Payne Furnace Code 12
StatusShown as: 1 short flash, 2 long flashes
Blower on after power up - normal operation. The blower runs for 90 seconds because power was restored during a call for heat, or the call ended during the blower on-delay.
Manual wording: “12 BLOWER ON AFTER POWER UP - (115V OR 24V) - Normal operation. Blower runs for 90 seconds, if unit is powered up during a call for heat (R-W closed)”
Documented for: PG92ESA, PG95ESA, PG96VTA, PG80MSU
Likely causes, most common first
- Power was interrupted and restored during a call for heat
- Thermostat call ended during the blower on-delay period
What you can safely check yourself
- Nothing to fix - this is normal after a power blip or after switching the furnace back on
When to call a technician
If code 12 keeps appearing without any power outages, have a technician check for a loose 115 V connection or a failing door switch.
A Payne furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
