Fixing a stuck microswitch in a 2-port zone value, which was causing my boiler to fire erratically!
In this video I investigate the cause of what I initially feared was a gas leak, but what turned out to be a stuck microswitch within a 2-port zone value.
After an emergency visit from Cadent confirmed there was no leak, I set about investigating why my boiler was using gas, despite the thermostat being off.
Follow along as I trace the source of the problem, eventually discovering the fault was the microswitch inside my Under Floor Heating Two Port Zone valve. Thankfully I was able to get the switch working again (some dirt perhaps?) and my issue is resolved!
