Using this oven thermostat is quite straightforward. First, make sure your oven is turned off and unplugged to avoid any electrical hazards. Then, find the old thermostat in your oven and carefully remove it, taking note of how the wires are connected. Install the new thermostat in place of the old one, connecting the wires to the 6.4mm spade terminals. Ensure the mounting holes on the thermostat line up with the corresponding holes in the oven and secure it properly. When it comes to maintenance, keep the thermostat clean. You can use a soft, dry cloth to wipe it down occasionally. Avoid using any harsh chemicals or abrasive materials as they may damage the thermostat. Also, check the capillary tubes and probes regularly for any signs of damage. If you notice any issues, such as a broken capillary or a malfunctioning probe, it's best to replace the thermostat. Always remember to follow the manufacturer's instructions for your specific oven model when using and maintaining the thermostat.
