Aft ac unit works great. Front no. I have been told that there is only one seacock, strainer and pump for both ac units. Water flows through but front ac thermostat error message "ps" and "hi" after it is on for about 2 minutes. suggestions?

High pressure, could be several things High pressure cut off switch, clog in a line, compressor. Probably going to need an a/c guy for that one

check water flow of that unit. try running with second unit off.

getting water with only that unit on.

Each unit has its own water discharge correct? and water in coming out of the discharge of the unit in question?

i only know of one discharge and it is discharging. Is there a second discharge?

I believe so, trace the hose from the outlet on the unit. Should be very close

the bow unit is buried underneath the bed and the only way i can get to the discharge line is to remove the unit. Think i will continue to try and find and AC repairman. Had no luck so far

I have the same issue with my 2001/2002 Martinique. 3700
i switch out my touch panels with the aft to confirm it was not the panel themselves.
(you tube has info on bad panels)

i'm small enough to venture under my bunk this summer.. but too fat to enjoy it.
good luck

discovered that by taking out the drawers i can then remove the panel that allows access to the aft unit pretty good. we found a loose wire was my problem
