Heat pump compressor starts then stops. Aug 29, 2025 · This reduces efficiency, causes uneven heating or cooling, leads to higher energy use, and increases wear on the compressor and electrical components. Troubleshooting a Heat Pump Compressor Starting and Then Stopping. Learn why this happens and what to do. 2 Faulty Capacitor. Fewer start-stop cycles reduce wear on the compressor and fan motor, which can translate to a longer equipment lifespan and fewer repair calls over the years. A malfunctioning compressor can cause inefficient operation, poor heating or cooling performance, and even complete system failure. The condenser intermittently (infrequent) makes a loud “thump” sound then briefly buzzes very loudly, which quiets to a lower-volume buzzing sound which continues (kind of sounds like the compressor locks up maybe). Another common cause of a heat pump compressor starting and then stopping is a faulty capacitor.
