Topic: extruder temp reading 275 and clogged up nozzle

I have had this printer for about 5 months and when I was using some new filament the thing clogged. I took it apart and took out the piece stuck in the gears but there is still some inside the nozzle and I can't get it out after 3 hours of trying. When I place it back into the housing and reconnected it it gave me error 14 (Too hot, 275C) and when I disconnected the thermistor it gave a normal 10C so some how it's not working when plugged in. I placed my hand on the piece and it was room temperature. 

I need to get this fixed quick because I have some orders to fill in I make costume combs and misalliances stuff. I know my spelling is terrible by the way.

One of the wires on your thermistor is exposed and shorting to the brass heat block or both wires are exposed and shorting together. The later is most likely.

As a thermistor heats up its resistance drops and the machine reads this dtop as a rise in temp. If the wires are shorted together there will be nearly no resistance and the machine thinks it is way over temp.

I will test it with a multimeter.

You dont really need a multimeter. Just find the two wires that are touching. Worst case is the wires are touching in the hot end in the RTV. You will have to remove the RTV and fix the wires
