Mintemp triggered can't get rid of it

After fixing my elusive Z offset, my Smartrap was printing very well again.

This morning I decided to print something.

It ran perfectly for 30 minutes, and then stopped.

The error messages in Pronterface told me that Mintemp had been triggered.

The LCD display says the same.

I have removed the thermocouple and the thermistor from the hot end. LCD says room temp is zero.
I have unplugged the the thermocouple and the thermistor from the board.
The LCD still says Err:MinTemp.

Has something blown? I can't get rid of the message. The printer has had minimal use, only printed around 6 small items??

Quite sure there is a fault in the wiring of the thermistor, maybe a loose plug or soldering in one or both the wires.

I just got the multimeter out. 4.94v at the thermistor pins on the board, but no temp detected. Started moving the detector end around and the room temp appeared. Looks like a broken circuit at the busy end, so will have to order another I guess.

Order more than one, trust me...

I did, lol, I like to have spares of everything, it's a bit frustrating when I can't print for the sake of a fault.

That's the point: I also had so many faults (power supply, RAMPS, printed parts, cables...) that I have spares of literally everything.

LOL, Me too... That's why I keep building more... I think, well I've got enough extra parts to build another whole printer... then I buy extra parts for it... and the cycle continues...
