Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

If this is a HSI (hot surface ignitor) it's a control error if it doesn't stop glowing once the main burner is lit. Keep in mind that part of the igniter is in the burner flame. That part will still glow after the burner is lit because it's hot from the flame. This is normal

Expert:  Rick replied 8 months ago.

You have to replace the control device. Since I don't know what that is I can't be specific without know what type of unt this is. In most cases on warm air furnaces it's the control board.

I had thought that that might need replacing, so I did, I have a Trane XE90, I replaced the old control board with a White rogers 50a55-843, universal control board, however, after doing so, the ignitor did not go on at all, so I put the old control board back in and now i'm stuck with the original problem
