2001 fleetwood discovery air conditioner question

Got a problem with the air conditioners. Sometimes zone 1 cools and zone 2 doesn't it blows hot air. Next time zone 2 cools zone 1 doesn't it blows hot air. Changed the thermostat. Plugged into 50 amp plug. Amy suggestions? Anyone had this problem?

Thanks.
  • We have come up with an interesting situation here. We have an Intellitec ems system in the coach. There are times on 59 amp or gen service only one ac will operate. We shut it down pull all power including 12 volt from the Intellitec wait a few minutes, restore power system reboots both airs work fine until they shut off again. Then we have to go thru the same drill to get them running again. No other draw on the circuit.
  • Just a guess but perhaps how your coach may be parked, and where your temperature sensors are located, is the culprit. If one sensor is in the sun and the other in the shade, it can confuse them as to what the temperature is inside your coach.
