Nice work in finding the problem.

Six years isn't that old.

Before you condemn the board or the furnace, I would get a manometer and VOM out and see if that High pressure switch is seeing the required pressure listed on the switch. You could have a venting issue causing the pressure switch to open on occasion. Might be an easy fix.

Keep posting, and get yourself into the pro forums.

O.K. I'll bite.

But first a question, are you a home owner or technician?

As I'm sure you know, this forum doesn't give out troubleshooting info to home owners.

If you are a technician, what troubleshooting have you done up to this point?

From your description, it sounds like the "add-on control board" LED is the one that is blinking.

2 flashes of this LED has to do with Pressure Switch issues.

If you are a homeowner, I would call a service company out to look at your unit. I'm sure they will be able to review the installation of your unit to see if it was done correctly, and then easily troubleshooting the reason for the occasional lock outs.

If you are a technician, get your post count up, apply for membership, once accepted, come into the Pro Forums for info on troubleshooting these pressure switch issues.

That is the best I can do at this stage.

Well thing locked again today looks like it maybe the board anyone work on these units and know the quorks?

Model# KG6TE-080C-VB Have noticed the top light marked ANI on the board will flash sometimes when unit is running?

Gibson two stage 60/80 locking out
