Cooking temp higher than set temp


Issue: My precision oven is frequently cooking over the last two week above set temperature. (I’ve observed temps 5 - 20 degrees over what was set.)

Scenero(Just did it today, but I’ve been having this issue for 2 ish weeks):

Video Temp running high - YouTube

  • Tank Almost to the Max line
  • Sous Vide mode set to 131
  • Wait for it to warm up
  • The temp on the front is reading 142

A few days ago:

Tank is full to Max line

  • Sous Vide mode set to 135
  • Warmed up ok
  • Put Beef in (temp still ok)
  • Came back an hour later and it was cooking at 150

Any suggestions would be great! Thanks!
