Room thermostat not working

[swindontony]

My thermostat in the hallway isn't firing up my boiler when I turn it up, does anyone know why this should happen, it was working ok before the summer. My hot water system is working ok. I was wondering do room thermostats break down or seize up. Thanks in advance.

Does the boiler heat your hot water is it a Combi ? there could be other causes IE the pump could be stuck and there is no circulation to make the boiler fire up a good tip during the summer is every 10 days or so to run the system this is common problem at this time of year thhermostats do break down though
