Er PL
LG Refrigerator
Severity: ModerateWhat Does This Error Mean?
The Er PL error means the refrigerator has detected an issue with the power supply — typically an abnormal voltage level. The fridge may shut down components to protect itself from damage. This can be caused by household wiring problems or an internal power supply fault.
Affected Models
- LRMVS3006S
- LRFXS2503S
- LFXS26973S
- LRMVS3006D
- Most LG French door and side-by-side refrigerators
Common Causes
- Household voltage is too high or too low — outside the 110–125V range
- The outlet the fridge is plugged into is loose or has a poor connection
- Extension cord is being used (not recommended for refrigerators)
- Internal power supply board (inverter) has a fault
- Wiring inside the fridge connecting to the power board is damaged
How to Fix It
-
Unplug the refrigerator and inspect the power cord for damage.
Look for cuts, kinks, or scorch marks on the cord. A damaged cord must be replaced.
-
Make sure the refrigerator is plugged directly into a wall outlet — not an extension cord.
Extension cords can cause voltage drop that triggers the Er PL error.
-
Check the outlet with a voltage meter or plug in a lamp to confirm the outlet is working.
A loose outlet with a bad connection can cause intermittent voltage drops.
-
Check your home's circuit breaker panel for any tripped breakers.
The refrigerator should be on a dedicated 15 or 20 amp circuit.
-
Plug the refrigerator back in. If the error immediately returns, the internal power board needs inspection.
Contact an LG certified technician to test the inverter and power supply board.
When to Call a Professional
If the outlet and household voltage check out fine but the error persists — the inverter or power supply board may need replacement. Expect costs of $150–$350 for an inverter board replacement. Contact an LG certified technician for diagnosis.
Frequently Asked Questions
Can a power surge cause the Er PL error?
Yes — a power surge or brownout can trigger Er PL. If it happened after a storm or power outage, try unplugging for 10 minutes and restarting. If it keeps happening, the internal power board may have been damaged by the surge.
Should I use a surge protector with my LG refrigerator?
Yes — LG recommends using a surge protector or voltage regulator with their refrigerators. This protects the sensitive electronics from power fluctuations that can cause Er PL. Make sure the surge protector is rated for refrigerators (high joule rating).
Will the Er PL error damage my food?
If the fridge shuts down due to the error, temperatures will rise. Food in the fridge can become unsafe after 4 hours above 40°F (4°C). Monitor internal temperature with a separate thermometer if the fridge has been off for an extended time.
