What 1C/1C / 1C/2C (665-prefix) means

A Kenmore range with a model number beginning 665. — a Whirlpool-built platform with a two-part display — shows 1C/1C when a key on the keypad is stuck or the keypad itself is defective, and 1C/2C when the keypad wire harness is unplugged. Both describe the touch keypad circuit, not the heating elements. You will see the paired code flash on the display, and the oven or cooktop may ignore button presses or behave as if a key is being held down.

Common causes of 1C/1C / 1C/2C (665-prefix)

A stuck or pressed-in key on the keypad
Keypad ribbon or harness connection to the control
The keypad itself
The electronic oven control reading the keypad

✓ One safe check you can try

1. Look at the keypad for a key that is stuck, swollen, or sitting under spilled food. 2. Wipe the keypad gently with a barely damp cloth, and dry it. 3. Unplug the range for 3 minutes to reset the oven control, then plug it back in. 4. Try a few keys. If the code returns right away, stop and let us look at it.

! Why to stop there

A reset clears a one-time glitch but cannot cure a worn keypad or a loose harness
We check which of the two codes keeps returning to separate a stuck key from a disconnected harness
We test the keypad circuit before replacing anything and quote in writing first

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

1C/1C / 1C/2C (665-prefix)1C/1C / 1C/2C (665-prefix) questions

Do 1C/1C and 1C/2C point to the same part?

On this 665 platform, 1C/1C points to a stuck key or defective keypad, while 1C/2C points to the keypad wire harness being unplugged. Both are keypad circuit codes rather than heating problems.

Is it safe to use the range?

The code is a keypad message, so the oven may simply not respond to buttons. If a cooktop burner will not shut off at its knob, switch the range off at the breaker.

What helps you diagnose this by phone?

Tell us the code exactly as shown, whether the keys respond at all, and whether anything was spilled on the panel. That helps us bring the right checks, and the price is written before work begins.
