Payne Furnace: 1 Flashes

A Payne furnace LED pattern starting with 1 flashes matches 7 documented codes: 10.1, 11, 12, 13, 14, 14.2, 14.3. Watch the full pattern (short vs. long flashes) to tell them apart — all 7 are explained below.

Code 10.1: L1 polarity fault - the polarity of the incoming 115 V power is reversed

Hard lockoutShown as: Rapid flashing LED; 10.1 on the 3-digit display

L1 polarity fault - the polarity of the incoming 115 V power is reversed.

Manual wording: “10.1 L1 POLARITY FAULT - Rapid flash LED. Polarity of incoming 115V power is reversed.”

Documented for: PG80MSU

Likely causes, most common first

  1. Line voltage (115 V) hot and neutral reversed at a junction
  2. Improper low-voltage (24 V) transformer phasing on twinned units

When to call a technician

Fixing 115 V polarity requires opening junction boxes on live wiring - call a licensed technician or electrician.

A Payne furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.

Code 11: No previous code

StatusShown as: 1 short flash, 1 long flash

No previous code. Nothing is stored in the control's fault memory; stored codes erase automatically after 72 hours.

Manual wording: “11 NO PREVIOUS CODE - Stored codes are erased after 72 hours. Run system through a heating or cooling cycle to check system.”

Documented for: PG92ESA, PG95ESA, PG96VTA

Likely causes, most common first

  1. Normal - no stored fault
  2. A previous fault aged out after 72 hours or was manually cleared

What you can safely check yourself

  • Nothing to fix - run the furnace through a full heating cycle and see whether a real code appears

When to call a technician

If the furnace misbehaves but only shows 11, a technician should watch a live cycle to catch the fault as it happens.

Code 12: Blower on after power up - normal operation

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

  1. Power was interrupted and restored during a call for heat
  2. 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.

Code 13: Limit circuit lockout

Soft lockoutShown as: 1 short flash, 3 long flashes

Limit circuit lockout. The limit or flame rollout switch has been open longer than 3 minutes. The control locks out and auto-resets after 3 hours.

Manual wording: “13 LIMIT CIRCUIT LOCKOUT - Lockout occurs if the limit or flame rollout is open longer than 3 minutes. Control will auto-reset after 3 hours. See code 33.”

Documented for: PG92ESA, PG95ESA, PG96VTA, PG80MSU

Likely causes, most common first

  1. Restricted vent or improper vent sizing
  2. Dirty filter or restricted duct system
  3. Blower motor not functioning
  4. Defective switch or connections
  5. Inadequate combustion air supply

What you can safely check yourself

  • Check and replace a dirty air filter
  • Make sure supply registers and return grilles are open and unblocked
  • Make sure the furnace blower door is fully closed

When to call a technician

A 3-minute limit trip means the furnace was really overheating or not venting. Have a technician confirm why before running it again; a tripped flame rollout switch must never be reset without finding the cause.

Code 14: Ignition lockout

Soft lockoutShown as: 1 short flash, 4 long flashes

Ignition lockout. The furnace failed to ignite the gas and prove flame in four attempts. The control auto-resets after 3 hours.

Manual wording: “14 IGNITION LOCKOUT - System failed to ignite gas and prove flame in 4 attempts. Control will auto-reset after 3 hours. See status code 34.”

Documented for: PG92ESA, PG95ESA, PG96VTA, PG80MSU

Likely causes, most common first

  1. Igniter, flame sensor, or gas valve problem - see code 34
  2. Low inlet gas pressure or a closed manual gas valve
  3. Loss of control ground continuity

What you can safely check yourself

  • Confirm other gas appliances in the house work, so you know gas service is on
  • Turn the furnace off at the service switch for a minute and back on once for one clean retry

When to call a technician

Ignition faults are inside the burner compartment of a live gas appliance. Have a technician check the igniter, flame sensor, gas valve, and gas pressure.

Code 14.2: Flame lost lockout - the flame signal was lost three times after the heating blower on-delay

Safety faultShown as: Major code 14 flashed on the LED (1 short, 4 long); 14.2 on the display

Flame lost lockout - the flame signal was lost three times after the heating blower on-delay. Auto-resets after 3 hours.

Manual wording: “14.2 FLAME LOST LOCKOUT - Flame signal was lost 3 times after heating blower on delay. Control will auto-reset after 3 hours. See status code 34.3.”

Documented for: PG80MSU

Likely causes, most common first

  1. Incorrect manifold pressure and gas firing rate
  2. Gas inlet pressure fluctuations
  3. Improper pressure transducer operation
  4. Flame sensing problem - see code 34

What you can safely check yourself

  • Check that the air filter is clean and vents are open

When to call a technician

Repeated loss of an established flame is a combustion fault. Have a technician verify gas pressure and flame sensing before running the furnace.

Code 14.3: Flame lost lockout - the flame signal was lost seven times during a single heat request

Safety faultShown as: Major code 14 flashed on the LED (1 short, 4 long); 14.3 on the display

Flame lost lockout - the flame signal was lost seven times during a single heat request.

Manual wording: “14.3 FLAME LOST LOCKOUT - Flame signal was lost 7 times during a single heat request. See status code 34.2 to 34.4.”

Documented for: PG80MSU

Likely causes, most common first

  1. Incorrect manifold pressure and gas firing rate
  2. Gas inlet pressure fluctuations
  3. Improper pressure transducer operation

What you can safely check yourself

  • Check that the air filter is clean and supply and return vents are open

When to call a technician

Do not keep resetting the furnace. Seven flame losses in one heat call needs a technician to check gas supply and the combustion setup.
