Whirlpool WPW10378255 Shut-off Arm Ice Maker Part

Product Description

The WHIRLPOOL WPW10378255 is a genuine OEM shut-off arm designed for use in refrigerator ice maker assemblies. The shut-off arm is a mechanical feeler component that detects ice level in the storage bin and signals the ice maker to stop production when the bin is full. When the arm is broken, bent, or missing, the ice maker may run continuously or fail to cycle correctly. This is an OEM-spec replacement part, manufactured to the same dimensions and material standards as the original factory component. Licensed appliance repair technicians and experienced DIYers install this part during routine ice maker service.

This shut-off arm is used in refrigerator models equipped with a traditional swing-arm ice maker unit. It is positioned inside the freezer compartment ice maker housing and pivots on a pin to rise as ice accumulates. When the bin reaches capacity, the arm trips the shutoff switch to pause ice production. This part is a direct OEM replacement intended to restore original ice maker cycling behavior without modification.

Installation Notes

Installation is typically performed by a licensed appliance repair technician or a knowledgeable DIYer. Before servicing the ice maker, disconnect power to the refrigerator at the wall outlet or circuit breaker and turn off the water supply line. The arm snaps or pins into the ice maker head assembly - inspect the pivot point and switch actuator for damage before reinstalling. Do not force the arm into position, as the pivot pin and switch tab can break under excess lateral pressure.
