If furnace is turning on and off, there may be a control board in blower compartment with a light that flashes a certain number of blinks to tell us where to start .Can you check this?

Customer: replied 1 year ago.
will do.
Expert:  airheatman replied 1 year ago.

Let me know and we will go from here. Here is the flash code chart. The number of blinks between pausing will let us know where to start.

I am having a prob getting in there... But I just noticed for the first time. When the furnace goes on, the flame lights up for about 2 or 3 seconds and then shuts off, but the furnace keeps running for about 3 minutes.

Lets start by looking in front of burners for a flam senser rod and clean it.
