Replacement RV Roof Vents with Rain Sensor or Rain Shield


Have bathroom fan that does not close when rains, I have cleaned the rain sensor and does not work, is there a program that I might of turned off by accident? The other two turn off when rains and this one did for a while new trailer DRV Mobile suites 40 foot 2017. This is wall switch four buttons the kitchen works with remote and it closes when rain. Can I program wall switch to turn back on ??? If does not work will have to replace the whole fan ? or can I buy a sensor and put that on?? Thanks , You guys and gals are the best


Expert Reply:

The roof vents that have the rain sensor feature (to enable automatic closing of the vent when it rains) are not serviceable. The rain sensor element is integrated into the vent/fan. As for the wall control panel in your RV you will want to speak to the manufacturer (have your VIN handy) since we do not have information on such OEM switch setups.

If you want to replace the vent unit you might consider the MaxxAir # MA00-07000K which has a rain shield, or the MaxxAir Plus # MA00-04500K, both of which are made for 12V operation.
