Recently my fan stays on even if I push the off button on my Versa Touch remote. If I take out the battery and leave it out for a while or use a spare battery it will turn off when pushing the off button on the versa. When the fan will not shut off it makes a weird sound like a cracking or humming sound. Normally this is not an issue and only makes this sound when it will not shutoff. Any ideas how to fix this issue. Fan: Casablanca S3 93045 Remote: Casablanca Versa Touch http://www.casablancafanrepair.com/...mmonRep/W42-43Wallcontrols/VToneOperation.pdf When we purchased the home we found a second Versa Touch remote that is not being used, are this interchangeable or matched with each unit. If not i may be able to set the dips on the spare to the same position as the used one and it make just work but do not want to damage anything on the fan receiver end. Thanks for any help on this.
