Payne PG80ESA Error Code 14: Ignition Lockout
What Does Code 14 Mean?
Status code 14 on the Payne PG80ESA indicates an ignition lockout. Unlike most other lockout codes on this furnace, code 14 will NOT automatically reset — you must manually cycle the power to clear it. The furnace attempted to ignite multiple times but could not confirm a flame, so it has shut down for safety.
During a normal heating cycle, the inducer motor starts, the hot surface igniter glows, the gas valve opens, and the flame sensor verifies that combustion is occurring. If the flame sensor cannot detect a flame — even if gas is actually burning — the control board shuts off the gas valve. After several failed attempts (code 34 occurs first, then escalates to code 14 after four tries), the furnace enters this lockout state.
The most common cause is a dirty flame sensor with oxide buildup that prevents it from detecting the flame properly. The second most common cause is the gas supply being turned off, either at the manual shutoff valve near the furnace or at the gas meter. A defective hot surface igniter or inadequate flame carryover are also possible causes, but these typically require professional diagnosis.
Common Causes
When to Call a Professional
Contact a licensed HVAC technician if:
- The burners still fail to stay lit after cleaning the flame sensor
- The hot surface igniter does not glow during the ignition sequence
- You can hear gas flowing but it does not ignite
- The flame appears yellow, lazy, or rolls out of the combustion chamber
- Code 14 occurs repeatedly even with a clean flame sensor and open gas supply
