What is a potential consequence of running a compressor if the pressure switch is defective?

Running a compressor with a defective pressure switch can lead to overheating and potentially damaging the system. The pressure switch serves a crucial role in monitoring and regulating the pressure within the compressor. When it functions correctly, it ensures that the compressor operates within safe pressure limits, turning the unit on and off as pressure thresholds are reached.

If the pressure switch is faulty, the compressor may not shut off when it should, leading to excessive pressure build-up. This continuous operation without proper regulation can result in overheating, as the compressor works harder than necessary, which increases the risk of mechanical failure, damage to internal components, and even total system breakdown. Thus, ensuring that the pressure switch functions correctly is vital for the efficient and safe operation of the compressor.
