Unresolved Extruder wont release filament after heating up

Ok I took a break from printing things for awhile as I finished a Fallout clock for my daughter. It was cool and I was happy and she loved it. The next object I tried printing was a holder for my go pro, but here is where problem started. This happened a month ago so I been real busy with work but anyhoo I tried to see if this problem still continued. It did, so here is the problem I was feelding my filament through the top into the hole after this heated up to 180, and I am using PLA, havent had the balls to use ABS but im happy with the turnouts with PLA so far. Anyways, as I start to print Im seeing some filament oozing and I clean off the head, as it starts to print, it will not release any filament. Thinking I have a clog somewhere or inside it not sure.. but I reviewed Anthony's video on how to determine if its a clog or a stuck issue or something. I havent dived into finding out just yet. So a few weeks ago I fired the machine up again tried to see if its going to behave and still have the same issue but still it does ooz out some filament prior to print but will not print out anything. So here I am waiting for my weekend to come across which wont be too long here YAY me! Im wondering if I have to replace head if heads bad or tear apart in which i have very little confidence in tearing apart and end up with a 700 dollar paper weight...

 

Ok thanks for replying it's a robo 3D plus I usually heat it up to 210 to run. I load it around 185 as it says on printer. Anymore info needed lemme know. Thank you

 

Havent used a oiler yet im sure that will add ease to it or help this issue from happening again.

 

Thanks guys I will look into this as well as seeing if this fixes. Much appreciated !
