Quit working a long time ago, i just put it on recirculate for ac. When I push the button the light comes on, but as soon as i release it it goes out. I can take it apart, but if there is nothing visibly wrong with it i dunno how to fix it. I'm a real dummy when it comes to electrical stuff.
Took it apart, found it's is all burned up inside. I'll buy a new one...problem solved
