Fantastic Vent Baseplate Warping … has anyone seen this?

[Charliesmom]

I had a Dometic Fantastic Vent 3350 installed when our Transit was built out 2 1/2 years ago at then SMB West. I’ve noticed that the ”plastic” baseplate is now warped. The fan works perfectly, doesn’t leak and is not too loud. I spoke to Dometic Support (Fantastic Vent has a limited 7-year warranty) along with sending pictures of the baseplate. Their response: “After reviewing the photos provided and advising with our person here who specializes with the fans this would be caused by the heat of the sun. Unfortunately since this was due to the elements rather than a manufacture defect we would not cover the cost of replacement parts under warranty.”
Granted, we live in Arizona, but there must be thousands of these fans on vans and RV’s that are stored in hot climates during the summer months that haven’t reported this issue. I don’t have it in a roofed enclosure but do keep the van covered when we are not traveling in it. The baseplate piece that needs replacing is not available to purchase without all the component parts, i.e. Motor to raise the cover, circuit board, switches …. Basically, the guts of the fan.
Has anyone else had this problem?
Since it’s not leaking and the fan works great, my feeling is to do nothing at present and see what happens. Thoughts?
