GW Micron 50

[Agile]

I went to one tonight which seems to be inoperative as a result of a high resistance NTC. It measures 44 k when at about 28 ° C.

What should it be? Applying 10 K across the connections brings the boiler on !

The NTC is screwed in with a clamping male screw. Can anyone describe with dimensions what the NTC element actually looks like?

Sounds like you are describimg the o/heat cut out the thermister is just pushed into a phial pockeT a long copper sensor in two halves on the older one the new is one piece. As the boiler has not got pump over run tend to find a few that have overheated and need to be reset.
