[amsat-bb] G5400 elevation issue

The display on the control box reads correct elevation, but on my digital display on the Easy Rotor Controller shows erratic elevation position. I have recalibrated it several times with no success. It won't read any elevation until it is around 20° give or take. It also seems to have become worse since our really cold temps set in. My best guess is the pot in the rotor, but not sure where to start in the process.

Thanks in advance
