Sounds like the furnace is tripping off on a limit safety, either temperature or air switch. Check filters and restrictions to air flow (furniture over return air grills, blocked filters) also, check the drainage line of the system. If the furnace can't drain water fast enough it will back up internally, and trip the system off on a pressure switch safety.

hope this helps.

SOURCE: Goodman heating system

It really depends on the type of system you have. You will either have a furnace, high efficiency furnace, heat pump system, heat pump with gas or electric back up heat. All these systems operate differently and the problem that you are having could be caused by multiple issues, depending on which system it is. More info will be greatly appreciated. Make sure to check all filters and air flow first before going any further. The system could be over heating and tripping a limit, causing the system to stop producing heat until the unit has cooled back down.

Attic Insulation and Energy Costs


This short Testimonial is meant to help you save money on your energy costs as I tell you the horror story that I recently went through..

My brother in law recently bought a 2900 square foot house with huge vaulted ceilings and a large Atrium. We started doing rennovations to the house and Mike comes to me and asks me to check out his 2 furnaces. I asked him why, and he explained to me that the 1st 13 days of work we had done cost him $270.00 to heat the house and when he contacted our local gas company, they told him that the winter months cost the previous owners over $600.00/ month. Mike was ready to sell the house. I checked out the furnaces and they were functioning fine. I decided to go into the attic and look to see how much insulation was in the ceiling. What I saw next is something I have never seen in my 20 plus years building houses. There was zero insulation up there. It took many days to roll and blow insulation in the ceiling but first full months gas bill was under $400.00. His case was extreme but it cut a third of his energy costs. Insulation is something that you can do to your home that will start saving you money from the day you put it in, no matter what the season. I also recommend that people install humidifiers into their heating systems and keep them set at 40-45. By adding humidity to the home, you can keep the thermostat turned down and be just as comfortable while saving @ 5% of your energy costs for the month. Good Luck and save that hard earned money.

I have a downdraft Goodman furnace. On only some occasions the blower will start, then after a few seconds I will see the igniter light up, but then I do not get the rush of gas and lighting of the...


It sounds like you got a tough one there.When you say the blower starts up and then the igniter comes on are you refering to induced draft motor or main blower. The proper sequence is for the thermostat to call for heat at which point the induced draft motor should come on and run for 30-45 seconds,then the igniter should heat up for a few seconds then gas valve should open and main burner should light. After limit switch reaches set point for fan on ,blower should come on till after heat has reached thermostat setting then burner should go out, and blower run until fan off setting is reached on limit switch. If your furnace is not following this sequence and then not always doing the same thing in the same order,I would recommend that you change out board again. I have had several problems similar to this with Goodman units and all but one time installing new board solved it. That time I did everything I knew to do and talked to factory service techs repeatedly and finally installed new furnace. As far as your question about insulation,. As long as it is fire proof I can't see where it would hurt anything. Sorry I'm not more help. Good luck and thanks.

Goodman furnace was installed on its back- Problem?


The furnace can not be installed with the doors facing up. It will not work properly and yes it is dangerous. The unit needs to be flipped to its side, and the plenums and the ducts need to be changed around along with your Flue (vent) pipe, and gas line. HVAC-R Tech

Goodman GMP125-5 furnace burners won't fire


Try to bypass the connection of the pressure switch to confirm if the pressure switch is really bad, and reset the unit. Monitor your pressure to be sure that its normal and not the cause of tripping your pressure switch.
