My a/c is leaking from the ceiling of the rv. i cant tell exactly where, but something isnt draining properly. does anyone have a clue as to what i can do about this? my rv is a 1989 model. the a/c is cold and runs great. it has only recently started this leaking.

Hello. That flashing combo of lights is an error code telling you that something has malfunctioned. Most likely, from what you describe, the drain pump is clogged or jammed. I need the model number for a more exact diagnosis of the error code--its a digital code--the lights will flash a certain number of times, usually. The clue here is the water left standing in the tub. It means the drain pump failed to evacuate all the water out. When you cancel/drain, do you hear the drain pump turn on? If so, then the main board is activating properly and sending 120volts to the pump. Probably the pump is clogged with food or debris, and/or the drain hose is clogged. If you don't hear anything, then the kick panel(below the door) must be removed, the pump, wiring, main board must be checked. Check the filter inside the floor of the washer--if it's gunked up, the main pump can't spray properly and the drain pump can't pull water out.

Where exactly is the condensation??? If anywhere inside the refrigerator like on the walls and packages or excessive frost of freezer packages, you probably have an air leak from one of the doors at the gasket area. Check doors for proper seal and no cuts or breaks in gaskets.

Fresh batteries in remote? Will AC turn on by manually at ceiling assembly? Little green or red light on at ceiling assy? Have you checked Carrier site for manual to download?

Normally, the condensate will drain out of the unit onto the roof and off the edge to the ground. Remove your cover inside (probably 2 screws) and tighten the 4 bolts you will find inside. If they are tight, go to your RV supply place and get new roof gasket. Remove the AC and insert the new gasket and resecure the AC to your roof.

Thanks for your question @ FixYa.com

If it's leaking inside where filter cover is, then real good chance the drains being plugged is the only problem. If water (condensation) not running off roof when operating in cool mode, then I'd bet drains, which are located under unit on roof, and you should see them sticking down like buttons. They have a hole in side that needs cleaning with a pipe cleaner or similar to open them up. If need be, shut off power to unit and remove top cover on roof unit and look for the drain holes in base, and clean them out. If water comes in while raining, but AC not running, then it's gasket. That is remedied by removing ceiling assembly (just screws) and 4 bolts that pull/hold the upper and lower assemblies together, unplug wiring to upper unit, and simply lift it off, change gasket and re-install. Tighten those 4 bolts equally when gasket is aligned properly over hole, only until gasket is approx 1/2, original thickness. Plug harness back in and your done. (about an hours work.) Only other thing that may be wrong is styrofoam drip tray for cooling unit, under cover on roof may have a crack , allowing condensation to leak in. If that 's the case, you can try to find a sealant compatible with styrofoam to seal those cracks.

Does the unit work other, than the leaking?If it does you need to install a square seal between the ac unit and the roof.You can either buy the seal from Ebay or I would recomend an Rv Repair place.(They Might even be able to install it where the Rv Sits)

You need to find where the drain is. The water should flow to a drain and not into the unit. Once you get the condensation draining properly you can use a good quality silicone to seat around the unit. You might check at a RV parts place and find a product they recommend for RV roofs. Hope this helps.

The upper unit itself is not ducted. They are all the same. The ducting is done with the lower unit or "Ceiling Pack" of the air conditioner. You need to see your RV is ducted, ie...vents in the ceiling that blow the are out. Usually they are round and mount into the ceiling. Another way to tell is if the unit has a wall mounted thermostat.

Hope this helps,

dont lay it down,,,,stand it up and lean it back than fill with water,,be careful use a prop..another way is to slide news paper under unit,,than we can tell what area its leaking from..unit make only leak in drain,,so we have to test unit in drain to ckeck that system,,onthejob
