Maxxair VENT 0004000K

I purchased this fan for my Class B, it worked for two days. The next day, it turned on by itself and never stopped. I had a technician look at it, turned out the circuit board went bad and needed to be replaced for 50$ approximately. I can't return the item sadly cus it has been installed already. I managed to buy it for half price, no one wonder why it happened.

Product looks great, and worked well for about a month, until something changed. Now when I turn it on, the fan starts spinning for a few seconds before it stops and the machine starts beeping loudly for a minute. I've read all the troubleshooting suggestions on the internet and tried multiple things to reset and fix it, but nothing has worked. I didn't do anything to effect the fan or circuit board in any way. I believe the circuit board needs to be replaced which I have contacted Maxxair about, but I'm not optimistic since I ordered it through Amazon. Take caution. Once you cut the hole in the roof and install the fan, you want to be sure it works! Having an opening in the ceiling isn't that bad, but I could have done it much cheaper myself.

I have installed Fan-tastic fans on RV's for years. This time around I thought I would try the lesser known Maxxair fan. What a pleasant surprise! Significantly less expensive than the comparable Fan-tastic fan, 10 forward and reverse speeds and the ability to run the fan with the vent closed for interior air circulation. The controls are digital and easy to operate. The fan is almost completely silent when used at speeds 5 and below, getting louder as speeds increase but never to the point of being irritating. The integral thermostat is accurate and shuts the fan off at the selected temperature. Installation is identical to the Fan-tastic Fan - not difficult but time consuming to remove the sealant from the fan being replaced and the RV's roof. For those of you who are aware of the forthcoming Zombie Squirrel Acropolis, this vent locks from the inside providing another level of protection from the zombie squirrels.

Perfect. Installed in my camper and worked well

A great fan. Moves a great deal of air even on the low settings. Very quiet compared to the 3-speed fans and the reverse switch creates a lovely breeze.
