I have an old gas burner and a digital thermostat. On some mornings it does not come on when heat is called for. I manipulate the thermostat, thinking it may be faulting. I have it set to come on at 4:30am with the temp set for 72. When Its not coming on as it should, the temp of the house says 68. I lower the set temp just below 68 and i hear the click on the thermostat, then i raise it again to 72 and i hear the click again and the heat comes on. I cannot afford to replace this boiler just for that reason. Does anyone know what causes this and how to rectify it, other than buying a new boiler? and possibly the cost. Maybe it needs a new pilot switch? BTW, when its not running with this problem, I do hear a constant running in the background...sounds like a burner running, but there is no flames .
