WP484322 Whirlpool Air Conditioner/ Dehumidifier Tube Restrictor

Imagine your air conditioner or dehumidifier quietly humming along, keeping your indoor air comfortable and cool � but unbeknownst to you, one tiny internal part is doing a lot of heavy lifting. That’s where the WP484322 tube restrictor comes in. This modest but crucial component regulates the flow of refrigerant inside your system, helping maintain the right pressure and temperature balance. Without it functioning properly, your unit might struggle � becoming inefficient, freezing up, or failing to cool effectively. So even though it’s not glamorous, the restrictor plays a key behind-the-scenes role in the “plumbing� of your cooling system.<br><br> <B>Product Highlights & Key Details:</b><br> <B>Part name & number:</b> Whirlpool / Dehumidifier Tube Restrictor � WP484322.<br> <B>Compatibility & brands:</b> While made for Whirlpool, this part also fits various affiliated brands (Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, Admiral). Whirlpool also manufactures parts for Sears-Kenmore and IKEA.<br> <B>Replaces many alternate part numbers:</b> This WP484322 is a substitute for several competitor part numbers, like 1160538, 1168677, 1182809, 485464, 485788, 993205, and many more.<br><br> <B>How It Works / Why It Matters:</b><br> A tube restrictor is like a narrow gateway in the refrigerant path. It limits how much refrigerant vapor or liquid can pass through at a time, which helps maintain the proper pressure difference between different parts of the system (for example between the evaporator coil and condenser). If that opening is too wide or blocked, the balance gets disrupted: you might get poor cooling, ice buildup, or even system damage. Because this WP484322 is specifically designed for compatible Whirlpool (and allied brand) units, it ensures the right fit and performance. Using the correct restrictor also helps your system run more efficiently and reliably.<br><br> Though small and often overlooked, the WP484322 tube restrictor plays a vital role in keeping your air conditioner or dehumidifier running smoothly. When it’s functioning right, you’ll enjoy better cooling efficiency, fewer breakdowns, and longer component life. If your system shows signs of struggle (ice forming, inconsistent cooling, etc.), checking this restrictor is a smart move.
