Quick answer
E162 means the indoor unit EEPROM (memory chip) has a read/write error. The PCB cannot load its configuration data.
What E162 means
The EEPROM is a small memory chip on the indoor PCB that stores the unit's configuration — model parameters, sensor calibration, and operating limits. When the board cannot read this chip, it displays E162 and refuses to start.
How to fix it
This is usually a PCB-level fault. A power reset sometimes clears a temporary glitch, but a persistent E162 usually means the indoor PCB needs replacing.
What does the E162 code mean?
E162 is an indoor EEPROM (electrically erasable programmable read-only memory) error. The control board cannot read or write its configuration data.
Common causes
- Corrupted EEPROM data (power surge or brownout)
- Faulty EEPROM chip on the indoor PCB
- Indoor PCB failure
- Loose ribbon cable or connector on the PCB

How to fix the E162 error
Power cycle
Turn the breaker off for 10 minutes, then restore. This clears temporary EEPROM glitches.
Check for power-supply issues
If your area has frequent brownouts or surges, install a surge protector for the AC circuit.
Inspect the indoor PCB
Look for burn marks, swollen capacitors, or loose connectors.
Replace the indoor PCB
If E162 persists after a power cycle, the PCB typically needs replacement by a Samsung technician.
Safety first: PCB replacement involves mains wiring. This should be done by a qualified technician.
Part you may need: Indoor PCB (main control board)
A technician can sometimes reflash the EEPROM if the chip itself is intact but the data is corrupt.
Frequently asked questions
Can a power surge cause E162?
Yes — voltage spikes can corrupt the EEPROM. A surge protector helps prevent recurrence.
Is the PCB expensive?
It varies by model, but indoor PCBs typically cost more than sensors. Get a quote from Samsung service.
