Control board memory error. Here is what it means and how to clear it, easiest fix first.

The indoor unit's control board can't read its stored settings correctly; the data in its memory chip (EEPROM) is wrong or missing. E163 points to the option settings that tell the board which model it is fitted to.

Samsung uses an E or a C as the first letter depending on model year, so E162 and C162 are the same fault. On many wall-mount units this shows as E1 (or C1) followed by 63. Meanings here come from Samsung service and installation manuals for specific model families; codes vary by series and region, so check your owner's or service manual.

Safety first: unplug the air conditioner (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Samsung E162 / E163

  1. Reset the power at the breaker

    Switch off the breaker that feeds the air conditioner (some systems have separate breakers for the indoor and outdoor units, so switch off both). Wait about five minutes, switch the power back on and restart the unit to see if the code clears.

  2. Note the code and when it appears

    If the code returns, write down exactly what the display shows, the model number from the indoor unit's label, and whether it appeared at start-up or after a power cut. The technician will need to re-enter the board's option settings for your exact model.

When to call a technician

Option codes have to be re-entered with service tools, and a faulty board must be replaced, so book an authorized technician.
