I know the AC circuit breaker is correct because with the AC running if I throw the switch the AC turns off.

Edited to add: My AC unit is an Airxcel. This is what I know about my current t-stat.

R Red + 12 VDC
B Blue -12 VDC
Y Yellow Compressor
GH Green High Fan
GL Gray Low Fan
W White +12 VDC Furnace

I'm guessing that the Red wire turns on the AC. The Blue, I'm not sure. Is it the ground or does it shut off the AC? The others I think I know.

Edited to add even more: When I test VDC I get 12 volts on each wire. When I disconnect the AC power from the outlet I still get 24 VAC. This makes no sense to me. Maybe I'm just not smart enough for this stuff.
All of your voltage readings are correct. But why you still have voltage with everything turn off and the TT unplugged does not sound right at all. That may be another issue all together.
Back to the T-stat. This is a spring switch thermostat that you are dealing with. Right? Can you post a pic of it with the cover off?

Short answer, nope not a spring switch. Its an electronic t-stat.
Really out of my realm of knowledge.
Sorry. I did a quick Google search of your model and it gave me the voltage readings that should be present at the T-stat. All of which matched what you reported. I do know that the electronic ones can go bad. They have a temp sensor eye the goes bad. So that may be your issue but the the electronic ones are a little harder to diagnose.

Ok guys. I have a 2306 that had the same thermostat problem you are talking about.

The problem is the wall it's mounted on shares the same wall as the refrigerator. That cavity gets really hot with the refrigerator running and heats that cavity up really hot. There is no air flow behind the thermostat in that cavity so the thermostat always thinks it's really hot in the camper. That's why the air conditioner runs till icicles form inside.

I installed two small computer fans in the edge of the cavity to circulate the internal camper air in and out if the cavity. I wired them in series so each 12 volt fan runs on 6 volts. They can't even be heard running. Fix was cheaper than relocating or purchasing a new thermostat.

The problem is not that it's an analog or digital thermostat, it's that the wall it's mounted on is blistering hot.

I will supply photos if my modification if you are interested.

I too have a 2306 and don't think I have that problem but I sealed up the wire hole when I put in my new digital thermostat. But always interested to see a mod, post the photos if not too much of a hassle. Thanks.

When I go out later today I will take some photos. I discovered this actually by accident while adding the "sub woofer" to the stereo. Another worthy modification I posted. With the stereo out and refrigerator running continuously in the driveway, that cavity and wall was blistering hot. I can honestly say the fans did fix the air conditioner which wouldn't shut off problem.

I have never felt any of that heat but maybe mine is a little different or because I didn't add the subwoofer. I am installing a whole new audio speaker system. Will post that mod when I get it done.

BTW, I am just about to open (remove) the speakers in the ceiling of my 2306. Do they just snap off (the grills) and then remove the screws to take off the base of the unit?

Never replaced the interior ceiling speakers. The Genesis unit that came with the camper is not too bad. Just the bass region of the audio source is noticeably missing. The documentation (wiring diagram) that came with the bag of brochures showed a connection for a sub woofer. This is really a misleading thing. It is a "bass speaker" connection, not a sub woofer. I added a small JBL cube speaker to the clipped off wiring. The difference is amazing. It's mounted on the wheel well under the dinette table. Just try that before you change the ceiling speakers.

I know the thread is old but Im a new 2306 owner and having the same problem with thermostat not accurate because of heat from fridge. Has anyone came up with other solutions for this problem? I can't even get the genesis out because of where the wires plugged into. Would insulating this whole wall help? Any input would be helpfull before I tear the wall out. Thanks
