Thermistor replaced and temperature not reading properly

[IMC3D]

While building my H1.1 printer(RAMBo) I had 2 thermistors, 1 for the hot end and 1 for the heat bed. I accidentally broke one during the build, so I ran my printer with the thermistor for the hot end and everything worked pretty well. Now I want to get the heat bed working so I ordered at thermistor from ultimachine.com. It came braided so I decided to replace the thermistor in the hot end with this new one and put the old one on the heat bed.

Well my temperature is reading 476 degrees while the hot end is off, so something is not right. Is there a way to change in the firmware the type of thermistor the machine is using? Or should I just order another thermistor that is the same as the old one(Semitec 104GT2, I think)?

This is what I ordered from ultimachine.com:

This is the configuration.h and I have tried all the different settings but none seem to work with this sensor.

// What type of sensor is used?
// 1 is 100k thermistor (Epcos B57560G0107F000 - RepRap-Fab.org and many other)
// 2 is 200k thermistor
// 3 is mendel-parts thermistor (EPCOS G550)
// 4 is 10k thermistor
// 5 is userdefined thermistor table 0
// 6 is userdefined thermistor table 1
// 7 is userdefined thermistor table 2
// 50 is userdefined thermistor table 0 for PTC thermistors
// 51 is userdefined thermistor table 0 for PTC thermistors
// 52 is userdefined thermistor table 0 for PTC thermistors
// 99 Generic thermistor table
// 100 is AD595
// 101 is MAX6675
#define EXT0_TEMPSENSOR_TYPE 1

Thanks for any information anyone can give.

Make sure your thermistor isn't shorting touching any other metal, I thought that the thermistor for the bed was blue?(Original one with the velleman) What you ordered was a thermocouple, different from a thermistor.

Thank you for your reply. I ordered the new thermistor from mouser.com, so I am about to install it and hopefully I will be back up and running soon.
