Recently the gas company replaced our meter and thermocouple. After they left, the pilot light kept going out randomly. 4 techs came over a 3 day period and could not diagnose except to reassure that the meter and thermocouple were working fine. Then HVAC man came and found lose wires on the gas control valve, apparently knocked lose by the gas co tech. Furnace will cycle perfectly and pilot stays on as long as the thermostat temp is maintained at the same temp, but whenever I bump the temp up a couple of degrees, the pilot goes out either during the cycle or upon shut off.
