Problem: I purchased a flame sensor from you for my Goodman furnace. The new flame sensor did not fix the problem. My furnace still lights for 7 to 10 seconds and then the gas goes out. What could be the problem?
Answer: Since your furnace is still having what sounds like flame sensing problems I would suggest making sure the flame sensor is positioned in the flame where it is getting a good hot blue flame to sense. I would suggest checking all connections to make sure they are tight (especially the ground connection on the transformer). Check your plug-in connection that goes between the blower section and burner section of your furnace. Check wire and flame sensor connections to make sure they are tight. I would recommend checking all rollout switches, limit switch and pressure switch to make sure they are closed (current flowing through) them all the time. This could be a control board problem, not sensing the flame. I you have any other questions please email us anytime.
