Using this Westinghouse RJ212T no - frost thermostat is straightforward. First, make sure to connect the two main terminals correctly. The two in - line terminals are already connected, so you mainly need to focus on those two connections. And don't forget to attach the earth wires to the terminals on the metal body. When it comes to maintenance, keep an eye on the capillary tube. Avoid bending it sharply because it can cause damage to the thermostat. Also, if you notice any issues with the temperature control, it might be a sign that the thermostat needs to be checked.
