I looked through all of your recent posts and uploads hoping to find a manual for a Coleman furnace FG8B05012MU11A. Having a problem with an over temp sensor shutting the flame off after a few minutes and not restarting, the indoor blower continues to run while in a fault condition. This is 4 flashes. If I reset the power it resets the board and fires back up but does the same thing after a few minutes. I see several sensors on both sides of the gas nozzles.Thanks in advance
