Cool Cat A/C Not Cooling

[Jon in AZ]

2014 Chevy Roadtrek Popular 190. Worked fine last time I used it a month ago, but it's not getting cold now. Outside temperature is about 85 degrees and inside temperature is about 72 degrees. Thermostat is set to cool and I turned the setting all the way down to 60 degrees. Fan comes on and I thought I could near the compressor cycle on, but it doesn't seem to make as much noise as usual, and the air coming out is pretty much room temperature.

What should I be checking?

Well, our home AC just failed in exactly the same way on a very hot day last week. The problem was a failed start capacitor. This is a very common failure mode on hot days. Certainly one of the first things to check. You can often identify a failed (or about to fail) can capacitor by a small bulge on the ends. They should be perfectly flat.

Okay, that's helpful. Thanks!

I'll have to get the shroud off, and last time I tried the screws wouldn't budge. I'll have at it again. They're phillips head, so it's hard to get much torque on them without stripping.

Does an Easy Start bypass/replace the factory capacitor? If so, might be a good time to make the upgrade.

I was wondering about that. Thanks for the suggestion.

I'd private message this but I thought that the community might be interested. Is there a good place to donate for the covid for the reservation in AZ? If you have a link, please post. Might be off topic. I apologize. But it is important to me and perhaps others.

Sorry. If this is beyond the scope of the forum, please PM me, Jon.

The Cool Cat has to come off the roof to even check the start capacitor. For me it took two people and two ladders.

Anyone know the 2007 Roadtrek 210 Popular AC/Heat Pump Capacitor Part Number or Specs?

Jon,
The first thing to check on a Roadtrek AC is: Unplug the AC from the plug in near the unit, then run a 15 amp extension cord to a plug. Turn on to see if it powers up, that way you have eliminated all systems in the RT except for the AC unit.

Holy cow! Such an obvious and perfect first step! Should have considered that first. Thanks SO much for the common sense reminder, Rodie. Much appreciated.
