Try with a piece of cardboard.

@michellesintas1252 We've had so many problems with this fan, since we bought our home. The Sellers bought this fan brand new from H*me Dep*t back in 2023, and we got the receipts from them to prove it. Called the store and confirmed the purchase. They were controlling the fan from some app on their phone while they lived here, and when they moved, they uninstalled the app from their phone & from that point on, the fan did not work at all. We called Minka Aire, and they sent us a new receiver. Electrician came here, installed new receiver, and the fan/light were working. That was 3 mos ago, and we didn't use the fan since then, because it was storming here & cold. Now 3 mos later, it's warm here, we tried to use the fan, turned it on, and now the light won't go off. We called Minka Aire again, & they said to turn off the fan from the breaker, wait 1 min, turn the breaker back on, and then hold down the button on the remote that looks like a "little black square" for 30 seconds. They said THAT should reset it. Did it reset it? No. We called Minka Aire for the 3rd time, and now have an appt with our electrician to come here. We wanted a simple fan like we used to have, where we set the speed by the old-fashioned chain and the button on the wall was simply ON/OFF. Thing is, we had low ceilings when we had those fans. Here, we have vaulted ceilings and you need a fireman's ladder to get up there. Call us crazy, but we don't like these SMART devices that are all over the place and no, we're not really old people. We're in our late 30s.
