Why is there no change in recovery volume in my Tektino RCC-6S-dual Refrigerator?
- C
  christopherstewartSep 8, 2025
  The recovery volume might remain unchanged because there's no refrigerant in the A/C, in which case you should stop the recovery. Also, make sure that the support screw of the gas cylinder load cell is loosened, referring to chapter 'Operation preparations'. A faulty gas cylinder load cell or PCA failure could also be responsible; try calibrating the gas cylinder load cell, or replacing the load cell, or changing the PCA.

Why does my Tektino Service Equipment vacuum pump inject oil?
- W

  If your Tektino Service Equipment's vacuum pump is injecting oil, it could be due to two reasons. First, the oil volume might be too high; in this case, discharge some oil to the proper level. Second, the entrance pressure might be too high; try running the Recovery function first.

How to fix low vacuum degree in Tektino Service Equipment?
- T
  Tiffany CarterAug 25, 2025
  A low vacuum degree in your Tektino Service Equipment can stem from several issues: * Insufficient vacuum pump oil: Add oil to the central line. * Pump oil emulsion or dirt: Replace with new oil. * Plugged pump oil inlet: Clean the oil inlet. * Leakage in the pump connection: Check the connection. * Worn-out components: Maintain the machine, paying special attention to o-rings, washers, and other sealing parts.

  Hannah WalkerAug 27, 2025
  If the recovery function on your Tektino Service Equipment doesn't stop, it could be due to a few reasons. There might be a leakage in the automotive A/C or equipment pipeline, so perform a leakage test, referencing the service manual for the machine leakage test. Alternatively, the compressor might not be working, requiring a replacement. Lastly, the pressure sensor could be faulty; try fastening the pressure sensor connection to the PCA or replacing the pressure sensor.

  If you notice no change in recovery volume with your Tektino Service Equipment, consider these potential causes. First, there might be no refrigerant in the A/C; if so, stop the recovery process. Second, the support screw of the gas cylinder load cell might not be loosened; unscrew the protection screw, as described in the “Operation preparations” chapter. Third, the gas cylinder load cell might not be working, or there could be a PCA failure; try calibrating the gas cylinder load cell, or replace the load cell or PCA.

Why is there suction in the old oil bottle during vacuum in my Tektino RCC-6S-dual?

  Maria ThomasSep 22, 2025
  If you notice suction in the old oil bottle during vacuum, the contact between solenoid valve #2 and the valve base may not be well sealed. Remove solenoid #2 from the valve base and clean both the solenoid valve and valve base.

Why is my Tektino RCC-6S-dual Refrigerator not charging or charging slowly?
- J
  jacksonwilliamSep 16, 2025
  If your Tektino Refrigerator is not charging or charging slowly, it could be due to insufficient refrigerant in the equipment. In this case, fill the equipment tank with more refrigerant. It may also be caused by a charge line problem. Check the charge line, including the tank red valve, tank red hose, solenoid #5, solenoid #9 (high side), solenoid #11 (long side), service hoses, and HP/LP quick couplers.

Why is there too much oil in the vacuum pump of my Tektino RCC-6S-dual?
- L

  If the vacuum pump is pressurized during recovery and there's too much oil in it, the contact between solenoid valve #8 and the valve base may not be well sealed. Remove solenoid #8 from the valve base and clean both the solenoid valve and valve base.

What to do if my Tektino RCC-6S-dual Refrigerator shows no display?
- C
  Christine CampbellSep 7, 2025
  If your Tektino Refrigerator display is blank, the fuse might be blown (either in the power cable connection box or on the PCA). Try changing the fuses. Alternatively, the PCA itself might be burnt, requiring replacement. A loose power cable could also be the culprit; ensure it's securely connected. If none of these solutions work, the LCD screen might be faulty and need replacement.
