Yoder 640 heating up but not maintaining temp

I just started having an issue with my 640. I go through the normal process of turning on the yoder however yesterday it started to show downward bars before it got to temp, almost like it is sensing it is over the set limit. Anyway it will go to originalist point then show downward dashes and goes to 100 or so degrees. I have tried shutting off, unplugging waiting and trying again. No luck.

Any suggestions?
