Coleman mach fan runs fine but A/c hums intermittently

The issue with the generator that gets low and high when it start running out of gas that effect the A/C and result of high voltage getting to the unit and burn the capacitors and it should by saved by the fuse make sure that the gen not run out of gas if you have the A/C on and that the fuse is the correct one for the A/C and again check the air and see you may got a bad capacitor.
