Waross - My first thought was cap. I bought a replacement that tests at 12.5 uF, the two originals come in at 12 uF. The new one sounds identical to the old ones. It is possible it is not the right sort as you suggest but I doubt it would fail the first second it was switched on and still test...
Lionel - I probably will flip it back at some point to get it back to spec, but sadly I am confident that isn't the issue, It did run quietly after I flipped the rotor but before I flipped the switch and shorted it, also I have an untouched one that now makes the same noise after being left...
Thanks for the reply!
Hopefully not too huge. These are all I have at the moment. Can get some of the whole machine later on, can I attach a video of it running?
Last one of switch shows a sheared stud, this I guess happened on Assembly at the factory but hadn't caused any issues until I...
I find this rather odd - nobody has practically measured the actual output of a heater in these scenarios, you are still measuring voltage, and then inferring what that means practically. As the differences you are debating are huge- surely you could just rig up a heater and see if it gets hot...
The more I read up on this the less ideas I have-
1. It seems like if you have the wrong ( or damaged) capacitor then you can get noisy running as the windings aren't properly energised 90 deg out of phase. Yet every one I have tried is within spec.
2 If I disconnect one lead of the capacitor...
"Spinning the switch"? Did you mean a centrifugal switch? If so, it is NOT a PSC motor, it is a Capacitor Start motor. Different animals. If it is a Capacitor Start / Induction Run (only one capacitor), then my guess is that in running it jammed, the centrifugal switch welded shut, meaning the...
I should mention that am in the UK so 240v.
We run small linishers for light production and also teaching- these have been 100% reliable until the last month. We unpacked and set up a brand new one and the belt jammed, a student left it on but stalled for a few minutes. We let it cool down and...
