Hey there, if your LG refrigerator isn't cooling properly, this Mudder replacement kit might be exactly what you need to get things running smoothly again! This 2-piece set includes both the QP2-4.7 PTC starter relay (that's the 1-pin black plastic piece measuring 3.2 x 2.1 x 2.9 cm) AND the 6750C-0005P overload protector in white and black brass construction. Now, super important - before you order, double check your refrigerator model because this kit works with specific LG models like GMB228JQCA, LRFC22750TT, LRFC25750SB, and many others listed in the description. The PTC starter relay has 4.7 Ohm resistance and is that universal type used in lots of mini fridges and coolers. The overload protector is crucial because it prevents your compressor from overheating and getting damaged. Installation is pretty straightforward if you're comfortable with basic refrigerator repairs - just make sure you're replacing the exact same part numbers. These are direct replacement components that should restore cool air to your fridge without needing a costly service call. The materials are durable and rust-resistant, built to last through temperature changes and regular use. Whether you have a compact beverage cooler, deep freezer, wine refrigerator, or standard kitchen fridge, this combo kit covers the most common replacement needs. It's also compatible with part numbers like AP4439459, 1357963, and AH3529540 if you're cross-referencing. Having both pieces together means you can tackle the most likely culprits in one go rather than ordering separately. For the DIY repair person who doesn't want to spend hundreds on a service technician, this affordable kit could save your refrigerator and your wallet! Just remember to unplug the unit before starting any work and take photos as you disassemble to make reassembly easier.
