The name is Serguei. I have a York furnace. yp9c080c16mp12ca

Customer Question
Hello. The name is***** have...
Hello. The name is***** have a York furnace. yp9c080c16mp12ca I get 3 flashes error code. Cleaned the tubes, made sure they click. The 3 flashes code happen "before" the ventor motor even begins, not after. But if I disconnect the pressure sensor (a 3 wire sensor that connects with tubings between ventor motor assembly/pressure switch/pressure sensor. Then Ventor motor at least starts. changed control board as well. Same thing is happening
JA: Thanks. Can you give me any more details about your issue?
Customer: 3 flashes error code. Which means pressure switch stays open. But error code comes before the ventor motor even starts. Pretty much within 2-3 seconds of beginning operation. Changed Control Board. Same problem. If I disconnect the Pressure Sensor. The Ventor Motor 'does' start, giving me a 3 flashes code after a few min of trying to make things close.
JA: OK got it. Last thing — HVAC Technicians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied).

I'm given an error that pressure switch fails to close, even before ventor motor starts. And you think it's the pressure switch that's failed?
Customer reply replied 1 year ago
Okey. I've ended up calling York and it's not the pressure switch's problem. One of the wires on the sensor, that 3 wire thingy is broken. You guys have been no help. Sorry.
