Coleman Mach ac not blowing

Hello everyone. First question for the forum. I have a 2022 Keystone passport 221BHWE with the Coleman Mach 15,000 bcu ac. I stayed in the trailer last night because my daughter had friends over and I needed to get away ��. I turned the ac on (working perfectly) and went to bed. I woke up in the morning (trailer was hot) and the ac was running but hardly any cold air was coming out of the vents. This is a ducted ac system but I had the dump vent open on the main unit. I turned off the ac and let it sit for an hour. Turned it back on and same thing, hardly any air coming out of ac. It’s cool air but hardly any. Any suggestions?

What is the power source that you're using to connect the trailer ?????

If you're using a extension cord and a 15 amp "garage outlet", the issue may be voltage drop and not enough amperage to start the compressor in a "high head pressure environment?

It should (but won't always) trip the circuit breaker on the garage circuit....

I’m using a 220 outlet and a 30 amp extension cord to the trailer.

If it's actually 220 volts unplug it ASAP!
And DO NOT plug it back in until that plug has been correctly wired for 30amp 110 volt.
Then ALWAYS use an EMS any/every time you plug into any shore power source.

I apologize it is a 30 amp outlet. I misspoke.

If you had the dump vents open and the temp set low then the air likely recirculating and froze the coil over. Air will not blow thru a block of ice. Leave it off and wait, it may take a couple of hours for it melt.

Thank you I was hoping. I will wait some time and see if that helps. I did pull the filter covers off earlier and noticed some frost so hopefully I don’t have any major issues.
