Polar Refrigerator Error Code Sr

Sr indicates that the main control board (power board) has detected an internal fault. It can appear in any operating mode on N7LX and N8LX models. The fault may be triggered by a wiring issue at the gas valve or by a problem within the board itself. Checking the gas valve wiring connections and performing a power cycle are the first recommended diagnostic steps.

Start by verifying that the gas valve wiring harness is fully plugged in and that all connector pins are clean and undamaged. After confirming the wiring, power the refrigerator off and then back on to reset the board. If the Sr code reappears, the main control board or the gas valve may need to be tested further and potentially replaced.

Repair costs depend on the root cause. If the fix is simply reseating a loose wiring connector, there may be no parts cost involved, though a service call fee typically ranges from $75 to $150. If the main control board requires replacement, parts and labor combined can range from $200 to $450 or more depending on parts availability and local labor rates.

A power cycle, turning the unit completely off and then back on, will clear the Sr code if the fault was caused by a transient event such as a voltage spike or temporary signal loss. However, if the underlying issue is a loose wire or a failed component, the code will return after the reset. Always check the gas valve wiring before and after the reset to determine whether the fault is recurring.

The Sr code signals an internal fault detected by the control board, which means the refrigerator may not be operating normally. Until the fault is resolved, the unit could have compromised cooling performance. It is advisable to address the error promptly and avoid storing perishable items until the problem has been diagnosed and corrected.
