air from AC escaping into the ceiling cavity
My camper has developed sort of a stale smell that was only occurring when I ran the air conditioner. I cleaned the coil and duct work and all parts that contribute to air coming into the cabin, yet the smell was still present, but only when I ran the AC. Finally, I removed one of the ceiling light fixtures and there was a bunch of stale, dusty smelling air coming from the hole in the ceiling for the light. You could feel the air coming out of this hole with the AC running. It's not exactly a mildew smell, more of a stale dust and sawdust smell, which is logical, since there's a ton of sawdust and stuff in the ceiling cavity from the construction of the camper. I have thoroughly checked the camper and there is absolutely no evidence of a leak. Here are my questions...
1. I've had the camper for 6 years. Why is this now occurring?
2. Is it normal for some air to be escaping into the ceiling cavity when the AC is running? If not, how do I stop it? I don't want stale air from the ceiling void space to be pumped into the cabin area from all of the light fixtures.
3. Is it possible to seal all of my light fixtures to stop the ceiling space air from getting into the cabin? I thought about installing some sort of vent tube from the roof into just the ceiling cavity that would allow the ceiling void space to vent to the outside.
What is everyone's thoughts on this? Thanks.
