SOURCE: Empire DV-215 Low Flame Issue

Either a restriction in the gas train, low gas pressure or a bad gas valve. Check the pressure on the gas line when on pilot and again when the burners are running. Depending upon what type of gas it runs on, you should have at least 4" W.C. if Natural Gas and 10" W.C. if Propane. If gas pressures test good and all valves are open, you are looking at replacing the gas valve.

SOURCE: low flame signal

There is a small probe that is located inside the firebox and the flame from the burners will touch it. Typically it is located to either the far left or far right of the fire box if it is a vertical furnace. if the flame is not touching it or if it is taking the flame too long to travel across the burners (right to left or left to right) you will get this error code. Find the sensor and clean it with a small wire brush. Make sure what you think is the flame sensor is the flame sensor because the ignitor is very brittle and has two wires going to it. The flame sensor will have only one wire going to it. Also since you have the burner compartment open, inspect the flame spreader tray for blockage not allowing the flame to spread quickly. A can of air and the small wire brush will aide you in this cleaning.

Good luck to you!

Burner lights and shuts off 3 times and then give warning lights A and B


It depends on the model but AB on most of the AOS the A & B LED's lighting up usually means ignition/flame failure.

Ignition/flame failure:

The gas control valve/thermostat has reached the maximum number of retries (3) for ignition and is currently locked out for one hour. Cycle the power to the water heater off and on to reset.

Basic troubleshooting/solutions:

1 Ensure flame sensor is making good contact with the burner flame and ensure flame is steady. Also ensure supply and manifold gas pressures are within the requirements in the installation manual.

2 Gas supply is turned off - pressure is too low. For low gas pressure, consult with your gas utility.

3 Ensure the flame sensor is clean - use fine steel wool to clean the flame sensor.

4 Check igniter assembly plug and the socket on the bottom of the gas control valve/thermostat for good connection. Replace igniter assembly if the plug is worn or damaged. Replace the gas control valve/thermostat if socket is worn or damaged.

5 Replace igniter assembly.

If this does not apply to your model then here is a link to the instruction manuals for all models:

I have goodman GMP series furance the furnance and gas comes on and fires up then goes out flame sensor is good what else could be wrong


Improper ground from control to burner.
Incorrect electrical wiring, check polarity.
Tubing partially clogged between inducer and proving switch.

A sampling of various failure codes on a furnace:

Read one LED flash that stays on continuously to mean your furnace has no signal coming from the thermostat and will not operate. Turn the power off and check the thermostat for improper settings or connections.

Interpret one LED flash that blinks on and off to mean your furnace has locked out because it could not ignite after three tries, and must be reset. Interrupt power to your furnace for 20 seconds or lower the thermostat so your furnace does not try to heat, then reset the thermostat to the previous setting. After one hour of lockout, your furnace will automatically reset itself and try to operate as usual.

Decipher two LED flashes to mean the draft blower is not working, or your furnace has a short in the pressure switch circuit. Turn off the furnace power and repair a short or replace the pressure switch.


Read three LED flashes to mean your furnace has an open pressure switch circuit or it has an induced draft blower operating. Check the pressure switch hose of your furnace for blocks or an improper connection. Also, look for blockages in the flue, and tighten any loose wiring.

Translate four LED flashes to mean your furnace has a primary limit circuit open, possibly from loose wiring or blocked filters. Check and clean filters, tighten wiring and check the flue for blockages.

Interpret five LED flashes to mean your furnace senses a flame without a call for heat. This could be from a gas valve closing slowly or a burner flame lingering.



Read seven LED flashes as a warning of a low flame sense microamp signal. This could happen with a coated flame sensor or a lazy flame from poor gas pressure. Turn off the power and adjust the gas pressure according to the information on the rating plate.



See eight LED flashes as meaning an igniter circuit problem due to a bad igniter or an igniter connected improperly. Replace the bad igniter or check the ground wiring, making necessary corrections.



Decipher nine LED flashes to mean the high-stage pressure switch circuit will not close during a high-stage-induced draft blower operation. Your furnace may have a pinched or blocked pressure switch hose, a blocked flue or loose wiring.

Read continuous flashing on the LED to mean your furnace has a reversed polarity of 115 volts. Turn off the power and correct the wiring polarity after reviewing the wiring diagram.

The flames from the front left burner is 1/3 orange and 2/3 blue; whereas the flames from the other burners are all blue. There is a strong odour from the front left burner when we turn it on and also the...


The flames should be all blue - except when you first turn it on, where the flame begins, & only when you turn it on. Orange flames mean incomplete combustion is happening. Carbon monoxide is being released. Orange flames can also mean your getting low on gas. Clean it & try moving the disk around. An uneven disc means some flames will be higher & burn your pots. The flames are wrapping around your pots if they're burning on the sides. Keep flames under the pot. Regardless of the being clean, the odor means you need to check your gas level. Once filled back, the odor should be gone if that's the only problem. That is placed in the gas as a safety feature. Don't try to fix this problem yourself if the "easy" solutions don't work. It could be very dangerous. Invest in a carbon monoxide detector especially when you have anything gas.

The dryer is not heating up. Just blowing air. What do I do?


Gas dryers CLICK when the glowbar warms up the flame sensor to the point that the bimetal inside it bends. This insures the flame is lit. The flames stays on just long enough to warm the drum up to 160f. (for cotton) at which time the flame is shut down until the temp inside the drum drops to 105f when another blast of heat is applied by the control thermostat. If you hear the clicking then the ignitor is glowing AND the flame sensor is shutting it down. That means the thermal limit and control t-stat mounted on the blower housing is working. If that is the case then the coils are bad. Replace them.

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.

I have a model LDG712 gas dryer. The flame ignites and burns for about 20 seconds. The flame then stops burning and it about 1 minute and 30 seconds or more before it lights again. The glow bar...


The flame should cycle on for about 50 seconds on the first cycle and approx 20 sec each additional cycle. I would check your airflow out of the dryer it my be restricted not allowing the flame to pull through the burner tube causing the unit to "short cycle". Its not likely a thermostat issue but if you were to replace a thermostat I would replace the cycling thermostat should be part number 3387134. Hope this helps.

My temp keeps droping and there is a little flame indicator underneath the current temp. No matter what i do the little flame indicator doesnt go away. What does this mean? And why cant I get any heat?


The little flame means that your thermostat is in heat mode, that being said make sure that you also set the blower to auto. Should this not get you heat remove the thermostat there will be a red and white wire on the back of the thermostat remove them then touch the two together or twist them together. What this does is runs the furnace with out the thermostat, should the furnace come on you have just proven that the thermostat is bad. Now your job is to replace it and please take your time, pay attention to what wires go where.

I have a White-Rodgers Thermostat and it has the word (Filter) on the left side and a (Flame) showing on the right hand side, I'm not sure why we changed the filter two months ago. Does anyone know what...


Flame Icon is displayed when the SYSTEM switch is in HEAT position. Display "FLTR" when the system has run for the programmed filter time period as a reminder to change or clean your filter.
You can reset the counter by going inside the configuration table of the thermostat. If you need further clarification call our WR hometechline 18002842925.
