  1. I wanted to let you all know that I got the front AC working, after retrying several of the things above, mainly-turning off all power including the breakers and doing a reset then trying with the generator the front unit is running-This is great!! I did go on the roof but there are 14 rusty screws-I'll let my husband take the shroud off when I get home :). So I"m happy with the one A/C unit. At least I know that it isn't the dometic thermostat and that it is likely a connection at the A/C unit. Again-thanks
  2. First, I want to thank all of you for your help/suggestions. I tried a total power off system (including house batteries) with breakers and fuses out for 20 min and that did not do anything-except the controller was not showing an error all the time on zone 1-however nothing responded regardless (putting in fan mode didn't respond). This am I tried the reset, and that did not work, in fact it is showing a zone 4 only and nothing else-so I am assuming it is a bad controller. Are these known for going bad? This unit is just over 3 years old. Luckily the weather is not really requiring heat/cold, so I will wait till I get home next week to replace. Again Thanks.
  3. Just tried the breakers, it looked like it worked momentarily. Zone 1 did not show and error and only zone 2 showed the error. So I turned to fan on low on zone 1, and it comes on and then shuts down again. I'm a little tentative about doing a reset as mentioned above since I did not change anything that would call for a reset. Is this still something I should try?
  4. Thanks, I appreciate the quick reply, I tried it, however it did not work.
  5. I have two AC units on my Class A Newmar Baystar. I left the MH with the AC on and when I returned it was off. There is an E1 code with the zone 2 flashing. Research has indicated that this means the zone 2 AC unit is not communicating with the Dometic controller and thus neither will operate. I've tried powering off and on, including shore power. Should I climb on top of the MH and look to see if there is a loose connection at the AC unit? If so, do I need to remove the AC cover and is that easy? Is there any special precautions I need to take. Thanks-I'm just looking if there is an easy potential solution. Kimm
