What Does York Error Code R7 Mean?
The R7 error code on your York furnace indicates an 'Ignition Lockout'. This means the furnace attempted to ignite the burners multiple times but failed. After several failed attempts, the control board locks out the ignition sequence as a safety measure to prevent a dangerous buildup of gas. This lockout can be triggered by various issues within the ignition system or problems with the gas supply itself. Continuing to try and reset the furnace without addressing the underlying problem is risky and could lead to a hazardous situation. It's important to address this issue promptly to restore heat and ensure safe operation.
Common Causes of York Code R7
- Faulty or weak igniter (hot surface igniter or spark igniter)
- Blocked or restricted gas supply to the furnace
- Defective gas valve not opening properly
- Flame sensor not detecting the flame
- Malfunctioning control board
