Re: flame backlash

The burners have an adjustable vent in the front that may have been moved. Also the vent pipe may be inadequate, that is why the roll out switch that you by-passed tripped. If you replace the switch that was by-passed I bet the over flaming stops,as the gas will quit overflowing. Most of these switches have a little reset button on them so look at it next time before you by-pass the wires.

Got goodman gms91155dxa got 6 flashs says rollout open

Check the roll out switch it is located right in front of the burner assembly it will have two wires on it some times they are resat-able if you have to reset it do so and then put on the heat to see if flames are coming back out to trip the roll out sensor. make sure the heat exchange and burners are clean.

How to fix a pressure switch on a goodman Gms807034ana

Since the burners light this eliminates the pressure switch as the problem. Typically when the burners come on and shut off quickly a flame sensor, ground problem or the limit switch tripping are the main reasons. Since the flame sensor has been replaced, check the limit switch

I have a goodman model gms80703ana the burner comes on and when the blower comes on the burner goes out.

This can be due to a dirty flame sensor or a high limit switch tripping. Clean the flame sensor first, this is a metal rod on the opposite side of the igniter, take steel wool and scrub it, then reinstall. If this does not work then the limit switch is tripping due to dirty filter, dirty blower wheel, weak blower motor. Aything that restricts airflow will cause the limit switch to trip.

Unfortunately that means there's a hole in the heat exchanger, particularly in that cell of it. When the main blower comes on the air is pushed into the heat exchanger, causing the flame rollout. A heat exchanger crack or blowout is usually what condemns a furnace for good. Goodmans however, have a lifetime warranty on their heat exchangers, so you'll probably be able to find someone to replace it pretty cheap, or do it yourself for free.

My circuirt board has a rapid flashigh trouble light, and the blower does not shut off. What seems to be the problem?

with just the information you have provided, i would guess you have a rollout sensor somewhere that has been tripped. there are usually a push button reset on the goodman models. this usually happens when you have flame outside the heat exchanger and is not a good thing. i have seen some goodmans where the wiring for the safety sensors is melted from the flame rolling out due to a crack in the heat exchanger. it this is the case, you need to replace the heat exchanger or consider getting a new furnace. the safety wiring on most goodmans is usually purple. trace all the purlple wiring and see if some of it is melted or if any of the push button switches has tripped. on a high efficiency model, there will be several wires and rollout switches located along the top of the burner box above the burners.
good luck. by the way, anytime a safety has been tripped, the fan will default to the on postion as a precaution in case the furnace has got too hot. that may explain the fan running all the time.

What does it mean when my goodman furnace is flashing a red light and will not work.

It is in Lockout mode. Something has happened to make it go into lockout.
It could be an easy fix. Look of cobwebs in the tubing between the proving switch and the draft inducer motor. Look for air restrictions in the chimney flue. Rusty burners (if applicable). Tripped rollout switches. Some times there could be up to 2 roll out switches on the burner and another in the flue and 2 others in between stuff. . Most times it is a dirty flame sensor. Over the summer the flame sensor gets dusty and the sensitivity gets off. The control fails to FEEL the probe and locks out the gas valve. Most times the failure will be defines by the amount of blinks the red light emits. The sub panel has a guide on it that tells what the blinks mean.

Hello Try looking for a tiny TAN colored (button) near the front of the burner rack.It will have a wire in & out of it.In the middle there is a small tab/button.Push that in you will hear a click.That is the rollout switch.Check the vent/exaust pipe for blockage/draft to determine the cause of the switch tripping.The switch is a SAFTEY and repeated trips means there is a problem.

Preblower comes on, Ignitor lights up, but no flames. Control board blinks 6 times, indicating Open Rollout. What does this mean and what are the recommended fixes?

Roll out flames are a safety device on a furnace. On the furnace back up under where your burners are located, you will see a switch with a manual reset button on it. What is happening is the flames have rolled out further than they should have at one point during its cycle, and tripped this switch to keep the flames from burning the wiring and what ever it might reach.It is one of many safety's on you're furnace.Reset this switch, like I said, it would be where the flames would come out a little to far. Sometimes they will trip if you get a gust of wind down the flue pipe from the roof. Or, if the burners are getting plugged up with black soot.Check this also.Until the switch is reset, the burners will not come on. You should have no problem finding it, mounted just at the end and above the burners. Walk out side and make sure your flew cap is in place. I have found birds nesting in flew pipes that will cause this.Reset it and watch it for awhile to see how it burns.Don't worry, as that is why the switch is there, for you're safety. I am sorry for such a long solution, but it is called for on this problem. Please let me know how it turns out.
Sincerely, Shastalaker7

Goodman modle gmp100-3revb heater ignites and then shuts off.

If you are getting ignition but it does not stay on long, check for a bad ground off of the circuit board to the chassis cabinet. Look at the flame sensor and the connection on the circuit board. Is the plug making contact to the board or is there a bent tab? Is the flame spreading from one side of the burners to the others very quickly or slow? If quickly, it has to be either the sensor or the control board. If slowly, clean the burners and the flame spreader.
