Thx

Replace the thermistor if they’re damaged

Very clever!
The thermistors are OK for christs sake!!!
The port is always showing the same temperature!!

Have you reset the arduino? After that I’d be checking the circuit. I’d look but can’t atm.

Now settle down and get your multimeter out.

Well if you’re a mechanic and don’t know wiring then I don’t know what to tell you.

I’d say it’s unlikely they are fixable. Unless they are shorted to ground, or one of the passive components on the port has fried (possible but unlikely), the port itself is damaged, which means you would have to replace the microcontroller.

Just go buy a new Ramps shield. They are so cheap on eBay and I’ve never had an issue with mine and it was $10 shipped from the US. At some point it’s not worth the time to trace a bad connection etc.
