C-F2
Samsung C-F2 on a microwave: touch keypad communication fault
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On a Samsung microwave, C-F2 (or -tE-) means communication with the touch keypad was abnormal. Samsung says to press Stop to try again; if the code keeps coming back, the service centre should check it.
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
- Stop and retry
- 60 second reset
- Short cycle with a load
Leave these tasks to a qualified professional

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.
Keypad, cable and board check
What they doThe authorised technician checks the link between the touch keypad and the control board with the service manual procedure, after discharging high voltage.
They must show youthe test that places the fault in the keypad, the cable or the board.
In writingthe failing part, its part number and the reason for replacing it.
Every key test
What they doAfter the repair, the technician presses every key and runs a cycle with a load to confirm communication is stable.
They must show youevery key responding and a full cycle with no code.
In writingthe test done, 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.
Stop and retry
- Who:
- you, no tools.
- How:
- press Stop, as Samsung says, and set the cooking again.
- Result that matters:
- whether the unit accepts the command and the code clears.
- If it works:
- it was a one-off communication glitch.
- If C-F2 returns straight away:
- move on to the unplugged reset.
- Evidence to keep:
- note of how many times it appeared and when.

60 second reset
- Who:
- you, at the plug or breaker.
- How:
- unplug the microwave or switch off its breaker for 60 seconds, then reconnect.
- Result that matters:
- whether the keypad responds normally when power returns.
- If it responds:
- try a short cycle with a load.
- If the code returns without touching the keypad:
- the link or keypad is failing; call service.
- Evidence to keep:
- note of the reset and the result.

Short cycle with a load
- Who:
- you, with a microwave-safe cup of water.
- How:
- set a short time with a microwave-safe cup of water inside and watch. Do not run it empty.
- Result that matters:
- that the cycle finishes without C-F2.
- If it finishes:
- solved.
- If it appears again:
- ask for service with your notes.
- Evidence to keep:
- short video of the code if it comes back.

What it means
Samsung UK defines C-F2, -tE- and -TE- as abnormal communication on the touch key: the control is not receiving the keypad signal properly. Samsung Canada lists C-F2 among communication errors and TE as a touch communication error. Unlike SE, no key is held too long; the signal arrives wrongly. It can be a one-off or come from the keypad, its cable or the board; the code does not separate them. The table is Samsung UK's microwave guide; check your model's manual to confirm the code means the same.

Symptoms and causes
Probable causes · in order
- One-off communication glitchCommon
Samsung only asks you to press Stop and retry, which suggests it is often momentary. It fits if the unit works after Stop and the code stays away.

- Keypad or ribbon cable with a poor connectionPossible
If the code keeps returning despite pressing Stop, the keypad signal is being lost repeatedly and the technician must check the connection.

- Control boardLess common
With keypad and connection fine, the board receiving the signal may fail. It can only be confirmed with the service manual tests.
