Hi Guys,
Just completed my first Heatermeter build and everything seems to work great with the exception of the blower output voltage. 12V is getting in but it will only output 1.2 V regardless of the software settings I change on the fan.
My first thought is that the MOSFET is bad, so I did a NPN transistor test with a multimeter and it seems to be good (although that was in-circuit so could that be giving me false results?), so now I am thinking the issue might be more upstream.
Not the most circuit savy, so any ideas on where to start would be appreciated.
Thanks!
Chad
