WE are going to need a gas pressure tester or manometer to verify pressure into and out of the valve,. Fo you have any letters in front of those numbers in model?
Sounds good.Look forward to helping with this.
Thanks for the model. I see it does have a board with an error code. The error is determined by short and long flashes .For example if pressure switch is opening we would get three short then one long flash. Do you et a code on board when it goes out
OK the 12 just says call dealer for service.Lets get that gas pressure tester and see what kind of pressure we have in and out of valve.There should be ports on valve for testing.
That is strange that we would have different charts. But if yours is the normal code, I am suspecting issue to be with pressure or the valve. By the way here is my chart.
I am sure yours is correct. just strange they would have a different chart on website. The 12 is a good code on Carrier furnaces, which is the company that makes Brant and Payne so I am confident it is right.We will continue after checking gas pressure .We should have at least 10.5"WC to valve and no more than 14"WC
Usually if it is an issue with pressure switch we would get a different code. See chart on your unit .
Thanks let me know what you find.
Look forward to hearing back
