New Dometic 15000 replacing 15000 now both ACs wont work
 
Replaced a dometic 15000 with a new Dometic 15000. Now the thermostat shuts off and neither AC is working. Any ideas? 2007 Monaco Diplomat.

Did you use the conversion control board so the new A/C is compatible with the older 5 button thermostat?
Or did you use the new CC2 programmable thermostat?
The new CC2 thermostat is not compatible with the older A/C units.
Or, the control board dip switches are nor correctly set.

Thank you. The Tech did not use the conversion board. I gave him your previous writeup. Same unit. Were back to the shop monday. Thank you. Very helpful. We should be good now.
