Error code1C1C / 1C2C
ApplianceMicrowave
Quick answer
1C1C and 1C2C on a JennAir built-in microwave mean the same keypad or wiring fault. One breaker reset is listed; after that, service.
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
JennAir lists a possible User Interface/Keypad or wiring problem for 1C1C and 1C2C.
Same fault, two numbers
On the built-in microwave help pages, 1C1C and 1C2C read identically: there may be trouble in the keypad assembly, User Interface/Keypad in JennAir’s words, or in its wiring. Seeing either number means the same thing.
The user interface, briefly
The term covers whatever you press to operate the microwave, plus its electronics. The wiring named in the message is the link back to the remaining control. JennAir does not say which of these has failed or why, so the display alone cannot narrow it down.
Owner reset from the page
Flip off the breaker or breakers that supply the microwave.
Leave things off for 60 seconds.
Flip the breaker back on.
Observe the display for another 60 seconds, looking for the code.
Use the microwave to confirm normal operation.
That is every owner step on offer. If the code is back after the reset, book service, because no further steps are listed.
Keep the cabinet shut
Getting at a keypad or its wiring means opening the microwave. Parts inside may be hazardous even when power is disconnected, which makes this work for a technician and not a home fix.

Should 1C1C or 1C2C return, ring (310) 622-9465 to arrange a visit. Have the model label details to hand and mention the one-minute breaker reset. Read about microwave repair here.
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.
