Mend Ravenheat LS 80- 80 T Heating Boiler Thermostat

How can I fix my boiler, ravenheat silver star LS 80- LS 80 T?

The boiler has a room thermostat connected to it but when you set the room thermostat to the temperature needed. After a while the thermostat switches off but it does not come back on when the temperature off the room drops. The thermostat has been checked and is working. Therefore we assume it is something wrong with the boiler. Can you help!!!!!!

the mains powers up the thermostat
the thermostat powers up heating valve
Heating valve powers up the boiler to heat the room


If Thermostat OK and powering up heating valve
Heating valve not OK and is not powering up Boiler.(Possibly stuck microswitch)

(same applies to combi boilers with integral three port valve)
