But I'm not sure if there is a way to test if your mainboard fried.

I was cleaning my e3d V6 hotend because I forgot to turn on my extruder cooling fan yesterday, and after I re-assembled the extruder, I powered everything up and ran the clean nozzle function. The printer heated up and I took a brass wire brush to the nozzle, when i did this, the lights flashed and the printer restarted.

I'm pretty sure I shorted out my mainboard because ive tested two different thermistors and the main thermistor has been stuck at 137C the entire time, the bed thermistor is stuck at 120.

Is a there a test I can do to see if I have fried my mainboard? Ive tried reflashing RH as well to no avail.

If i have fried my mainboard, is there a way anyone knows of to which i can aquire a replacement without buying another $300 printer?

Thanks
Andrew
