RC Comfort issue
Have a 2015 Adventurer with 2 HVAC units. Already had to replace the rear unit. Now, the thermostat shows both zones, and will show AC(cool) or heat, for each zone like it should but the front unit will not do anything, no fan, no compressor, in heat mode the front unit immediately turns on the gas heat, and the rear brand new unit only runs the fan. No compressor. Have read the "lockout" issues on other forums but it is not locked out, does not show "00" or anything like it. It also does not have an internal fuse to pull, though I have disconnected it, let it sit, turned power off to the coach, disconnected the batteries and reconnected, all with no impact. Having trouble believing that 3 total units could go bad inside of 24 months but.....any suggestions on next steps? Using the amp gauge the rear unit pulls 3( used to pull 16 or 17 when the compressor is on) and the front pulls nothing. Which makes sense. I am going to check the terminals up top but thought I would see if anyone had a similar issue or suggestion.
Thanks for taking the time to read...
