Quick answer

On a Samsung microwave, C-10 (like C-11 and C-12) is an error with the gas, Easy or PH sensor, depending on the model. Samsung says to unplug it or switch off its breaker for 60 seconds and ask for service if it persists.

Safety first

Stop and check this first

  • Do not take the microwave's outer cover off to look for the fault: inside there is a high voltage capacitor that can hold a lethal charge even when unplugged. The magnetron, door seals and safety interlocks are for authorised service only.

Safe checks you can perform

  • Exact code in the C-1 family
  • 60 second reset
  • Watched test with a load

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Sensor and connector measurement
  • Do not attempt this professional task: Test of the programme that uses the sensor

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Sensor and connector measurement

    What they doThe authorised technician measures the gas, Easy or PH sensor and checks its connector against the service manual values, after discharging high voltage as the procedure requires.

    They must show youthe sensor's measured value against Samsung's specification.

    In writingthe measured value, the cause and, if the sensor is replaced, its part number.

  2. Test of the programme that uses the sensor

    What they doAfter the repair, the technician runs the programme that showed the code, with a load.

    They must show youthe programme finished with no code.

    In writingthe programme tested, the result and the date.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Exact code in the C-1 family

    No special tools

    Who:
    you, no tools.
    How:
    note whether it shows C-10, C-11 or C-12 and the programme you were using.
    Result that matters:
    the exact code and the programme.
    If it is one of the three:
    it relates to the gas, Easy or PH sensor per Samsung's table.
    If it is another code:
    look it up in the table; this procedure may not apply.
    Evidence to keep:
    photo of the display.

  2. 60 second reset

    No special tools

    Who:
    you, at the plug or breaker.
    How:
    unplug the microwave or switch off its breaker for 60 seconds, as Samsung says, then reconnect.
    Result that matters:
    whether the code clears.
    If it clears:
    run a short test with a load.
    If it persists:
    Samsung points to its service centre.
    Evidence to keep:
    note of the reset and the result.

  3. Watched test with a load

    No special tools

    Who:
    you, with a microwave-safe container of water.
    How:
    set a short manual time with a microwave-safe container of water and watch. Do not run it empty.
    Result that matters:
    whether the code returns during use.
    If it does not return:
    it was a one-off; note if it repeats with the programme you used.
    If it returns:
    ask for a sensor check with your notes.
    Evidence to keep:
    note of the programme and when the code appeared.

What it means

Samsung Canada defines C-10, C-11 and C-12 as an error with the gas, Easy or PH sensor, the name that sensor takes depending on the model. The table gives only the family, without saying whether the sensor is open or shorted; for that it lists codes E-11 to E-14 and E-41 to E-44 separately. Samsung UK says most codes need a technician to verify them. The code can come from the sensor, its connection or the board. The table covers Samsung microwaves sold in Canada, and Samsung warns that codes may differ for units bought elsewhere.

Symptoms and causes

Probable causes · in order

  • Gas, Easy or PH sensor out of rangePossible

    This is Samsung's definition for the C-1 family. It fits if the code returns after the 60 second reset and appears as soon as the unit is used.

  • Sensor connection or wiringPossible

    The sensor may be fine and the signal lost on its way to the board. The technician separates them by measuring the sensor and checking its connector.

  • One-off control faultLess common

    Samsung suggests the 60 second reset first. If the code does not return in normal use afterwards, it was a one-off state.
