My ArGo crapped the bed overnight, trying to turn it on this morning and got the Error5 off message, seems like heater won't start, tried a couple of different batteries and all the same, so sad.
I was using it so much that I was starting to wonder what it's the life of the unit, will need to go back to the SOLO and I touch wood it doesn't broke too.
Edit: heaters are lifetime warranty, but I live in a crappy third world country so, I don't know.. I contacted the seller, unit was purchased in September 2019.
Probably not even the heater, if the unit is not heating, the issue would be somewhere else, and that is not covered by the lifetime warranty.
There is a very quiet sound the unit did when working, probably the PWM, sounded like clicks when heat was on. Now it's not doing it.
I will wait for the seller response, but on a negative, I will try to either fix it, or hook it up to an arduino and DIY my way up to a working unit. I will be sharing any progress, maybe on a separate thread to not bother too much here.
Edit #2: I disassembled the unit, cleaned it with alcohol, and now it's working!
