Lock-Out happens when the unit tries to start and fails after three consecutive attempts. Usually it's the flame sensor or the igniter. Its best to be in front of the unit while it attempts to start to see which component is not working. It will be in this order- The induction motor comes on, then the igniter which will be the glow you see, then the gas valve opens and flames start. If the flames never start, the igniter is bad, if you get the flames, but then the click back off, you probably have a bad flame proving rod, which is located in front of the burners to one side. You can clean these to get them to work most of the time. Just use a lite abrasive material and clean the rod. Be sure to shut all power off before doing so. Hope this helps and good luck!

Gas dose not come on

The blinking light is giving you a trouble code for the unit. It should have a label or something inside the unit or in your owners manual to let you know what the code means. Count the number of blinks. It should repeat over and over.

Goodman furnace fault light blinks 3 times it kicks on but does not blow heat?

Hi, what you have to do is where you see this light flashing, there is a circuit board. Remove the panel. If everything goes black, you have a door switch on the perimeter that you can tape down to restore power to the furnace. On the panel, you will find a error code sheet glued on it telling you what the flashes mean. 3 flashes may say you have an open pressure switch, or 4 may say the inducer motors off or something else. It will almost troubleshoot itself. Find out what the 3 flashes mean and if you cant figure out what to do, contact me and I will walk you through it. It sounds like you have a dirty flame sensor, or an intermittent problem in the ignitor module. Check it out as it will tell you.

The switch inside the door lock mechanism is stuck down making the unit think it is still locked.  the switched is located next to the hook that locks your door.
