We recently moved into a house that has an old ceiling fan controlled by a remote. The remote controls the fan as long as two wall switches are turned on (one for the light and one for the fan). The remote worked great for several weeks then suddenly stopped being able to control the fan, but the light still responds to the remote. This happened from one day to the next with no changes in any way to the fan or the remote. The batteries are obviously still good and the frequency switches haven’t been changed because the light still responds. But the fan is stuck on the highest level and won’t respond to the remote. Any ideas?
Are there two entrances into this room? The fan and light might be controlled by 3-way switches at each entrance. Since you recently moved in, perhaps someone flipped the other switch, not knowing what it was. Check for unknown switches in the vicinity and see of they affect the light and/or the fan.
