I am a confirmend weekend warrior wanting to learn all I can. A couple months ago I was assured I can add a vent fan to a light circuit. So ahead I went but the vent fan does not respond. The lights work ok but not the fan. HELP please.
The ceiling fans in our ‘15 RB are triggered on by plunger when the roof vent is opened.
I’ve no idea if your vent is like ours.
When our vent fan would not turn on, I isolated the problem to the plunger/switch and replaced it.
Just a thought.

Verify 12V on your power source then check to make sure the T stat on the fan is closed as well as the limit switch. Lights and the fan together might not be the best choice.

on my LD RL the fan is tied to the same line as the lights so that should not be an issue. get a multimeter and make sure the right voltage is feeding through
Hi; In my '99 LD all of the wiring is 12 ga. and easily can accommodate the current demands of roof vent fans. As stated, the temperature control needs to be dialed to the lowest temperature to enable the fan to come on. If the fan is like my 'Fantastic' fan, both the speed control has to be other than '0' which is 'Off', and 'IN' or 'Out'. The center of in/out is off also. As Kent said, the cover has to be open a few inches to allow it to run. Red wire to +12vdc. and White wire to ground. Your picture looks like it had a black wire. In the older days, and your '89 might qualify, the black wire was the ground, and the red wire is the +12v. A meter will tell you which is +12v. If the lights work, then there is power there.
The vent you are using; did it have a fan before?, or is this a new fan. RonB

New fan.

Finally got 'er done! Thanks all for your insight.
