Hello my name is Heath it will be by pleasure to assist you. Check the burners themselves. Also it may be the gas pressure is to high or the regulator isn't set right. Have someone check the gas pressure at the unit before and during ignition.

Rollout switch open displays

Fusible link or the Roll out switch are one and the same...
if it burns out, or provides 'Open Circuit', then you had heat or flame exit the front of the heater instead of up!
This is a problem that needs correction.
Most common reason, Sooted Heat Exchanger / Tube Bundle.
dissassemble and clean it - not with a brush!!!
2nd possibility, especially if outdoor installation is a 'Downdraft'.
Don't just replace rollout switch - FIX the reason it burned out!

What is the cause of rold out flames on gmpn 120-5 furnace

There can be many causes of this. First check to be sure you are using the correct gas type (natural gas or propane) for the heater. It may need to be converted to the correct gas type.Then check to make sure your venting is not blocked (bird nest, etc). Sometimes it's a soot build-up inside the chamber and flue, which can be caused over time due to one of the above problems I mentioned.

Can you run your heater without a roll out switch?

The roll out switch is a safety switch. It is there for safety. The purpose of the switch is to cut the gas off if there is flame or excessive heat low in the heater as found when the heat cant exscape out the top. Many reasons for a roll out failure if you are tripping the roll out it is always a symptom of a larger problem.
Low gas pressure or lack of combustable air causes soot in the heater like that of a chimney. This will restrict the air flow through the heater. A spider web in the gas oriface or burner can cause a roll out flame to hit the roll out fuse. Indoor applications can easily be an issue with the exaust venting or fresh air supply. Outdoor applications it could be a wind down draft through the heater. Whatever the reason it is tripping the roll out fuse, by bypassing it you are allowing the gas and burn to continue in an unsafe condition which mean larger problems will arise possibly even the heater catching fire.

Installed new heater it ran for 15 minutes and the gas cut off. The combustion fan and the fan keeps running, the only way to stop them from running is to throw the breaker. LED light blinks 4 times, book...

the high limit is an over heat switch that could mean the unit is over fired. you would need to time input or check manifold pressure. the roll out switch is a switch that shuts the unit off if combustion is spilling at the divitor on the unit where the vent connects. with this you need to check your venting

I have a 2004 jeep wrangler that wont accept fuel corectly it shuts the pump off no matter how slow i fuel it

there are two valves on top your fuel tank,
one is a roll over valve that will close off the fuel if the vehicle rolls over,the other is a vent valve that lets pressure escape while your filling it with gas,this valve is not letting the air that is going in the tank with the fuel vent out ,so it is coming out the only hole it has which is the filler tube.

My heater works fine when its a little cold,when its freezing outside it heats for a couple of airs then it would come on and off fine but with cold air blowing.i looked at the codes it blinks 6 times...

do not adjust your gas pressure without an manometer or if you dont know what you are doing could be very dangerous. Roll out switches are manual reset if you have an open roll out on a Goodman furnace you probably have a cracked heatexchanger, get a qualified technician out there asap
