Been a long day. Got a lot done. Only have a few minutes before dinner gets delivered.
First is a question: Does anybody know where the "Freeze Detector goes in a newer Dometic AC? I found one hanging down on a wire after I lifted and blocked the AV to clean the old roof under it. It has a clip to hold it onto a round pipe and I assume it goes up inside the coil area. Just not sure where.
Here is what was under the ladder mounts at the top.
One of them had not leaked and was only loose because the big screw that holds the fitting to the tubing came loose. I have to use loctite on those after this. The screws were still solid into the wood.
The other had leaked quite a bit. It was an infested gooey mess but it had not gotten to the wood much. The water had flowed between the layers which has both come loose from the wood. It then went down the back and caused the window leak in the back. I figured that was the case. I epoxied the area and the layers with an epoxy glue additive and thickener from West Marine. Love their stuff. Here are the materials.
I put the thickened epoxy glue between the layers and also the wood. I covered the exposed wood and then put bricks on the rubber roof parts where I glued the layers. Here it is an hour later.
I covered it with Eternabond after an hour. The Eternabond sticks immediately and does not come loose when I clean the area with alcohol first.
I removed the old TV antenna. I had suspected it was leaking and had no use for it anyway. I'll save it in case the next owner needs it.
I was right about the leak but luckily it was between layers for the most part and no rot. I put an electrical plate on the ceiling and shot Dap Medium Expanding Foam into the holes. Then I cut off the excess on the top and used a bit of vinyl siding and some caulk to cover the hole. Eternabond completed the job. Not as pretty as I might have liked but waterproof for certain. The brick is holding the vinyl flat until the caulk sets.
I raised the AC with some blocks to clean under the edges and get a look at the old roof under it. The old roof is great. I cleaned it up and reinstalled it. I will just brush the roof under it as far as a brush will allow. I didn't want to leave it raised because a s. Florida rain could make a real mess of the inside of the coach.
Dinner is here. I.ll post more in the AM.
