Hello, one minute while I get some information together.
Hello and thanks for using this service! If you are a JA Member I would like to personally thank you and welcome you back! I am HVAC Guru an extremely experienced tech on the site and I try to get to as many customers as I can. NOTE it takes time for me to type research and add links so please wait for me to respond back I can only do this so fast. Secondly, I do not know your skill level so please try and let me know if I am going beyond your knowledge or comfort zone thanks! I strive for a 5 star rating from everyone especially our JA members.
This is a pressure switch closed code with the inducer on, check to make sure the pressure switch is open and the pressure tube and ports are clear on the unit. If they are blocked or the pressure tube is stuck closed this code will come up.
All I ask is please use the Star Rating Link at the top of your page before leaving, that is the only way I am credited through the site, tips are appreciated.
Disconnect a wire from the pressure switch and then start the unit when the inducer comes on then reconnect the wire and see what happens.
Did you disconnect it from the pressure switch and do you see the error code list on the panel sheet on the unit?
If you have disconnected a wire from the switch and it still shows that code you would have a bad board. Nothing else would cause that issue.
Yes turn it off then remove the wire turn it on and when the inducer(exhaust motor) comes on reconnect it
No it does not matter you will need a new board then for sure.
You had a switch?
