GE Condensing Dryer stops before completing a cycle

Model #: DCCH480EKWW

circa 2012

On the rare occasion the dryer will complete a cycle. Most of the time it stops a few seconds after I push the start button, though sometimes it will run for 5 mins or so before stopping. Switching between sensor dry, time dry or air fluff doesn't make a difference. When it stops it makes a generic beep and flashes the time remaining on the digital display - no error code or anything.

Does anyone have an idea on what might be going on?

Thanks in advance!
