  If your Miller Welding System has no weld output and the wire isn't feeding, but the fan motor continues to run, it could be due to a few reasons: * The thermostat TP1 might be open due to overheating. Allow the fan to run with the gun trigger switch off to cool the unit, which should close the thermostat. * Ensure the gun trigger plug is securely connected. * Try releasing the gun trigger and cycling the unit power off and back on again.
