Had this problem. Air conditioner will not run without the fan. At least on my Coleman Mach 10. It’s easy to replace the capacitors. Mine did not have a start capacitor like the older ones (2018) so I sent that back and replaced the fan capacitor. Then I replaced the run capacitor because the fan worked but not the air. That fixed it.
Check that the fan spins freely. Check that the barrel fan above the filter spins freely too. If it’s the fan motor it can still be fixed but that part is more expensive. Still less than a new unit.
