We have this problem happen before when the power went out it trips the limits so it doesn t burn up the blower.
One of the most common culprits of a furnace that is having a difficult time lighting is a low gas supply.
This means that the blower is not working or the pressure switch circuit has a short in it.
Turn the furnace off and leave the house.
It is typically located either beside or behind your furnace if you are having a difficult time finding it.
Find the gas supply valve next to or behind the furnace and rotate the valve to the open position typically by twisting counterclockwise.
You can solve this by cutting power to your goodman furnace for 30 seconds or by lowering your thermostat to what it was before you turned it up and then try to turn it up again.
Stop immediately if you smell gas.
One setup that commonly creates this condition is use of the blower fan.
Your furnace will automatically try again after an hour of lockout.
The goodman furnace may not be receiving an adequate gas supply if the glow ignitor turns on but the furnace cannot ignite.
If you have your fan set to on at the thermostat instead of being set to auto this will cause the furnace to not ignite when called upon.
