Sub-Zero Making Popping or Cracking Noise
Making Popping or Cracking Noise is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Longer duty cycles at altitude
Less dense air means more running time for the same result, and the extra hours show up as bearing and mount noise earlier than the service interval assumes.
A failing fan motor
Evaporator or condenser fan bearings wear out gradually, producing noise well before the fan actually stops running.
Loose or vibrating panels
Cabinet panels or compressor mounts that have loosened over time can resonate against nearby surfaces.
