As the most common problem is that, when faulty, the temperature counts down to 18, or as sometimes reported, up to 26C - would it be too much to suspect that the switches could become faulty??
Could the switches just be sticking?
The fault is very similar to someone holding the switch down (or up).
Joe, I'll try to get you the photos of the other side of the circuit board when I get a minute or two.
I'm really pleased that there is a good focus now on this irritating problem.

Thats a very good point about sticking as you say it counts down as if stuck
