Dear Mr Jones

I have a D2 with Digital Timer Modulator (unfortunately without diagnostics), fitted to my boat, which is failing to start. Symptoms as follows- at switch on fan runs slow for 1 minute, then speeds up a bit for another minute at which point fan very briefly surges then reverts to slow speed for a further 5 minutes before completely shutting down. The pump does not click.

In trying to diagnose the problem I have checked that the supply voltage is ok, I can get the pump to click by putting power directly across its terminals, the glow pin and flame sensor resistance readings are good. However the overheat sensor (between blue and brown/white wires) gives an open circuit not 60k ohms as it should.

Hence it seems that the overheat sensor is faulty, but before I purchase a new one I would like to know please if failure of the overheat sensor would give rise to the symptoms I've described. Hope you can help.
