The main AC unit has been fine and out of the blue, the AC unit stopped working regardless of what setting I use. I ran the thermostat up to 90 and switched over to the heat pump, nothing there either. Checked and cycled all the breakers on the interior panel and at the service box. Below is an image of the thermostat that came with the rig. The unit is a Coleman-Mach Model #48004-869

Not liking my Redwood right now. Any help is appreciated...

After completing the following, I was able to determine there is no 120v power at the AC unit. But thought it would help others to see the process I followed troubleshooting this problem. To follow are the step I took in to establish a loss of power to the unit:

1. Checked power at pedestal-both legs good
2. Checked power at the breaker- 120v
3. Checked all 12v fuses in the breaker box. All good.
4. Checked fuse and power to Thermostat. Good.
5. Bypassed the thermostat-jumped 12v power directly. AC Unit did not respond.
6. Check both capacitors with a multimeter. Both are good
7. Turned shore power on and check the 120v power to the AC before it drops into the capacitors-No power.

The AC unit is mounted right next to my Maxair fan, directly over the island in the kitchen and I am wondering if the trim above the island light (see image) is hiding access to the AC unit 120v power. My thought would be the connections to the AC unit are in a junction box that's hidden under the ceiling trim. I really don't want to pull the AC unit unless it's my own only option.

I appreciate any ideas or suggestions you may have...

Safe travels...
