build plate not heating up

[CrazyL 1]

Greetings

 

New to the forum so please bear with.  I have a 2+ extended.  It has been working ok up until now for what I've been doing.  however, it's developed a problem which I don't know how to overcome.  The build plate basically stopped heating up. 

: The 1st time it did it, it threw up an error code of ER02, and told me to investigate.  I checked the wires were screwed in to the plate properly.  Then I tried again.

: No error but the plate still didn't warm up.  When I go to advanced and select heat build plate.  The screen says what the temp is, slash, what you want it to be be, right!  The temp reads 78 degrees, and when I wind knob to 100 degrees, it warms up to a tepidness and I can rest my hand on it.   So that's wrong for a start.

: Swapped temp plugs over.  now temp reads 19, on the left, but doesn't get any higher, and on the right, I can wind it up all the way and the plate gets hot.

: The nozzle doesn't get hot however, and reads like when plate  is plugged in to that part of the board, reading 70-80 something when it's normal room temp and not getting hot when I ask it to.

 

So, is my main board knackered?  I ask because it all points to that temp sensor socket for the plate.  Not a big electronic whiz, but I can get by with basic stuff.  if it's the board, do I have to install firmware upon fitting a new one?   I genuinely don't know.  Any help is massively appreciated.
