Bryant Furnace Code 25.7
Hard lockoutShown as: Major code 25 flashed on the LED (2 short, 5 long); 25.7 on the display
A non-condensing program was detected in a condensing model furnace.
Manual wording: “25.7 NON-CONDENSING PROGRAM detected in a condensing model.”
Documented for: 926TC, 912SE
Likely causes, most common first
- Wrong program loaded into the control after a board replacement
When to call a technician
The control needs the correct program number from the rating plate loaded by a dealer.
A Bryant furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
