AC Charging Valve Location?

jme097jme097 Algonac, MIPosts: 1,203Member ✭✭✭
I have a refrigerant leak on my heatpump in my 280. Does anyone happen to know where exactly the valves are to check pressures and charge it? I open up the panel and all I see is the evaporator coil lol. Any help would be much appreciated.

    There may not be one but usually they're on the other side

    I know on my original AC/Heat system there was no valve to recharge, my new one does however.

    You can install a bolt on self piercing Schrader valve. Why Do You think you have a leak?

    Evap was all iced up and I had very little air flow from the supply air duct. Pull the return air filter and the evap filter and thawed everything out. Ran it again, had great air movement from the supply duct and it started icing up within 2 hours of run time.

    When it started icing up, what was the temp inside the boat? If mine runs 2 hours its damm cold inside.

    Also, is it R22? Or 410A?
  • jme097jme097 Algonac, MIPosts: 1,203Member ✭✭✭
    I don't know the exact temperature but I am bringing my Fluke Temp/Humidity meter tonight so I will know exactly and I need to calibrate the Passport control. I forgot to check the tag if it 22 or 410. It's original to the boat (2007) so I would say its more than likely R22 but will check tonight

    I doubt there is a leak. If its 410, all the refrigerant needs to be replaced as its a blend:)

    I work at Johnson Controls. I have a stock pile of refrigerant in my warehouse lol. Just need to find the schraders so I can throw some gauges on there first.

    If it's R22 they're on the left side, towards the wall. There's a suction and high pressure fitting - you'll need to be careful not to overcharge. It only good 12 ounces. Mine failed - I've got a Marin Aira unit now. 410A and blows 45° when the ambient air/water temp is low 90's.
  • jme097jme097 Algonac, MIPosts: 1,203Member ✭✭✭
    Yeah its R-22. Full charge is 10 oz lol. DIscharge air is 55 degrees which is fine. I think I have an issue with my actual thermostat itself. I calibrate it and it looses it calibration and the space temperature bounces all over the place on it.

    Now, try to find a replacement
  • jme097jme097 Algonac, MIPosts: 1,203Member ✭✭✭
    So the Passport 222000222 legacy stat is obsolete. Does anyone know if the newer Passport controls are compatible?

  • Handymans342Handymans342 Cape Coral, FLPosts: 6,518Member ✭✭✭✭✭
    Great Lakes Skipper looks like they have them
  • jme097jme097 Algonac, MIPosts: 1,203Member ✭✭✭
    Dometic makes the unit. I can only find the newer style control with the green lights not the older style red

    If you have to use the new controller, the board has to be replaced too. I think it was near $600. 

    When mine whacked out last year I just replaced the whole unit. Sooooo much quieter. Less cycling. Humidity setting.  Worth the cost.

    Why would you want the whole unit as compared to just the Tstat? That old one is heavy. Will cost a fortune to ship. 
  • Dude_HimselfDude_Himself Charleston, SCPosts: 332Member ✭✭✭
    But I can sell him the t-stat, control board, etc. for his. Everything but the cable - it's a standard console cable (not network).

    Sure can
  • Dude_HimselfDude_Himself Charleston, SCPosts: 332Member ✭✭✭
    Everything worked except the compressor - valve failure. Tried hitting it real hard with a sledge - no luck. Unit is 10 years old, but freshwater only and looks brand new - no rust anywhere. Boat was in Ohio - I doubt the AC was needed honestly - they probably ran the heat more.

    New compressor is $150, tools around $300. I will probably try to fix it this winter when I have time and the air isn't trying to smother me to death - for fun - then sell it. Or keep it as a spare. I bought a new Marin Aire and dropped that in - it's awesome. Soo soo cold.

    Disassemble and sell the parts. 
  • jme097jme097 Algonac, MIPosts: 1,203Member ✭✭✭
    I was referring to the stat lol not the failed compressor LOL
