This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

A shoulder screw that secures appliance components and provides a precise pivot or spacer point. Replaces a missing or worn screw to restore alignment, reduce rattling, and keep panels and assemblies securely in place. What it does:

• Provides a fixed-diameter shoulder for pivots, spacers, or mounting points in assemblies.
• Holds panels and moving components at the correct distance to prevent binding or friction.
• A missing or worn shoulder screw can cause misalignment, rattling, or loose parts during operation.
• Used where a smooth-bearing surface and controlled clearance are required between parts.

• Disconnect power to the appliance (unplug or shut off breaker) before servicing.
• Handle small fasteners carefully to avoid dropping into assemblies; magnetic pickup tools can help.
• Start threads by hand to avoid cross-threading; tighten snugly but avoid overtightening.

This thermostat is the temperature control switch that helps regulate your appliance's internal temperature for proper operation and food safety. It replaces a failed or faulty control to restore consistent cooling performance. What it does:

• Senses interior temperature and cycles the compressor or heating element to maintain set temperature
• Stops cooling or heating when the thermostat fails open, or causes overcooling when it fails closed
• Commonly replaced for inconsistent temperatures or an appliance that runs constantly
• Works as the user-controlled temperature regulator in the appliance's control system

• Disconnect power before starting any repair to reduce shock risk
• Handle mounting hardware and wiring carefully; note wire locations before removal
• Test operation after install by setting temperature and confirming normal cycling
