Goodman gas furnace model number gms80904bna won't light. Changed the flame sensor and the ignitor is bright orange please help
Obvious that the unit isn't getting gas to the ignitor.
To receive gas to the ignitor, there is a gas valve located upstream of the burners.
Have a friend turn on the heat while you are up close to the furnace.
Once the ignitor gets hot, there will be an audible "click" at the gas valve when the low voltage controls call for the gas valve to open to supply gas to the burners.
Listen for it.
If you hear a click, and the furnace still isn't firing, you need to check to see if someone has closed the gas shut off supply valves located on the gas line.
If all the shut off valves are open, you need to verify you have gas pressure in front of the gas regulator.
If you verify have pressure on the upstream side of the regulator, you will need to verify there is also pressure downstream of the regulator.
If there is gas pressure upstream but none downstream, replace the regulator.
If you have pressure downstream of the regulator, and the gas valve clicks, but furnace doesn't light, replace the gas valve.
LP has higher pressure than natural gas, and is dangerous.
LP is heavier than air and will sink to the floor or lowest area.
One static electricity spark is all it takes and an explosion can occur.
GMS80903BNA goodman furnace. Short cycling
I have the same problem. The vent flu. Is building up condensation and running back into the furnace and cloggs the little black vent hose with water. Then it comes back on then off etc.
somehow the trick is to make as straight of an upward vent flu as possible ( definitely not 45 degree elbows and really not 60's either) seal all connections with glue.
