23 Vent fan front and back

Dumb question.
How do you operate them?
I had the propane heater on for 65° and wanted to air out the trailer a bit. It's been raining last couple days but has been clear all day.
So I go to press "on" it opens then closes. Then doesn't open again. I have the fan speed to zero and have the fan switch to on. All of which is a moot point because it doesn't want to open at all.
I try the one buy the bathroom. Doesn't even open. I press then wait. Nothing.
I have the dial on the neutral setting as I don't need heat. Sometimes they open but don't want to close and I have to do it manually.
I'm very frustrated with these fans. The videos aren't any help. The guy make it look so damn easy. Just goes over and presses the on switch and it works. Not for me. I can't even get them to open tonight after five minutes of pressing every (TWO) button and a temperature dial.

Well it was a clear blue sky day today and the fans operated fine doing the following.
Switch the fan speed from zero to one.
Turn on the fan switch.
Turn temp to cold
Pressed the black power open button.
But then it wouldn't close once I hit the black power button? I had to manually close it
obviously turning the motor in the process.
I hit all the switches and turned the temp to and it wouldn't close.
Can't figure this thing out.

Here’s my best guess at your problem.....

The fans have Rain sensors. Just under the edge of the lid. If these sensors get wet in any way the fan lid will close. This is to prevent you from accidentally leaving them open and getting rain inside your unit.
The fans have 6 (yes I said SIX) switches to operate them
#1 Fan on-off switch. This switch activates 12 volt DC power to the fan motor
#2 Lid open-close switch. This switch actuates the fan lid up and down.
#3 Rain sensor. This switch overrides the lid open-closed switch if it becomes wet.
#4 Lid position switch. This switch disconnects power to the fan motor when the lid is closed, preventing the fan from running without air flow.
#5 Fan speed switch. This dial controls motor speed 0=off 1=low 2=med 3=High
#6 Temperature switch. This switch allows you to roughly control at what temperature the fan turns on an off at.

So with that said... for the fan to operate these things need to happen
#1 fan lid has to be open. This means that the rain sensor must also be dry.
#2 fan power switch must be in the “On” position
#3 fan speed control has to be on 1,2,or3 setting. (If on “0” fan will not work)
#4 Temperature control must be set low enough for it to allow the fan motor to operate.

NOW. About manually operating the Fan Lid with the Spin Dial.
You should not turn the dial with it engaged with the lid lift motor.
You should disengage the Spin dial.
To do this “pull” down on the Spin dial and then you can rotate it with out the resistance of the lid lift motor. To re-engage the lid lift Spin dial to the motor push up on the Spin dial ( you may have the slightly turn the dial while pushing up on it to get it to re-engage with the splines of the lid lift motor.

The "fan speed" switch turned to 0 turns it completely off. It won't open. Set the fan speed switch to 1.

The small black switch opens and closes the vent. It does nothing else.

The big black switch is the fan power switch. All it does is turn the fan on and off. It has nothing to do with the vent opening and closing. If this switch is turned on, and the vent is open, then the thermostat knob determines if the fan will run.

The thermostat knob is what you use to determine if the fan auto turns on/off. It is temperature dependent. It has nothing to do with opening or closing the vent. It only turns the fan on/off.

They do not auto-open. They only auto-close if the rain sensor detects moisture.

They do not heat. Turning the thermostat knob to the hot setting only means that it must be hotter for the fan to turn on.

Personally, I keep my fan speed dial set to 1 so it will work, but at low fan speed. I keep my thermostat knob set to completely blue so if I turn on the fan it will work. When I want it off, I use the fan switch to turn it off. I use the small toggle switch to open/close the vent. I use the big toggle switch to turn the fan on/off. I ALWAYS use these settings and don't let the fan auto-anything except for the rain sensor.

Vent fans

We have a 2017 23D with the 2 roof fans. At first my fans would close at the first hint of any rain. So I installed the Fantastic Fan covers with the bug screen. This should have made these fans a bit less sensitive to a bit of rain. Not so. If fan was on and you even sweated inside the dang things would close. One call to Manufacturer and a 5 minute conversation with nice lady that answered call told me how to eliminate rain sensor. Problem solved. I can leave my fans on or just the cover open and it has to be raining pretty hard before any drops of water come in. Read your instruction booklet on how to operate. Takes 5 minutes per fan to disconnect rain sensor. Love the fans. The rain sensor not so much.
