Temperature and heating error correlation

Hardware, PWM, and Optics

Hi there!

I keep on getting this message when running a self test:

Any idea of how to proceed?

Thank you!

it looks like your heater PCB isn’t receiving any power (a DC voltage is being applied, but there’s no increase in temperature). Were any modifications made to it (software or hardware)? Try reconnecting the wires from the HAT to the heater PCB?

Ummm… It could be that I just replaced the heating extension HAT? Is the problem on the PCB or could be that HAT issue?

Thanks! :wink:

Hm, and you installed the associated plugin?

Hm, I wonder if I ever tested self-test + the temp HAT. If you start the thermostat, are you seeing anything unexpected?

Hi Cameron :slight_smile:

Doenst say anything but then it doesn’t raise the temperature…

The pluggin is installed

hm, I’m not too sure. Just some ideas:

  1. Does it work again if your remove the HAT?
  2. Any visible damage to the heater PCB or cable?
