About 4 weeks ago my nest stopped being able to turn on or off the central heating on my glow worm 38cxi.
As the boiler looked otherwise fine I figured it was the nest heatlink itself which has been working fine for 3 years. I managed to organise a replacement heatlink from Google but on replacing it I'm having exactly the same issue with the new nest.
No errors are shown on either the boiler or nest. If I press the manual heatlink button it does click like it's turning on the heating but the boiler doesn't respond. If I want heating I have to manually press the heating button on the boiler itself.
I've done a continuity test from the heatlink to where the wires connect into the Glow Worms PCB board and that is fine. Beyond that though I don't have the expertise or knowledge to know if the PCB itself is faulty. I've checked for cracks/corrosion etc and it looks fine.
Is it a matter of simply replacing the pcb at this point? Seems like an odd thing to just stop working without any other symptoms of issues.
Thanks
