Carrier Furnace Code 14: Ignition Lockout

If you smell gas or a CO alarm sounds, leave the home and call the gas utility or 911 from outside.

Code 14 means the furnace has stopped trying to light. In Carrier's guides, an ignition-proving failure (code 34) gets three more tries; if those fail, the control locks out with code 14 and auto-resets after 3 hours. The causes to check are the ones listed under code 34.

Does code 14 reset on its own?

Carrier’s guides say the control will auto-reset after 3 hours.

What to do before you call

  • Write the code down before you touch anything. Carrier’s 58MVP (Series 170 & 180), 58MVB, 58UVB troubleshooting guide (58-06T) starts with: “DO NOT REMOVE BLOWER ACCESS PANEL! Record status of AMBER LED.” Turning off power can also clear the code history.
  • Everything else on these lists (gas valve, pressure switches, wiring, venting, the control board) is technician work.
