Question about Goodman GDS80904BNA Open Flame Heater

1 Answer

Flame Adjustment Recently installed furnace and Amana AC. When furnace ignites it is very loud and sounds like a blow torch. The manual states the flame should be soft and blue. I have asked the company that installed the unit and they say the flame cannot be this right. This unit is located in a furnace room (vented) in our kitchen. Without an adjustment I find the noise of this unit unacceptable.

Re: Flame Adjustment

Make sure the unit is operating on the correct gas, Natural or Propane (LP). The sound you are experiencing is either not enough gas and the flame is burning inside the burner port(s) or too much gas and the flame is much larger than it has to be. At any rate, get a technician to check the gas pressure entering into the home. NOW!

Where should the flame blow when janitrol furnace is ignite?Toward firewall?

It sounds like he incorrectly installed the igniter and it may be a huge danger to your home. A incorrectly installed igniter can cause a excess build up of gas and blow back flame or worst blow up your house. Only have a licensed heating and cooling contractor work on your furnace and not a handy man.

Coleman furnace problems

I take you mean there is a fan coming on that blows AC air thru the vents and is the same fan used to blow the heat ? If that is the case is the fan coming on when the heat comes on ? If not then that is why you are not getting the heat.
That can be from a temp sensor not working or a control board or a contactor
First see if the fan even comes on or if the same fan is used for both AC and heat

The Goodman Heater was installed in 2004. Thermostat set at 75F, the fan that blows CO2 out was on for about 1 minute, then I could hear the sound of the gas blowing into the furnace, but the ignitor...

Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:

1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution:You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

Amana Air Command 80 SSE gas furnace will not stay running

In the path of the flame on the last burner that starts, there will be a small rod. That rod is the flame sensor. Take a scrub pad and polish it. Also check the electrical connection that goes back to the circuit board. Disconnect any ground wire from the circuit board to furnace cabinet, sand it and replace it.

I have a coleman furnace with a pilot light that keeps going out.When i manually light it the furnace runs 12 to 14 hours, then no more pilot light and i must relight.

Remove the burner and gas valve from the furnace and use compressed air to blow the area under the pilot area ans all around it. The dust and stuff usually cause a condition called "Lazy Pilot" and the flame is probably not going in the designed directions. While you have it out Id replace the thermocouple with a new one reassemble and re-lite and note the difference. The flame should be mostly Blue and no yellow (or vary little at the top end of the flame only) Orange in the top area indicates a good burning flame and the closer to the base the bluer it gets.

While you have the burner out look inside and inspect the inner heat exchanger for cracks or rusted open holes there should be none. Turn on your fan while inspecting and see if you feel the steady blow of air from it inside the heat exchanger indicating a hole. Don't confuse the air that may come down the flue with the air from the blower though. A little breeze is expected from this.

This will take care of over 90% of the problems with the "Blow out" symptom.

If you still have problems you can try and "turn up the pilot". Usually a screw close to the pilot tubing is covering the adjustment screw. Put some soap bubbles around it so you can see if it leaks or not and turn the screw out for more flame (CCW) and in (CW) for less.

Hope this helps Please grade me accordingly and good luck.

Furance will not stay running


Check your manual for your t-stat to be sure that it is set to your type of heating system, this is usually the cause. In the manual for the t-stat, it has settings for your type of system. You state furnace, that means it blows warm air, a boiler circulates hot water. This is most likely the cause of your heating system not operating.

I am assuming that this is a gas system. It sounds as if you are getting ignition, which is good, but not any fuel. I ask that if you are not familiar with gas systems to call a professional, but you can hear if the gas valve opens by starting it up and if you hear a series of clicks and the sound of air coming through, then the valve is opening. It can be a number of things and you will need a multimeter to check the operation of all the connections and relays.

Hope this helps.
