Bryant Furnace Error Code 14: Meaning and Fix
Applies to: Bryant furnaces with a two-digit status code LED (checked against the Bryant 310AAV manual).
Also shown as: 1 short 4 long, 1 short, 4 long flashes
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 310AAV; check the label on your unit to confirm yours.
What causes 14
- Flame sensor coated with oxide so it cannot prove flame
- Failed hot surface igniter
- Poor ground or a flame sensor wire touching metal
- Gas supply off, manual gas valve closed or low gas pressure
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.
- Check that the gas shut-off valve at the furnace is open (handle in line with the pipe) and that other gas appliances are working. If you smell gas, leave the building and call your gas utility.
- Switch the furnace power off first. Flame sensor work and igniter work are done with power off.
- If you are comfortable doing so, a coated flame sensor can be cleaned gently with fine steel wool, as the manufacturer instructs. Leave the igniter alone, since it breaks easily.
- If it locks out again, a technician should check the flame signal in microamps, the igniter and the gas valve.
- 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 14 mean on a Bryant furnace?
Code 14 (1 short, 4 long flashes) on a Bryant furnace is an ignition lockout. The furnace tried to light and failed, so the control locked out. It resets itself after three hours. See code 34 for the causes.
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.
