Ravenheat Ravenheat LTS80 Heating, Home Heating Systems Ravenheat Boiler Hot Water

The small temperature thermocouple which has a geen plug on it with two yellow wires has failed or has been tightened up too much because it may have been leaking. It has a fibre washer on it which is crap, and when it is tightened up too much it twists the internall parts so it cant latch properly. Everything works on the boiler but it just wont ignite, its a bugger.

Your over heat stat has failed. Its the one attached to the copper pipe on the left hand side on a little square plate.
