Rheem Imperial High Efficiancy Natural Gas Furnace - 3 flashes Internal Error

I have lost heat 3 times this winter. The first time I had the board replaced and the Hot surface ignitor replaced and got heat for about 3 weeks.

The second time I had been hearing this squeeking noise coming from the inducer motor and replaced that. I got heat for another couple of weeks.

Now when I turn on the heat the inducer motor comes on and instead of hearing a click and the hot surface ignitor comming on I get 3 flashes from the green LED indicating a internal error.

I was hoping some one might be able to help me as I am not sure what is causing the internal error and have basically replaced everythign in the furnace now.

Usually, but not always, an "internal error" indicates a problem with the furnace control board.
The fact the inducer comes on but the ignition sequence will go no further might point to a pressure switch not closing.
