Hi I have GMP075-3 model of a Goodman gas furnace. The heater would make the sounds that it was beginning to work. I could see the ignitor light but then nothing else would happen. The repair guy came and said the Burner roll-out limit was somehow tripped the other day. Possibly from a down draft from the chimney. When he was here it lighted and blew several times after he reset the limit. It ran well that day. The next day, it was much warmer outside so I turned the unit off. Now I have the same problem.
Can I reset the limit myself? Where is it located? What would it look like? What do I need to do?
I would rather try to reset it myself so that if I need to call for a repair I can give more diagnostic information... how long it was running for... what temp I had the thermostat set for.

If anyone can advise me on anything in this situation, I would be grateful.

You could try killing power to the whole unit. If that doesn't work, I hope Northern heat drops in with a better answer soon.

Goodman/Janitrol GMP model huh. Get a qualified service tech to check the rivets in the heat exchanger. If the furnace is more than 6 years old they are probably all broken. Pieces of junk I don't know how they didn't get sued out of business.

But that's just my opinion. Besides I really do like them, it means a lot of sales.

There is a block in the heat exchanger or the burners are bad you shouldn't us the furnace until it is fixed you may have a bad heat exhanger

This was from Oct 22 2006. I think it has probably been fixed

The threads are never closed so as people search this board they find a post that is similar as theirs and post to that thread. LOL This is happening a lot lately.
