What Does York Error Code R6 Mean?
The R6 error code on your York furnace indicates a 'Gas Valve Failure'. This means the furnace control board isn't detecting the gas valve opening or closing properly, or that the valve isn't responding to the board's commands. The gas valve is responsible for safely controlling the flow of natural gas to the burners for combustion. If the valve malfunctions, it can either prevent the furnace from heating or, more seriously, cause a dangerous buildup of gas. Because natural gas is both flammable and can cause carbon monoxide poisoning, this is a serious issue that needs immediate attention.
Common Causes of York Code R6
- Faulty gas valve solenoid(s) not opening/closing
- Wiring issue between the control board and the gas valve
- Defective furnace control board not sending the correct voltage to the gas valve
- Low gas pressure preventing the valve from operating correctly
- Gas valve is physically blocked or jammed
