Lennox pilot will not stay lit
Yesterday the pilot went out on my Lennox furnace. I lit pilot and the burners came on. The unit worked until the thermostat reached the temperature I preset(about 20 min.). The furnace turned off (cycled) and the pilot went out. After lighting the pilot several times with the same results I went out and bought a thermocouple and installed it but set the thermostat at a higher temperature the furnance ran for about an hour or so and the pilot went out again. The pilot flame is mostly blue but periodically I see flashes of yellow. What shall I check next?
