- Bryant 926TC two-stage variable-speed ECM multipoise condensing gas furnace: The furnace locked out after failing to light or keep flame. Minor codes cover 4 consecutive ignition tries (14.1), flame lost 3 times after 70s of heating (14.2), 7 loss of flame events during a heat request (14.3) and 7 LPS open events during a heat request (14.4).
Is it safe to keep running? Check the steps below first. If the lockout repeats, call a licensed technician. The label lists the hot surface igniter, flame sensor, gas valve and gas pressure as things to check.

Check this first
Only steps a homeowner can do safely. Do not open electrical panels or the burner area.
- Check the thermostat is set to Heat, set above room temperature, and has fresh batteries if it uses them.
- Make sure the manual gas shutoff valve is open, following the lighting instructions on the furnace label.
- Turn the furnace power off at the switch or breaker, wait one minute, then turn it back on to see whether the code returns.
- Look outside at the furnace vent and intake pipe ends. Make sure snow, leaves or a nest are not blocking them. Look only, do not touch the pipes.
- Look at the condensate drain line and trap (if you can see it without removing any panel) for a clog, kink or standing water.
🛑 Stop and call a licensed pro if
- If the lockout repeats, call a licensed technician. The label lists the hot surface igniter, flame sensor, gas valve and gas pressure as things to check.
- If the lockout repeats, call a licensed technician. Flame sensor, igniter, gas pressure and venting checks are service work.
- You smell gas. Leave the house, do not touch switches, and call your gas utility from outside.
- Flame rollout, limit or pressure switch codes that come back after one reset.
- Anything involving the control board, gas valve, flame sensor, igniter or venting.
- A carbon monoxide alarm sounds. Get everyone outside and call 911 or the fire department.
Safe first steps for any Carrier and Bryant code
- Count the LED flashes through the blower door window before you switch anything off. Cutting power can clear the code.
- Replace or clean the furnace air filter.
- Check the thermostat: correct mode, set above room temperature, and fresh batteries.
- Make sure the furnace power switch and breaker are on. If the furnace has locked out, turning the power off and back on once restarts it.
- Make sure the gas valve is in the ON position, following the lighting instructions on the furnace label only.
- On high-efficiency furnaces, look at the outside vent and intake pipes for snow, ice, leaves or nests (look only, do not take pipes apart).
