Smelly vent under kitchen sink

I keep getting sewer smells in the kitchen cabinet under the sink. There is a vent under there. Is there anyway to fix the smell?

Air Admittance Valve. Replace it yourself.

The air admittance valves in most RVs are very cheap and fail easily. I just replaced mine with these


You can get new valves at any home supply big box store. Avoid the cheap ones in the $6 range. A good one should be $25.

Unscrew old one and screw on new one. Takes a couple minutes.
