[HVAC] Furnaces sometimes tries to igniteI have an older gas furnace. It has no blockage on roof or by filter. I have cleaned igniter, as well as rest of the furnace. You can hear and see it click and try to ignite. Sometimes it will sometimes it won't. Any ideas? |

It could be the pilot orifice itself is partially blocked, this can come from an accumulation of impurities in the gas getting stuck in the tiny orifice.
Be careful cleaning it, you don't want to damage or enlarge the opening. |

Could be a bad or weak transformer or it could be the gas valve isn't opening. |
