Using this fan motor is quite simple. First, make sure your oven is unplugged or turned off at the breaker to avoid any electrical hazards. Then, locate the old fan motor in your oven. You can remove the old motor by unscrewing the mounting screws. Next, take your new fan motor and align it with the mounting holes in your oven. Use the included mounting screws to secure it in place. Connect the 4 x 6.4mm spade terminals to the appropriate electrical connections in your oven, and don't forget to connect the earthing terminal. Once everything is connected, plug your oven back in or turn on the breaker. Your oven should now work with the new fan motor. When it comes to maintenance, keep the motor clean. You can use a soft brush to gently remove any dust or debris from the motor and the fan blade. If you notice any strange noises or the motor isn't working as well as it should, turn off your oven and check the connections. Make sure to handle the motor carefully, and if you're unsure about anything, it's a good idea to consult a professional.
