Abstract

Error code 52 on your Carrier HVAC system means the compressor protector (an internal overload switch) has tripped. This usually happens when the compressor overheats or draws too much current. It's a safety feature, but it can also indicate a serious underlying issue like a failing compressor or electrical problem.
