Using this Fisher & Paykel dryer control module is simple. First, make sure your dryer is unplugged. Then, find the old control module and carefully remove it. Replace it with this new one, connecting all the wires properly. When you're done, plug the dryer back in and test it. For maintenance, keep the module clean. You can use a dry cloth to wipe off any dust every few months. Also, make sure the dryer is in a well - ventilated area to prevent overheating. If you face any issues, don't try to fix it yourself. Just reach out to a professional technician.
