I presume you meant T0 works fine, as that's what's in your subject. If not, I'm confused.Quote

However, the T1 pin works just fine and connected the bed thermistor to this port works OK.

There are analog pins in Aux-1 and Aux-2 (diagram). You'll need to duplicate the circuit as it appears in the schematic. If you want to know why, read here.

No, I meant with the resistor and capacitor. Look at the schematic under the Thermistors section. There's actually 3 duplicate circuits there, one for each thermistor. You''ll need to duplicate one of those with the correct value components in order to get a correct reading.Quote

by duplicate the circuit do you mean to simply connect pin 1 to VCC and pin 2 to GND? Or is there more to it then that?

How can you kill an analog input?
You must have fed the thermistor pin with negative or >5V source? Did you short the 12V heatbed wire with the thermistor?
