1C1C and 1C2C share one JennAir message about the keypad and its wiring. A one-minute breaker reset is the only owner step.
Model compatibility: JennAir reuses codes across series and model years, so 1C1C, 1C2C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
1C1C and 1C2C may indicate a problem with the user interface/keypad or the associated wiring.
One message, two codes
JennAir gives 1C1C and 1C2C exactly the same wording on its range and wall oven pages, so they are covered together. The wording is cautious. It says the User Interface/Keypad could be at fault, and so could the wiring that belongs to it.
What that points to
In everyday terms, this is the pad of keys or touch surface where you enter what the oven should do. A code naming it fits a control that is failing to read or respond to input as it should.
Owner reset from the manufacturer
Go to the breaker panel and turn off the circuit for the oven or range, then wait a full minute.
Turn the breaker back on.
Stay close to the appliance for roughly sixty seconds, looking for 1C1C or 1C2C on the display.
Check the oven operates as usual.
A clean display afterward means the reset did the job. If the code reappears, JennAir has nothing more for the owner.
When a technician is the answer
A keypad code that returns needs service. Taking the control apart to check its connections is no homeowner task, and the page doesn’t suggest it. Before calling, make a note of the code that showed, and of whether key presses did anything ahead of it.
Other control-related codes
F1-5 and F1-8: also blame the keypad, paired with the oven control
If 1C1C or 1C2C outlasts the breaker reset, the Los Angeles number is (310) 622-9465. Name the code and say the breaker has been off for a minute already. Our wall oven repair page gives an overview.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
