I have 2 lift master garage door openers that are producing errors when you hit the buttons to open 2 different doors. 1. I get error code 11 (sensor blocked or miswired)-there is nothing blocking door. 2. The other error on a separate door is error code 14 which is (sensor wiring intermittent connection error) and also then flashes the same error 11 as above example? How do I clear so they work properly?

If your garage door is up, and you break the beam (by walking through it, for example), you will get the "SENSOR WIRING INTERMITTENT CONNECTION ERROR CODE 1-4 SEE USER MANUAL". This is normal. Both of my Liftmaster 8550 openers do this. It's misleading, but this is what I've found to cause this error.
