Using this Westinghouse fridge control module is straightforward. First, make sure your fridge is unplugged for safety. Then, locate the old control module and carefully remove it. Install the new module in its place, following the same wiring setup. Once installed, plug the fridge back in. When using the fridge, be aware that if the module fails, it could be due to other issues in the appliance like a faulty defrost element or compressor. So, check these parts before assuming the module is the problem. For maintenance, keep the fridge clean and well - ventilated. If there are any signs of moisture around the module, dry it carefully. And remember, damage caused by external factors like power surges isn't covered by the warranty.
