Hello! I have a furnace conundrum and am looking for ideas. My 8 year old Goodman/Amana single stage gas furnace (Model GMS80904BNCC) intermittently and randomly loses its flame, then reignites. I am near Denver, CO and our temps are in the low 20s this week. The furnace is in a large laundry room in the basement of a ranch style house. It is not next to the dryer and does not have a lint issue. The thermostat is a newer Honeywell programmable. ​​​​​​ The furnace starts up normally. Tstat calls for heat, induction fan starts, hot surface ignitor glows, and the four flame jets ignite, burning strong and mostly blue. The blower motor kicks on and everything runs fine - until it doesn't. Rarely the furnace makes it through the cycle and shuts down normally once the tstat is satisfied. But usually it misfires at least once, often several times. When this happens, the flames suddenly cut out. A few seconds later, the ignitor glows in an attempt to relight. Sometimes the burners light back up on the first try. Sometimes the ignitor will glow and go dark again many times (I have counted ten) before it successfully relights. Each time it glows, you can hear a clicking sound along with the induction motor revving up. It keeps trying until it eventually relights, then limps along like this until the flames go out again or until the house finally gets warm enough for the tstat to stop calling. The blower motor never stops until the end of the cycle. It is not windy outside. There is no odor of natural gas, and the CO detectors are at zero. The furnace never locks out, and the led on the control board never shows an error code. You'd never know this is happening unless you happen to be within earshot of the furnace to hear the POOF sounds of the flame continually cutting out and reigniting. We changed the filter. We cleaned the flame sensor, and when that didn't help we replaced it. An HVAC company told us over the phone that the symptoms would make them suspect the control board. It had no visible burn marks or damage, but we replaced it anyway since it wasn't expensive. No change. The hose to the pressure switch is not clogged, and if you pull it off during the cycle, the furnace shuts off like you'd expect. Neither of the blower motors are making any unusual noise. I don't think this furnace could have condensate issues - I can't find any evidence of a drain line. Here is a video showing the issue. It happens about 15 seconds in, then again around 1:40. https://youtu.be/-H-Ihu-A_To What could be causing the flame to cut out like this? Any suggestions are much appreciated. Thank you!

Typo, This is a Coleman Furnace I have a coleman modular home heater dgaa090BDTB, Furnace keeps shutting down during high winds (1 green flash) ignition failure. I live in a high snow area and have had a roof jack extension installed and have also had the pressure switch replaced. Resetting the on/off switch lets the furnace fire back up but only for 5-10 minutes. this continues till the winds calm down after a windy storm. Any Thoughts?
