Open official source ↗DC-link voltage sensor error
Stop if there is smoke, a burning smell, damaged wiring, repeated breaker operation, or refrigerant leakage. Do not probe live wiring, inverter terminals, or control boards. Record the displayed code, stop repeated restarts, and contact Samsung Mexico technical support or an authorized service centre for diagnosis.
Typical symptoms
Fault area and what the code does not prove
Separate the manufacturer-defined condition from components that still need exact-model diagnosis.
Safe next steps

- 2Keep the appliance in a safe state and use only the external checks named in the official source.
- 3If the condition remains, stop and arrange qualified service; do not open panels or bypass a safety device.
Step-by-step diagnosis
- 1Photograph the complete E469 display before changing controls or removing power
- 2Confirm that the full model number is covered by this scope: Samsung air conditioners covered by the official Mexico display-code support table
- 3Confirm that the observed condition matches the published meaning: DC-link voltage sensor error
- 4Published check — Do not probe live wiring, inverter terminals, or control boards
- 5Published check — Record the displayed code, stop repeated restarts, and contact Samsung Mexico technical support or an authorized service centre for diagnosis
- 6Stop at the published service boundary after these actions
- 7do not add a restart or test cycle that Samsung does not specify for E469
- 8Published check — Give service the E469 photo, full model and serial number, when it appeared, and the result of every published external check
- 9Stop at the published service boundary after these actions; do not add a restart or test cycle that Samsung does not specify for E469
Service-safe actions
- 1Do not probe live wiring, inverter terminals, or control boards
- 2Record the displayed code, stop repeated restarts, and contact Samsung Mexico technical support or an authorized service centre for diagnosis
- 3Give service the E469 photo, full model and serial number, when it appeared, and the result of every published external check
Repair planning
E469 cost planning: The published load, obstruction, or restart check costs €0. A drive-system diagnosis is generally planned within €140–€320 before parts, with the component and labor quoted separately.
E469 time plan: 10–20 minutes for the permitted E469 external checks and one controlled test; professional drive diagnosis commonly takes 45–90 minutes.

E469 parts decision: E469 identifies DC-link voltage sensor error. It does not alone confirm a motor, inverter, belt, bearing, rotor, wiring harness, or control board; the exact failed item must be diagnosed on the listed model family.
What not to do
- Wait for all movement to stop
- Do not rotate a powered mechanism, bypass an interlock, test inverter output, or order a motor from E469 alone
- Do not run an extra test cycle after the source tells you to stop or arrange service for E469
Preventive maintenance
- 1Follow the exact Samsung maintenance schedule for the air conditioner and keep the model, serial number, and service history available
- 2If E469 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis
