Burner ignites but shuts off 2 seconds later?red light blinks 7 times in a row?no heat.

If your pressure switch has ever been replaced, make sure that it was replaced with an OEM pressure switch, because it can cause some strange behavior on your furnace. Check out this video, as this is touched upon in it: Amazon Furnace Parts:

Goodman Dependable 92, ignitor and fan comes on for 3 seconds, furnance does not turn on. Goes through 3-4 cycles, then shuts down furnance. If it is the flame sensor, where can one buy parts?

Do the burners come on? If so then yes it probably is the flame sensor if not then there is another issue not the flame sensor. The flame sensor could just be dirty take the flame sensor out and clean it with a piece of emery cloth or lite sand paper and put it back in and this should get the burners to stay on.

Lennox intermitent flame problem

Yes the flame sensor is not allowing the ignitor to start, you will need to remove the flame sensor, and clean the black carbon build up from the stem of the flame sensor, replace the flame sensor and turn the furnance back on, this will correct the problem.

I have a york diamond 90 diagnostic 1 flash lock

open the top of your unit so that you can see into the burner box
what your looking for should be an orange wire that leeads up to a metal rod
that metal rod should be in the way of the flame when unit is on
this is your flame ground,,, or more commonly known as the flame sensor,,, take this out and goive it a good brush with some steel wool
and reassemble,,
this should clear up you problem

Gas does not stay on.

The unit uses "flame rectification" (basically it is sensing a pulsing dc current) to sense the flame and is very sensitive to bad/poor ground and also to a dirty flame sensor. The gas ignition does not shut off the valve ...the board is not sensing the current thru the flame so its reading a "no Fire" fault and shutting down.

Clean the flame sensor with sandpaper till its brite and shiny and check all connections to make sure they are tight and very clean, especially the ground to the board and also to the furnace itself (sometimes we have to actually drive a ground rod near the furnace itself or use some other means to make sure that a proper gorund is achieved).

If still have a problem; I would try another board, the flame sensor is just a piece of solid stainless alloy wire so its really not necessary to change it unless the ceramic insulator is cracked.

Before you buy another board, I would suggest that you have a pro look at it.

Error code 12

Error code 12 is a genaric "Flame Failure" code. I suspect that the flame is not hitting the flame sensor or that the sensor is bad. You will need to get to the sensor located on the far left hand side of the unit. If you have the owners manual, it's part #123. Remove it and clean it off. Make sure it is placed back in the heater properly aligned and all the way in. Then try and light it. If it does not stay lit, it may need to be replaced but check out the burner tray for debris not allowing the flame to travel all the way to the sensor. You will have to remove many parts to get to the burner assembly.
