Extruder temperature rises unboundedly high
Time to time heating of the extruder becomes uncontrollable. I'm using ramps 1.4 setup with repetier firmware 0.92.
The tasks are generated with Slic3r and the problem appears during printing either via Repetier-host 1.62 or directly from the sd card
is it a hardware issue or should I play with PID control?![image](https://yadi.sk/i/bAI29P0fudcqc)

Usually the problem appears when some time has passed. In case the the temperature plot i'm trying to attach isn't available here is a brief story: for some time everything is ok: the temperature stays around target temperature +/-2deg, then it suddenly begins to grow, and pwm bars seems to respond properly by decaying to zero, but the extruder keeps heating up anyways
Have you heard some similar stories?
