This is a remote control for a YUASA fan, with four buttons. It uses AAA batteries. The fan itself has already been disposed of, so I don't know the model number. I don't specifically remember the remote being broken, but I can't confirm its functionality since I no longer have the fan. It seems to be receiving power. It is generally yellowed. - Brand: YUASA - Function: Remote Control - Number of Buttons: 4 - Battery Type: AAA - Model Number: AF5-13 Thank you for looking.
