What to do if my Tektino Service Equipment shows high pressure alarm 004?
- J
  jasoncruzAug 16, 2025
  If your Tektino Service Equipment displays alarm 004, but the gas cylinder gauge doesn't indicate excessive pressure, the issue might stem from a disconnected high-pressure switch plug from the PCA socket. Ensure the high-pressure switch plug is securely fastened. Another potential cause is a blockage in the pipeline connecting the compressor exit. In this case, replace the compressor exit side hoses.

Why is my Tektino Service Equipment not charging properly?
- A
  Anthony HowardAug 18, 2025
  If your Tektino Service Equipment isn't charging or is charging very slowly, there are a few potential reasons: * The equipment may not have enough refrigerant. Add refrigerant until it reaches 5kg. * The system might have pressure. Run the recovery function first to relieve the pressure. * The charge solenoid may not be working. Check solenoid No. 5.

  If your Tektino Service Equipment shows alarm 005 while the auto A/C has refrigerant, the low-pressure switch plug may be disconnected from the PCA socket. Make sure to fasten the low-pressure switch plug securely. If you're using RCC-6A, the hand valves might be closed. Open the RCC-6A HP/LP hand valves.

Why does recovery not stop on my Tektino Service Equipment?
- R
  rbarberAug 25, 2025
  If the recovery process on your Tektino Service Equipment doesn't stop, it could be due to a leakage in the automotive A/C or the equipment pipeline. Perform a leakage test, referring to the service manual for machine leakage test procedures. Another reason could be a malfunctioning compressor, which would require replacement. Note that longer recovery times are normal in winter.

What causes no change in recovery volume in Tektino Service Equipment?
- C
  Caitlin HesterAug 27, 2025
  If there's no change in the recovery volume on your Tektino Service Equipment, several factors could be at play: * There might be no refrigerant in the A/C. Stop the recovery process. * The support screw of the gas cylinder load cell might not be loosened. Unscrew the support screw at the bottom of the weight sensor. * The gas cylinder load cell may not be working, or there could be a PCA failure. Calibrate the gas cylinder load cell, replace the load cell, or replace the PCA. * If you are using RCC-6A, the hand valves may not be open. Open the RCC-6A HP/LP hand valves.

  If your Tektino Service Equipment has no display, the possible causes are: 1. A blown fuse (either in the power cable connection box or on the PCA). Replace the fuses. 2. A burnt PCA. Replace the PCA. 3. A loose power cable. Ensure the power cable is securely connected. 4. A malfunctioning LCD. Replace the LCD.

Why is my Tektino Service Equipment vacuum pump injecting oil?
- A
  ashleystoneSep 2, 2025
  If your Tektino Service Equipment's vacuum pump is injecting oil, it could be due to: * Excessive oil volume. Discharge oil to the central line. * Entrance pressure being too high. Run the Recovery function first.

- K
  Katelyn EspinozaSep 5, 2025
  If the vacuum degree is low in your Tektino Service Equipment, consider the following: 1. Insufficient vacuum pump oil. Add oil to the central line. 2. Pump oil emulsion or dirty oil. Replace the oil with new oil. 3. Plugged pump oil inlet. Clean the oil inlet. 4. Leakage in the pump connection. Check the connection. 5. Worn-out components. Replace the pump.

What causes vacuum pump to be pressurized during Tektino Service Equipment recovery?
- R
  rmartinSep 8, 2025
  If, during recovery, the vacuum pump of your Tektino Service Equipment is pressurized and there's too much oil in it after a period, it's likely that the contact between solenoid valve No. 4 and the valve base isn't well sealed. Remove solenoid No. 4 from the valve base and clean both the solenoid valve and the valve base.

Why is there suction in the old oil bottle during vacuum in Tektino Service Equipment?
- C
  Cheryl NicholsonSep 12, 2025
  If, during vacuum operation, there is suction in the old oil bottle of your Tektino Service Equipment, it indicates that the contact between solenoid valve No. 2 and the valve base is not well sealed. The solution is to remove solenoid No. 2 from the valve base and clean both the solenoid valve and the valve base.
