Question: SX350 too hot warning

[vikodin]

I built a SX350 box mod 2 weeks back and it doesn't leave my hand now, Its my baby and has been vaping beautifully up until last night.
I spilled juice down into the varitube 510 and after that I was getting the "too hot wait 10sec warning"
So I dried the 510 out and checked inside the box which looked dry, also checked the board for dry solder joints, overheating signs etc but its hard (impossible to check it all in my cramped DIY box) .

Bloody thing continued to overheat so started to panic a bit.
Next thing I thought I better change my coils on the RDA as they were 2 to 3 weeks old and had just gone from .78 to .85ohm in the last 24hours.

Wound a beautiful dual .7ohm coil juiced it up and vaped away
Its now 24hours later and it hasn't failed since the coil change.

But its got me wondering what it was and concerned the too hot warning may return.
Was it really my coils?


So who else has seen the too hot warning and what caused it on yours?
Has anyone else had a similar issue?

I havn't experienced the too hot warning myself, but i have had issues with 'check battery' and 'short' both of which were fixed by getting a more solid connection between atty and 510. i've had no problems with a chip itself.

That's a new one to me too. Never heard of a too hot message. Maybe if it does it again, check to see if anything is actually hot in the box.

Its the chip that getting too hot. Impossible for the chip to read any other temps. How many watts are you vaping at and is it the original wiring ??

Someone on a Facebook group called sx350 modders says

" I experienced this ONLY when I had hot glue over ANY of the components on the face or the back of the chip.....When you cover ANY of this you will get that error message EVERY time...Depending on How Much of the chip you have covered up will depend on How sensitive it is...Covering the components Acts like a blanket and throws off any temperature sensing components. The FIX to this is uncover any and all area that you have covered. And I see you have a big portion covering the front of the chip....Un cover that."

Someone else said

" I once gotten that as well. Take care not to put to much glue over the board itself, you could cover the temperature sensor, and it will give you false readings."

Also, he thinks one of the smaller chips on the board is the heat sensor, maybe the 3 pin?

Yeah I couldn't find anywhere it felt hot on the board

Vaping at 35w normally but have used it as high as 50w without issue, good thing is it hasn't failed still since I rebuilt the coils but maybe there was some juice on the board that dried itself out.

Cheers for the replies guys
I did post on that FB page but got next to no response.

About the glue, apart from the factory glue on the board I didn't add any glue or epoxy myself. My board is held in place simply by the tight design of box, positioning of the wires, switches and a tiny bit of tape. (it doesn't move)

Maybe it was a touch of juice that got in there and has since dried off if thats the case.
It hasn't failed again so here's hoping its all it was and at least the boards protection is working how its supposed too.
