Same. Replaced the automatic defrost heating element once. Which had the side effect of me learning of ways to vastly improve its efficiency, which may well be the biggest energy waster on these old fridges.

edit - almost forgot the "always on" heating element to prevent condensation in the ice dispenser chute, which also caused yellowing of the plastic (replaced and heater wires cut) until it looked like the house was inhabited by chainsmokers. These older fridges definitely weren't doing themselves any favors from an efficiency standpoint.
