Is your GF too cold?

Take the crumb tray out, and into a warm/hot place. I leaned mine against a coffee table in front of a fire ! Got it nice and warm, then went back into the garage (42F) and replaced it inside, waving my hands about to stir up the air a bit. Went back to the house, loaded a design, and off it went, happily calibrating.
