The Malfunction trouble condition indicates a device is unable to properly communicate.

If a garage door opener is in malfunction: 

1. Open and close the door from the garage door opener’s wall control.
2. Request an update on the equipment status. 
3. Verify the garage door opener is within communication range of the router or panel. 
   • If using a LiftMaster garage door opener, verify the internet connection it is associated with is active. 
   • If using a Linear Z-Wave garage door opener, verify the device is within range of the Z-Wave network. 
4. If using a LiftMaster MyQ wall control, verify the MyQ wall control has power. 
5. If it is still in malfunction, contact your service provider.
