Re: Goodman Gaspack

It is suppose to terminate.the deal though is when your ignitor, the heat from the burner flame will make it appear as though it is on.

do this.turn your gas valve knob off and turn the heater back on.observe the burner compartment.first you'll hear the flue inducer start.then your heat ignitor will glow.then you'll hear a click.that is your valve trying to open.then your ignitor will stop glowing.

The glow stick lights up; approx30 seconds later, you can hear and smell the gas turn on, but the flame does not start

Depending on the specific unit you have the hot surface igniter (glow stick) may be only for lighting the pilot, which then ignite the main burners. The flame has to be proved before the gas valve opens for the main burners. This is done by the flame rod, which could be faulty in your case. The proximity of the igniter could also prevent ignition. Check that the flame rod is clean and secure. Note. be very careful when servicing gas appliances, and never ever use lighters, matches or any other flame source to light them except for the ignition system supplied by the appliance. These appliances are designed and built with safety devices to prevent ignition when it senses a fault or malfunction. This is all for safety. Do not bypass safety devices, it can kill. Call a qualified tech.

Why heater coils glow?

It sounds like you're describing one of two things. The hot surface ignitor in a gas-fired furnace, or the resistive heat strips in an electric furnace.

The hot surface ignitor in a gas-fired furnace lights the burners. This ignitor in modern furnaces serves the same purpose as the standing pilot flame did in older furnaces. It provides the required heat to ignite the gas at the burners. Without an ignition source, a gas-fired furnace cannot provide heat. When the ignitor is activated it will glow bright orange or yellow.

The resistive heat strips in an electric furnace actually provide the heat to a home or building. When the furnace turns on, the heat strips are activated and usually glow orange when they reach peak temperature. In almost all cases, the heat strips are not easily seen or accessed without removing covers or panels inside the furnace.

Goodman gms80903bna light blinks once fan runs all the time,

I believe this code is ignition failure.
Turn power off and after 20 seconds turn power on with thermostat calling for heat. Vent blower should come on first. After a bit igniter should lite up. You should hear click noise of gas valve open up. If igniter does lite and you hear click noise, flame should come on for a few seconds minimum. If igniter doesn't lite and you hear click noise from gas valve, igniter is bad. If flame lites and then goes out, flame sensor probably needs cleaned. Both igniter and flame sensor are in metal plate under burners. Igniter has 2 wire going to it and flame sensor has one wire. If you think it is flame sensor you can remove with taking it out with 1 1/4" hex screw. Flame sensor will have white film on it if it needs cleaned, clean with steel wool or a dollar bill. If it isn't weither of these it is gas valve or circuit board.

Ten yr old Goodman residential furnace won't light even though hot surface ignitor glows red for 1 or 2 seconds.

Make sure you have gas on. Tap on the valve as the ignitor glows. The valve may just be stuck. If not- I'm thinking the funace needs a new ignition module.

I have a Rudd furnace model UGRA-04EMAES in heating cycle inducer makes pressure switch ignitor lites up no gas pressure i rplaced gas valve and board still no gas. Wat next?

Well first you want to verify that there is gas pressure coming from the connector. Turn off the valve and disconnect the connector. Then turn on the valve for 1 second and back off. You should get plenty of gas flow. Be careful doing this!. Then inspect the opening at the adapter to the control. There is a screen inside there. Make sure the screen is clear(not plugged with pipe dope,lint ect). When the igniter reaches the 2200 degrees you should hear the gas solenoid valve click open releasing gas. If you hear it click and no gas is released you will need to inspect the burner orfices. The orfice has an extremely small hole and there is a posibillity that they are plugged with debris. You will need to use a very small wire(like a tie strap) and insert it into each hole and see if there is anything in the orfice. If you do not hear the gas valve click then it might not be getting the signal it needs due to a weak igniter or flame rectification sensor. Does your furnace have a stand-by pilot that is lit by the hot surface igniter or does the igniter directly light the burner assembly?

Goodman unit. when i turn it on the blower fan and the exhaust fan comes on butit does not lite no flames at all. i don't even hear the gas click in.

On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).

The exhaust blower starts for about 15 seconds then shuts off. several minutes later, the same thing happens - over and over

goodman furnance the exhaust fan starts, igniter glows hot, all burners lite up & will burn for about a minute and shuts down . I think it senses the room blower does not start so it shuts down.
