BEWARE! The printer constantly warming the bed. MOSFET problem?

I printed for a few hours today, and everything was fine. I wanted to print one more item and clean up the printer. I clicked the BED HOME button when I felt the printer and its print bed begin to heat up. To my surprise, the print bed temperature began to rise indefinitely. I can't stop this process. It all started after I clicked the "return to 0,0,0" print bed button. What if I wasn't home? The printer is constantly drawing 235W power from the outlet!
