Thermador Refrigerator Error Code LOWPOWER

The LOWPOWER code means the refrigerator has detected that the incoming supply voltage is below the minimum required for operation, which is 85V in the US or 165V in EU installations. The appliance suspends all cooling functions to protect internal components from damage caused by low-voltage conditions. The code will clear and normal operation will resume once the supply voltage returns to an acceptable level.

The error code itself indicates the refrigerator has safely shut down to avoid damage, so the appliance is protecting itself correctly. However, the underlying cause of the low voltage, particularly a loose neutral connection in the electrical panel, can be a serious electrical hazard. If you suspect a wiring or panel issue, have a licensed electrician inspect your home's electrical system before using the outlet again.

The cost depends entirely on the cause of the low voltage condition. If the issue is a utility brownout, there is no cost to you. Replacing a faulty wall outlet typically costs between $75 and $200 including labor. If the problem requires electrical panel work or circuit upgrades, costs can range from $150 to $800 or more depending on the scope of the repair. No parts within the refrigerator itself are typically required for this error.

Start by measuring the voltage at the wall outlet using a multimeter to confirm that low voltage is actually present. If the voltage is low, identify whether the cause is a utility brownout, an overloaded circuit, or a wiring issue in your home. Make sure the refrigerator is plugged directly into a grounded outlet rather than an extension cord, and consider having a licensed electrician inspect your panel and wiring if the problem persists.

Resetting the refrigerator will not resolve the LOWPOWER code if the supply voltage is still below the required threshold. The appliance will continue to display the error and remain inactive until voltage rises above 85V (US) or 165V (EU). Once the voltage issue is corrected at the source, the refrigerator should resume normal operation without requiring a manual reset.
