Re: URGENT Furnace stoped working!

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.
