I can't provide specific instructions for your dryer without more information about its make and model. However, in general, the colors of wires in appliances like dryers can vary depending on the manufacturer and wiring standards. It's essential to refer to the dryer's user manual or the manufacturer's guidelines to ensure correct and safe installation.
In electrical systems, the green wire is typically the ground wire, which is intended to protect users from electrical shocks by providing a path for excess electricity to flow into the ground. The yellow wire, on the other hand, is not a standard color used for electrical wiring in household appliances, at least in North America.
To properly connect any wires to your dryer, I highly recommend consulting a qualified electrician or following the manufacturer's instructions. Electrical work can be hazardous if not done correctly, so it's best to seek professional help if you're unsure.
