When a water regulating valve for a condenser is jammed and becomes too restrictive, it limits the flow of water through the condenser coils. As a result, the condenser cannot efficiently dissipate heat from the refrigerant. This leads to a higher discharge pressure in the system, which subsequently increases the workload on the compressor.

With the compressor working harder to pump refrigerant against the elevated pressures, it draws more current, causing the amperage to rise. This increase in compressor amperage indicates that the compressor is operating under stress due to the inadequate heat exchange facilitated by the jammed valve. Understanding this relationship between the flow through the condenser and the compressor's electrical consumption is crucial for diagnosing issues in residential air conditioning systems.
