Reading the furnace display

A furnace reports faults on a small status LED on the control board, seen through the sight glass in the blower door, or on a two-digit display. Watch a full cycle of the pattern and count the flashes, including the pause between groups, before you decide what you saw. The code chart is on the label inside the blower door.

This page lists the fault codes this brand documents, with likely causes and a short repair path. The codes apply to model numbers such as PG8MAA and PG8JAA; check the label on your unit to confirm yours.

What causes Continuous On

How to fix it

If you smell gas, leave the building and call your gas utility from outside; do not touch switches or the furnace. Switch the furnace power off before you open the blower door or touch the igniter or flame sensor, and call a licensed HVAC technician if you are not sure.

The code meaning comes from the manufacturer document listed under Sources. The causes and steps below are general troubleshooting guidance, not the manufacturer's service procedure.

  1. If the furnace is not heating, check the thermostat is set to heat and the set temperature is above the room temperature.
  2. Check that the thermostat has power and fresh batteries if it uses them.
  3. Wait a few minutes after the thermostat calls for heat, because the inducer and igniter start up in sequence.
  4. If the thermostat is calling and nothing happens for several minutes, watch the LED for a flash code during the start-up sequence.
  5. Restore power and run a heating cycle. If the code returns, call a licensed HVAC technician and give them the code, the board label and the furnace model number.

Questions

What does Continuous On mean on a Payne furnace?

A steady LED on a Payne furnace control board means the board has 24 volt power and has no fault stored. It is a normal status, not an error.

Can I reset the furnace myself?

The control can be reset by switching power off at the furnace switch or breaker for about 30 seconds, which clears some lockouts. If the same code returns, the fault is still present and the control will shut the furnace down again. Never bypass a safety switch to keep it running.

When should I call a technician?

Call a licensed HVAC technician for anything involving gas, the pressure switch, the limit or rollout switches, the igniter, the flame sensor or a control board replacement, or if the code keeps coming back after the simple checks.
