I have a Coleman 9330e715 in my popup. I used an adapter to plug into my garage and ran the AC for about 10 seconds then it tripped the breaker in the garage. I have since wired in a 30 amp 120v box and plugged the campers electrical cord into it. I checked the voltage at the box and I have a surge protector, both checked out ok. I can plug things into the outlets and they work. The AC won't turn on, nothing, no fan, no ac... I checked the circuit breakers, none were tripped but I turned them off and on just in case. I checked all my fuses in the panel and all are good. Any idea where to go next? This unit has the controls on the unit itself, no remote thermostat. Thank you

Not too sure about your Coleman, but the first thing to check is to see if the t-stat (wall mounted??) uses a battery…Beyond that, I’d want to pull the cover off to access the power terminals for further eval…3 tons

Remove the ceiling cover, verify that you have 120 volts entering the unit. Check the connector to ensure that they connected securely.Turning breaker off without applying light pressure toward off doesn't always reset breakers.An improperly wired RV may have run AC unit through a GFCI receptacle. Verify that the GFCI receptacle is not tripped.

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.

Thanks for the replies. I pulled the control panel down from the ceiling and I do not have 120 volts to the control panel. Is there anything inline between the breaker and the AC unit?
