I imagine the asbestos is sealed inside? Don't chew the fridge.

Also old fridges inefficiency mostly comes from two things. The seals on the door, which you can replace, and 2nd the compressors are less efficient. Why are they less efficient? Mostly because they use thicker oil which causes more drag. However, that's partly why they last so long. Oil in modern compressors looks like water.
