Low-Pressure Protection Switch for Heat Pump Mr.Silence MPXC170

The low-pressure protection switch for the Mr.Silence MPXC170 heat pump continuously monitors the refrigerant pressure on the suction side of the compressor. As soon as the pressure drops below a safe limit – for example due to a refrigerant leak or clogged filters – the switch automatically disconnects the compressor and prevents its destruction by running without sufficient lubrication.

This is an original spare part precisely calibrated for the MPXC170 model, whose correct function is a condition of warranty validity and safe operation of the entire heat pump. The precise calibration value corresponds to the design parameters of this model’s refrigeration circuit.

Replacing the switch is a relatively simple service task, but we recommend entrusting it to a certified refrigeration technician who will at the same time check the overall condition of the refrigeration circuit and top up the refrigerant if necessary. A functional protection switch extends the compressor’s service life and prevents costly repairs.
