If the fridge wood is wet there’s a likelihood the water ran down from roof leaks, but Lexel should work around the vented side cover edges if you see compromised sealant there. Flowable Dacor is best for most roof seams, but like Dwight notes, the key is getting the area clean of dirt and old sealant; to seal well, any product has to get a strong purchase on the infrastructure surface, not the crud covering it.
I use Lexel everywhere, coach or home, and for sealing outdoor electrical devices since it’s non-conductive. It acts and applies more like silicone, but seems to be an overall better and more universal product. Recapping the tube’s nozzle tightly is critical though, as after a month or so of storage the first inch or two of Lexel will thicken and it’s difficult to use until the more flowable stuff gets to the tip. Then a wet finger works well for making a neat and smooth concave spread of the fresh Lexel bead, so its width grabs more adequate surface.
