I think the inverter has/is going out on my 3520A lathe. I'm having problems with getting it started or keeping it running. Here are the symptoms:
Flip on the manual disconnect
Pull the red power switch on...nothing happens. The LED readout on the inverter shows "o" and "c".
I turn the disconnect off and wait a few minutes before flipping the disconnect on again.
After doing this a time or two, I can usually get the LED to show an "F" in the upper left corner and numbers are on the LED display (I assume this is the voltage reading)
I pull the on/off switch on and the lathe starts.
After a few minutes the speed starts slowing down and the LED reads "OFF". Doesn't matter if I adjust the speed or not, it will just stop running.
I can repeat the above steps and it will sometimes come on, but again for only a few minutes.
I called Powermatic and the service tek said it sounded like the inverter going out.
Before I spend $500+ I thought I'd ask and see if anyone else has had this problem and if so, how did you fix it.
