HI there, I’ve called customer service and tried to order a replacement remote for my fan. The remote does not have the learn button, just the 4 dip switches. IT’s an oval 3 speed with the light on-off design. They said that without the model number they can’t order the replacement remote. I don’t have the box or the manual and the fan has a model number on a sticker but it’s not correct, says that customer service agent. Any ideas?
