Using this Fisher & Paykel thermal cutout is straightforward. Just install it in your Fisher & Paykel built - in oven as a temperature limiter. It will work automatically, staying closed at normal room temperature and opening when the temperature hits 140 degrees Celsius. When handling the cutout, be gentle as it has a ceramic body which can break if dropped or banged. To maintain it, keep it clean and free from dust and debris. Regularly check the spade terminals to make sure they're securely connected. If you notice any signs of damage or if the cutout isn't working as expected, it's best to replace it with a new one.
