The thermostat in the door is a thermistor and is behaving correctly.

Hi there and thanks for getting back to me, sorry, I was not very clear about the action of the main thermostat, it is actually reading Zero ohms i.e. Short cct. I did suspect that the door ‘stat was a thermistor but wanted confirmation before buying another.
Looks like it may be the programmer then??
