What C-A0 / C-A1 / C-A2 means

C-A0, C-A1, and C-A2 appear on Samsung microwaves and are listed as a functional error. The microwave has found a problem with how it is operating and stops, showing the code. The listing gives the type of error but not a single part, so we describe it by product type rather than model. You will see the code on the display and the microwave will not run a normal cooking cycle.

Common causes of C-A0 / C-A1 / C-A2

  • A control or a function that is not responding as expected
  • Moisture that has gotten into the microwave
  • A connection that has loosened
  • A one-time upset after a power interruption
✓ One safe check you can try

1. Unplug the microwave, or switch its breaker off. 2. Let it dry first if moisture could have gotten in. 3. Otherwise wait a full 60 seconds before turning the power on. 4. If C-A0, C-A1, or C-A2 appears again, stop using it and request service.

! Why to stop there
  • A functional error covers many possibilities, so we start by finding out which function the control is not getting back.
  • We test the control and its connections rather than guess from the code alone.
  • We give you a written price before work and a 30-day workmanship warranty.
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.

C-A0 / C-A1 / C-A2C-A0 / C-A1 / C-A2 questions
What is a functional error on a microwave?

It is listed as a functional error. The microwave detected something not working as it should and stopped, but the code does not name a single part.

Is C-A1 different from C-A0?

They are listed together in the same functional error group, so the first steps are the same: unplug or switch off the breaker, wait 60 seconds, and restart. A return of the code means a test.

Can I reset it myself?

Unplugging or switching off the breaker for 60 seconds is the safe reset. If the code returns, we test the control. Do not open the microwave case, because parts inside can hold a charge.
