    Goodman furnace problem
    I have two goodman furnaces. They both heat up, but, they both have erratic or uneven sounding flames. They run for a while and then click the flame sensor snap switches off. What would cause this, especially same problem on 2 different units?

    Also if you can see, make sure the little orifices that shoot the gas out aren't clogged. Over time they may be partially clogged and cause uneven gas flow. Try and clear them out with like a toothpick or something. Check where the flame comes out of too to see if anything has built up.

    Also if they're both run off the same main gas line, maybe there's air in the gas line or some inconsistencies that the city put in there on accident.
