Dometic Penguin II Install Fail

"I suggested they contact Newmar". Didn't need to read any further.

It always pays to do your homework on any issue rather than to depend on a "technician" to do everything right on a repair. A lot of shops have a large turnover on labor so the "technician" that you get may be nothing more than a rookie that is getting his "on the job training" at your expense.
I should add that it is always a good idea to educate yourself as much as possible about any issues with your RV, your toad, or even your own healthcare.
Glad that everything turned out well in the end.

That gasket has nothing to do with water intrusion. That gasket just separates the INTAKE(hot air) from the Exhaust(cold air). That gasket is NOT special. When you do any type top down AC gasket or AC replacement, you use an EXTRA AC gasket. Cut out the one side and fit as your pic shows to separate the intake from the exhaust. Now, the 4 blue squares I will assume are the gasket pieces that go between the bottom of the mount pan and the roof, with the mount lag bolts going thru them. THAT seals the AC unit lag bolts when the AC is secured down. I will bet, THOSE 4 squares were not used and they just ran the lag bolts into the roof. Now, $120 for that kit. The extra Dometic AC gasket COMES with the required parts for about $20. You are right, a QUALIFIED TECH and shop would have done the job right for about $100 less in parts. I always advise my customers, IF the shop has no knowledge or has never done a particular job, GO ELSEWHERE. Find a Shop that HAS knowledge of that product. Doug (working on Newmars for 27 years)

Doug,

I PM'd you about a month ago about the malfunctioning AC that I just replaced. You advised me to disconnect the AC's thermistor which I did. However, after doing that my CCC2 thermostat returned an error and locked up.

That really didn't bother me. What bothered me was your reply -- "I guess the new control boards (CCC 2) error on the freeze sensor". You guess?

It sounds like you have some gaps in your knowledge -- maybe with just the newer technology -- but you come across as being absolute certain.

I am ALWAYS learning. The electronics in RV's change all the time and NONE of the OEM's or suppliers send out notices about when they change the parameters. Sorry, my gap in knowledge has caused you problems. I guess you got what you PAID for:B Yes, the NEW CCC2, parameters monitor the various sensors, as I found out from YOUR post and reply. The OLD 5 button CCC did not monitor the various sensor parameters. If you feel that my experience and knowledge are lacking, just don't ask or use my posts for help. I can easily not respond to any posts you ask for help on. I AM certain on 99% on my posts. Unlike others, if someone points out a error, I WILL respond with an acknowledgement that I was in error.
