    Why is my Wesper SLS 1202 Chiller making excessive noise?
    • M
      Mrs. Ellen BenitezAug 18, 2025
      Excessive noise in your Wesper Chiller can stem from several sources. Start by checking the clamping brackets of the lines to address potential vibration. If there is a whistler emitted by the thermostatic expansion valve, refill the chiller. Also, check the dehydrating filter. A noisy compressor may require replacement. Finally, ensure the compressor’s locknuts are tightened to address seized bearings.

      Rachel LeeAug 22, 2025
      If your Wesper Chiller activates the HP alarm and stops, first check the operation of the pressure switch, replacing it if defective. Ensure the delivery valve is fully open; if it's faulty, replace it. Drain the circuit to remove any substances with condensable gases. Also, check the condenser fan's cables and motor, repairing or replacing them if defective.

    Why is there ice on the suction line of my Wesper SLS 1202 Chiller?
    • C
      Christina NelsonAug 31, 2025
      Ice forming on the suction line of your Wesper Chiller could be due to a wrong calibration of overheating, so increase overheating. Also, check the charge.

    What causes low oil level in the compressor of Wesper Chiller?
    • R
      romerojohnSep 7, 2025
      A low oil level in the compressor of your Wesper Chiller can be caused by one or more gas or oil leaks in the circuit, so identify and remove leaks. Also, check the electric circuit and the resistor of the heater of the motor base, and replace defective components if there is an anomaly of the oil heater of the compressor’s base.

    Why is the liquid line of my Wesper Chiller frosting?
    • A
      Andrea Adkins PhDSep 12, 2025
      Frosting on the liquid line of your Wesper Chiller can occur if the valve of the liquid line is partially closed, so check that valves are open. Another cause could be a clogged liquid filter; in that case, replace the cartridge or the filter.

    What to do if my Wesper SLS 1202 Chiller compressors are not working?
    • W
      Wesley AveryNov 14, 2025
      If one or both compressors in your Wesper Chiller aren't working, several issues could be the cause. First, check the electric circuit for ground dispersions and short circuits and also check the fuses. If the HP pressure switch has intervened, reset it along with the control panel and restart the appliance, making sure to identify and resolve what triggered the pressure switch. Also, verify that the terminals are tightened and that there are no issues related to thermal overload. Other potential causes include wrong wiring, low line voltage, a short-circuit in the compressor’s motor, or a seized compressor. Check the wiring of check and safety devices. If the line voltage is too low and the problems regard the system, solve them; if they are caused by the distribution network, inform the ...
