my furnace intermittenly cuts off. The first few times it will restart after one attempt. With-in a few weeks it will start cutting off almost constantly soon after I initially turn it on. It will also attempt to restart 3x without succsess then shut down completly. The restarts always have 3 clicks #1 is okay #2 (air vents or blower) is okay, #3 the gas/igniting is what fails. Heating man #1 changed a relay switch,that did not work. Heating man #2 just looked at me like I was stupid because it worked fine while he was here. (so I shot him). Gas guy said it is receiving enough fuel. Then summer came, thank god. Please, I need advise before it gets cold.
