Thanks for the info DR650,
I've got two of the older style in my MH. After so many years of being a family owned business that stood behind their products with a lifetime warranty and quality products, it's sad to hear where Dometic has taken the line. I was a fierce supporter of them for years. Many years after buying my previous MH that had one fan above the kitchen sink (that made a terribly annoying ring when it ran) I stopped by their table at a FMCA rally and asked what to do about it to make the wife happy. They asked the year of the RV, I told them it was a 2001. Then they handed me a new motor assembly and asked if I could do the replacement or if they needed to send a tech out to do it. I told them I could handle it. There was no charge and I got to keep the old parts - still around here somewhere. They said a one time (back in that time frame) they'd gotten a bad batch of motors and had heard that complaint from several owners.
Times have changed from what I'm hearing. After many years in the business, it was time for the original owners to retire and they sold the company to Dometic. The rest is history. These days we're dealing with a corporation that has a profit motive as their paramount driving force.
