Are you having to manually reset the limits or does it auto reset?
Can you give me complete model from inside furnace in burner compartment so I can provide guidance with this specific unit.Model will be on a label just above burners on right or left inside panel
Ok what is model on unit and are these the ones right beside or above burners (flame roll outs? If so is the flame coming out of the heat chamber to trip them when blower comes on?
OK first thing is to watch the burners and see if the flame is floating out of the heat exchanger causing the rollout limits to trip.If it is, the problem is much more serious than just limits.You have a bad heat exchanger.
If we can determine flame is fine then you will need to replace limits.If the limits are so close to sides that you can not get to them, we should be able to remove the burner assembly from the furnace by taking a few screws loose.
I will need model on unit to give you specific detailed instructions on removing .
I will need the model to pull a manual to identify the exact location of the switches and give you detailed instructions.Nothing on te Goodman furnace should require removing the furnace or cutting any holes.
Do you have internet access on site when you get there?
Sorry I got called out of the office.Did you get the model number?
