Topic: 5n1 high temps fan IS running?

[daman]

My 5n1 Pro is showing high temps everything is fine when it's cloudy but soon as the sun hits it temps start to clime the fan is running I confirmed it many times it is NOT roof mounted it's not getting any radiant heat. I hear the fan running but it sounds like it's running slower can these motors over time slow down? I think if it was running faster it would draw more air up through.

I would recommend lubricating the fan motor, or replacing the motor. IT will never get any better, that I can guarantee if you just let it alone.

Yea I did all that I had it in for cleaning and inspection had it all apart lubed the fan shaft cleaned all dust etc, everything looks good, it just seems like the fan is not running fast enough. mine has the replaceable temps sensor do they ever go bad?

[DoctorKnow]

You said the temp & all is good until the sun comes out. That is a sign something is wrong with either the motor, wiring, or solar panels. Some have reported solar panel issues.

Does anyone know what these panels put out? I could try to get a reading.

I have the Pro with dual panels.

I have the same 5 in 1 that you do. If your 5 in 1 is in the sun its picking up radiant heat from the sun. I built a 6in thick insulated structure to inclose my temp sensor and have no more temp spikes like yours. Which means my temp sensor is located remotely from the 5 in 1 unit. If your interested in moving your sensor PM me and I'll be glad to share what I did.

Thanks you can PM them details sure. But I think I would like to try replacing the motor, anyone know a link to one that would work?

Here's my 5 in 1 with the fan running full speed compared to my tower sensor inside a radiation shield.  Thankfully I'm using the tower sensor as my primary temp/hum sensor when sending data.

  That's terrible, especially with a fan. Is your tower sensor aspirated?

Nope...just inside a radiation shield and is on the same post as my 5 in 1.

I see why so many complain about the 5 in 1 being in the sun. Wow.

If the fan is running full speed, then the air sensor is malfunctioning. Try taking out the batteries, slide the A B C switch around a few times, return it to original position, and reinsert batteries. Report back if anything changes. I think the rush of air must do something to these air sensors, because mine did the same BS for a while with high temps like that. I didn't realize what fixed it until much later, and that was doing what I posted above.

[daman]

Yeah something's going on if the fans full speed and you got temps like that.

Does anybody know what motor would be a direct replacement anybody got a link?

Just search for DC small hobby motors.

This one would be perfect I believe... https://www.amazon.com/1-5V-9V-Hobby-Motor-Solar-Perfect/dp/B01JLG80R8/ref=sr_1_31?ie=UTF8&qid=1499001830&sr=8-31&keywords=DC+small+hobby+motor

This one may work, but is cheap. http://www.ebay.com/itm/DC-9V-12V-6500RPM-Micro-300-Motor-Permanent-Magnet-Motor-2mm-Shaft-DIY-Parts/272737499644?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D41375%26meid%3Dae653d3105b54a0aacbcf50c57dd5c01%26pid%3D100005%26rk%3D2%26rkt%3D6%26sd%3D182326992648

Thanks Doc any idea what one would be better?

[DoctorKnow]

I would guess the first link, but I can't be sure.
