Swapping Thermristors (Bed/Extruder)

Hello all!
My brand new FolgerTech 2020 I3 printed one nearly perfice 1cm cube today before the thermristor in the extruder promptly died. It will be monday before I can get a new one and I hate to loose a whole weekend of calibrating and tinkering. Can I steal the thermristor from the heated bed and put it in the extruder? I can at least play with some PLA without the heated bed. Can anyone help me identify these two thermristors and tell me if there are reasonably swappable?
Thanks for the help.. PS even though my first day had some issues, I LOVE this hobby!
The first is the dead extruder thermristor


Next is the one from the heated bed

I would imagine they are the same, but check the Configuration.h in Marlin as to what type they are defined as and change if necessary:

An example...

#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_BED 1

Great tip! that was exactly what I was looking for. They are both defined as type 6. I ordered these as a replacement:
Amazon - 100K ohm NTC

Now I have to figure out what type number to put in when they arrive.
