Tighten the four mounting bolts from inside. You will find them loose.

I have replaced both of my A/Cs. After a month you need to tighten them again. The foam seal collapses.

I did mine a little while back - nothing to it. You can get the deals anywhere. If memory serves they are 14x14 and everyone makes them. More/less you flip the breaker, unplug the unit, undo the 4 screws you tightened, go up on the roof and lift or flip the unit over. If you flip it over, remove the plastic shroud.

At the point you will see the seal. Remove the old one with a gasket scraper/whatever. Clean the sealing area with soap/water and then stick the new seal to the AC unit in the same place as the old one. Flip it back over (place the AC unit) and go inside and shift it around until you can get the 4 bolts back in. They are not supposed to be really tight. More less hand tight and a tiny bit more. I think 40" pounds?

They are easy to do. Once you do one you'll bang out the other one in 5 minutes.

yes, be careful, they caution not to tighten too much. they have instructions. compress to no more than 1/4"
or something like that. very easy to do 4 long bolts. If you have someone help lift it to the side on the roof it's quick. not very expensive to just replace the gasket no sealant! just compression seals it

I was looking on line for the Roof Gaskets and happen to see on Camping World site which shows three different vendors Gaskets ranging from about $25 to $60. These were Camco at $38 as I recall and a universal one by Camping World at $25 and another Camping /World at the $60 rate. Any one have a best guess as to which product might be the best to invest in??

This is what I bought. It is a 1 piece gasket where the others are sections which are glued together.
