What was the error code?

21: Gas valve PF'd. Call a service tech, as you're looking at a new gas valve...

Your code is a 21, indicated by the flashes. This indicates a problem that is more in depth than most DIYers should tackle. It needs to be determined if the valve or the control board is faulty. You can check and ensure all the wiring is connected and not chaffed anywhere, between the valve and the board.

2 shorts and a long equal code 21 according to your LED Status code sheet you posted.

Gas Heating Lockout = You call for service, its not a DIY, This is the gas valve control ( or the valve itself )

Start playing with this and you could blow up the house ...

How come it started to work after I power cycled it? Thanks
Thanks everyone.

When you power cycled, the alarm was cleared, and the valve decided not to stick that round...

Matter of time at this point...

Someone gave detailed suggestions for Bryant furnace error code 21 but I will not be comfortable trying the valve un-sticking part.

They are just suggesting to tap the valve which will sometimes free a sticking valve. If it works, it will get you heat for now, but it is bound to stick again, and will need replacement. But those directions for checking the to see if it is the valve or the control are spot on.

I had a very similar problem with my furnace last year, and it was a defective gas valve. I was not comfortable dealing with that, so I called my furnace guy, he replaced the valve, inspected for cracks / holes in the exchanger (there were none) adjusted the gas / air mix on the burners and cleaned the burners. Furnace works great now. (Well, as well as it has ever worked).

If you cannot get your furnace to restart call your home heating service company and find out if they provide emergency service at no premium cost, many do. Best time to call is during the day although if your furnace will not restart at night they will send a technician out.

But I wouldn't trade it for renting again.

I'm all for DYI and learning, but in this case I'd strongly recommend calling someone qualified to come do the work.

Can you see if the Gas valve is a Honeywell one? If so, it is probably a "Smart Valve" one. Well...those are not so smart because a whole lot of them were faulty and would go bad prematurely after a number of years. My Gas Pack furnace had one and it went bad. You could bump it and it would start working but maybe not again on the next cycle. Of course the unit was well outside of any warranty so I had to pony up several hundred bucks for a new valve. Was only charged .5 hour of service call because I diagnosed the problem for them and all the HVAC guy had to do was change it. My unit is from 95 and is still going. It does have electronic ignition instead of pilot light. Google "Smart Valve" and you will see what I am talking about.

Also make sure the fan for the gas exhaust is working. The moisture from the burning gas can cause these to rust or fail. This happened to my neighbor after only 6 years. Fan rusted and broke apart causing unit to overheat in the heat exchanger because the gas was not getting pulled though.
