insulation Coating , when this wire gets heated up ,it eventually fails , and now you have a lower amperage winding short curcuit , , insulation is toast , the fuse is to large to protect this short , the fuse is based on the total amps this motor draws under normal working ampacity Unfortunately , windings are the weak spot in a motor, when she heats up it only takes 10 or so amps to cause a serious problem in the winding ,can be very unpredictable , i see it in factories we service , the conductors feeding the motors are fine , the motor just goes into self destruct mode , happens on alternators on vehicles as well , Scary stuff for sure , some serious toxic black smoke.......
Im not a Motor Engineer by any means , but thats the jist of the issue imo , what ive been taught...makes sense to me lol...
Unplug when Not In Use on a trip , or storing for periods of time ...
weve all been lucky so far....
