Anova Precision Cooker - Crackling sound?

just wondering if anyone else’s unit is making a crackling sound as it heats up? I wonder if it’s part of the design or if somethings wrong with mine or if it won’t make a difference. I’m going to ask support as well just if no one else’s unit is making the sound.

Never mind. The crackling goes away once the hold temperature is reached - maybe it was just first start-up pains.

I have the crackling sound and it does not go away when heated up. There is nothing loose and the sound appears to come from inside the unit. Is it safe to use?

I m also experiencing a crackling sound. Started a couple days ago, have had no issues for a year until this.

Same here. After about 2 years of weekly use
