How to Add Freon/Refrigerant to a Refrigerator With a Piercing Valve - Easy DIY Repair

This video shows the complete DIY repair process for fixing a refrigerant leak in a mini fridge by adding the necessary refrigerant charge. I demonstrate the full R-134a charging procedure and detail how to install the piercing valve (also known as a bullet valve or line tap) safely onto the sealed system. The recharge method shown here is nearly identical for other refrigerants like R600a (common in newer systems). This easy DIY fix applies to various small appliances, including wine coolers, chest freezers, portable ice makers, and water coolers. Learn how to gauge pressure and safely top-off your appliance to get it cooling again! IMPORTANT DIY DISCLAIMER: Before attempting this refrigerant top-off or sealed system repair, you must perform full diagnostics. This DIY project assumes you have correctly identified a refrigerant loss or micro-leak as the sole issue.
