    Why is my Leizig FCC825 system high pressure alarm going off?
    • A
      Ashlee YoderAug 10, 2025
      The high pressure alarm in your Leizig Temperature Controller system may be triggered by several issues. It could be due to dirt on the condenser, which requires cleaning. Another cause might be incondensable air in the system, suggesting you need to vacuumize and refill the refrigerant. A blocked condenser fan filter mesh, which requires cleaning, or a condenser fan that won't start, potentially needing a capacitor replacement, could also be the cause.

    What to do if my Leizig FCC825 Temperature Controller compressor is not working?

      If the compressor of your Leizig Temperature Controller isn't working, several factors could be responsible. It could be due to abnormal voltage, in which case you should adjust the capacity of the mains power supply, voltage, and output. Alternatively, a faulty contactor or thermostat malfunction could be the cause, suggesting you replace the contactor or replace the thermostat if disconnected, or adjust its accuracy if connected. Other potential causes include an overheat protector burnout (replace if disconnected), capacitor aging (replace the capacitor), or a program error on the control panel (replace it after cause clarification).

    Why does the air switch trip after Leizig FCC825 Temperature Controller AC startup?
    • J
      James JacksonAug 26, 2025
      The air switch tripping after your Leizig Temperature Controller AC starts up could be due to several reasons. It might be a breaker malfunction, suggesting the breaker's capacity should be 1.5 times the AC working current. Other potential causes include a compressor malfunction or system leakage, in both cases you should contact the manufacturer. Also, a blocked condenser fan filter mesh could be the cause, in this case clean the filter mesh.

    What to do if Leizig Temperature Controller compressor and fans are working but not cooling?
    • M
      Mark SimmonsSep 2, 2025
      If your Leizig Temperature Controller's compressor and fans are running but not cooling, it could be due to refrigerant leakage or a dirt blockage. For refrigerant leakage, test and mend the leakage, pressurize and vacuumize the system, and contact the manufacturer for commissioning after refrigerant refilling. If it's a dirt blockage, replace the filter dryer, pressurize and vacuumize the system, and contact the manufacturer for commissioning after refrigerant refilling.
