1) You have a clog. The ticking sound is the motor unable to extrude the filament.

2) Temperature is not high enough for the filament you are using. It's not melting so the motor will not extrude, which again makes the ticking sound.
Again the thermisters arent accurate, It might say 200 degrees on your printer, but the real temperature may be 180. You need to find the correct temps for each roll of filament you use.
When loading the filament, the extruder heats up to it's preset value. So increase the preset to increase the temp used for loading and unloading.
