Using this Westinghouse fridge control module is straightforward. First, unplug your fridge from the power source to ensure safety. Then, carefully remove the old control module. It might be held in place with screws or clips. Take note of how the wires are connected before disconnecting them. Next, connect the wires to the new module in the same way. Once everything is connected, put the new module back in place and secure it. Finally, plug your fridge back in. As for maintenance, keep the area around the module clean and free from dust. Regularly check the connections to make sure they're secure. Remember, if your fridge has other problems, like a faulty defrost element or compressor, it could cause the module to fail. So, if you experience any issues, check these parts too. There's no warranty for damage caused by external things, so protect the module from physical damage and extreme conditions.
