I only found this out the other night because my fridge went dead silent for a long time. I thought it was borked, so I was peering deep into the freezer when I saw The Gates of Hell through the grate.

(Okay, so full disclosure, I had smoked some pot, but it totally looked like when Dana opened the fridge to Zuul before she was The Gatekeeper.) 😱😱😱

Anyways, turns out it was in defrost mode (which happens twice a day), and that involves some elements going orange or something. I know that’s vague-- I looked it up, but as I mentioned, I was high, so I only kinda remember, lol.

Edit:

The refrigerator activates a heating element located near the evaporator coil. This element warms the coils, causing any ice buildup to melt.
