If this is the auto set version, is it under warranty? Less than 3 years old? If so take it to a shop and fix should be free. Otherwise, the fan motor is also a transformer, which puts out 24 vac to run the board. So could be fan motor or the board itself.

Hi there,
If the knob spins all the way around (and especially of it didn't always do that), it's broken. This could mean that the nut that holds the rheostat in place has come loose, or it could be that the wiper inside the rheostat has broken off the shaft. To find the voltage measurements, correct schematics, etc, I'd need to know the serial number of your welder.
Regards,
Carl

Usually either the Power Supply to, or, the Motor drive circuitry. Or even the "Feed motor" itself.
SOURCE: miller 175 trigger will not feed wire very
First thing make sure the lead cable is as straight as possible. and make sure the wire has a unobstructed path. then you should check the trigger input/output switch and see if the switch is getting power to it continuously. I hope this help please rate this thank you

This usually happens when the main Power semiconductors fail. You need to check out the two main places, the Power Supply, make sure ALL voltages are correct, and the main Output semiconductors, check these to make sure they are Not open circuit or short circuit.
