Leaking air conditioner

After it rains, not during, one of my ac's blows water out when it clicks on for a minute or two. It doesn't do it until the unit kicks on. I cant find any cracks in the caulk on top of Motorhome.

Thanks,

Steve

Evaporator drain is probably plugged.

I'd generally agree with this assumption. First is your RV, Unit level? Is the air filter clean?
If you're not comfortable performing rooftop maintenance on an electrical appliance get qualified assistance. Unit power off.
Popping the external shroud open, there will be small drain ports in the bottom of the evaporator fan coil housing. These allow the condensate water to run out of the internal drain pan to the external drain pan area. There should also be ports in the external drain pan. Clean any debris out of these areas. Make sure the water can flow down out of this area and off the roof.

Best of luck

Caulking...........?????

There should NOT be any caulking used for a roof top A/C Unit
A/C Unit is sealed using a roof gasket.

Evap Coil is under a 'sealed' cover under the shroud.
Drip pan has drain holes...if plugged condensation can overflow form drip pan and/or get pulled over by fan wheel

OR
A/C Unit hold down bolts are loose.
Remove ceiling grill cover....in each corner will be a small bolt head. They hold A/C Unit on roof. They can vibrate loose so that roof gasket isn't compressed
Tighten them but just SNUG.....too tight and you will crush roof gasket/warp it and then it would seal properly either
Too loose/too tight----makes roof leaks possible
