AC not cooling

Hey everyone. We're having troubles with our 2020 TT's AC unit. We've had it for just over a year now, and up until this point everything had been running well. We primarily camp during the summer months, which means we're using the AC regularly.

Upon returning home and plugging in to our home's 30amp outlet, we found that the AC was no longer blowing cold air. Everything functioned as it normally would - unit clicks on and runs, blows just fine. But the air isn't cold.

I climbed up on the roof to see if there was anything obvious - like a wire coming loose during travel. I also verified that the compressor was clicking on and running when the unit started up.

The only thing I noticed was that the area under the capacitors was covered in a white, flaky substance. I've attached a pic for reference. Does this scream to anyone one of leaking caps? They don't appear to be bulging. Or would a leaking coolant line dry like this? The white substance appears to be isolated to the capacitor's compartment.

For the record, the unit is a Coleman Mach 15 (15,000 BTUs)

Any feedback would be greatly appreciated. Thanks!

Leave it off overnight then try it again next day. Might have froze up.

This is a link on how to check the capacitors although if the compressor runs they are probably ok.

If compressor running, check LARGE suction copper line to compressor; should be cool/ cold w/ compressor running. (Small line will be HOT gas) Check CLEANLINESS OF CONDENSER COIL? One fight w/ cottonwood tree blooms will clog one quick; if compressor running and coil clean, and air= warm and (UNIT NOT a HEAT PUMP??), possibly loss of refrigerant... reading the other day of recalls/ compressor seizures from copper tubing cracks/ freon loss on a batch of COLEMAN MACH UNITS? Any Other symptoms you have NOT mentioned? Did it cool for a while that day, then seem to start blowing warm? E.g. Small freon leak/ low freon can lead to poor cooling and compressor OVERHEAT where it cycles OFF/ON on thermal, before total failure from overheating?

Dometic Thermostat? If so check to be sure the thermostat control is on auto and not Lo or Hi.

There may be fuse inside thermostat. Check for it.
