Fault Identification Codes: Two quick flashes, pause for one second example 1. 1-second steady light, 1-second pause (even slow flash) 2. Light off, Compressor operating normally 3. Two quick flashes, pause for one second: Overcurrent condition, current exceeds 50A (e.g., excessive system pressure, compressor motor failure leading to high current) Troubleshooting 1. If the compressor shuts down within 20 seconds of startup, check if the power line is properly connected, if the fuse screws are properly tightened, and if there is oxidation at the battery terminals. Use sandpaper to clean and reconnect. A 20-second shutdown is generally a power issue, especially for units used over a year, where terminal corrosion may occur. 2. If the shutdown occurs after 2 to 3 minutes, it is generally due to high system pressure (e.g., overfilled refrigerant, system blockage, condenser dust accumulation causing poor heat dissipation, or electronic fan malfunction). 3. Test with power-saving or energy-saving modes, which use less current and typically avoid over current protection. If these modes function without issue, the controller and internal unit are likely fine, and other causes should be checked. 4. Three quick flashes, pause for one second: Locked rotor protection： Troubleshooting: Generally due to mechanical failure of the compressor or poor power connection causing insufficient current to the controller. 5. Four quick flashes, pause for one second: Under voltage protection： Troubleshooting:1. Check if the battery is genuinely under voltage and needs charging；2. If under voltage occurs at startup, check for poor power connections；3. Adjust the panel under voltage value if the wiring is too long (controller under voltage value is 19.5V). 6. Six quick flashes, pause for one second: Electronic fan fault： Troubleshooting: Check if the electronic fan is working or if there is any disconnection or short circuit in the fan wiring. 7. Seven quick flashes, pause for one second: Motor phase loss: Troubleshooting: Check if the compressor motor is properly connected or burned out. 8. Eight quick flashes, pause for one second: Compressor temperature protection: Troubleshooting: Check if the compressor is overheating or if the temperature sensor is properly connected. Short-circuit the temperature sensor for testing. 9. Nine quick flashes, pause for one second: System pressure switch protection: Troubleshooting: Check if the system pressure is too high or directly short-circuit the pressure switch for testing. Contrast 12V Auto Compressor 24V Auto Compressor Review: Excellent 12 volt Electric AC Compressor - I am very happy with this 12-volt ac compressor. I installed in my 69 Corvette that has an LS2 swap and Vintage Air. Many reviewers had issues with wiring the unit, I had no issues, it was easy to wire the instructions were very clear and easy to wire, the trigger wire from my vintage air controls the on off of the compressor and the condensor fan wires supplied with the compressor connected direct to my condensor fan relay, I also like the fact when the AC is turned off the condensor fan runs for an additional 20 seconds. Vent temp is in the 40s with ambient temp in the high 80s. Review: Works great - Perfect for my Chinese brand excavator ## Features - Electric compressor with separable controller for 12 v - The compressor contains 120 ml poe oil 68 inside already. If there is other pag oil left in your cooling system, we advise you drain the oil that comes with the compressor and still use the same oil as before, or clean the cooling system before installing the compressor, in order to ensure the normal use of the compressor. - Control Type:3 Gear - Refrigerant:R134a - Order from ACTECMAX, we can provide 1 year free worry warranty, ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CQYJ6PSS | | Additional Features | Low Noise Operation | | Best Sellers Rank | #168,462 in Automotive ( See Top 100 in Automotive ) #385 in Automotive Replacement Air Conditioning Compressors | | Brand | ACTECMAX | | Brand Name | ACTECMAX | | Capacity | 20 Milliliters | | Color | Electric | | Customer Reviews | 3.8 out of 5 stars 9 Reviews | | Included Components | Electric Compressor | | Item Type Name | AUTO AC COMPRESSOR | | Manufacturer | ACTECmax | | Manufacturer Part Number | AC.100.3851 | | Manufacturer Warranty Description | 1 year | | Maximum Power | 120 Watts | | Model Name | Electric Compressor | | Model Number | AC.100.3851 | | Power Source | Corded Electric | | Recommended Uses For Product | Automotive Air Conditioning | | Special Feature | Low Noise Operation | | Style | Automotive Air Conditioning Compressor | | Tank Volume | 120 Milliliters | | Unit Count | 1.0 Count | | Voltage | 12 Volts | ## Product Details - **Brand:** ACTECMAX - **Power Source:** Corded Electric - **Recommended Uses For Product:** Automotive Air Conditioning - **Special Feature:** Low Noise Operation - **Voltage:** 12 Volts ## Images ![Universal AC Electric Compressor 20cc/r Air Conditioner Compressor for 12V Auto Compressor for R134a - Image 1](https://m.media-amazon.com/images/I/711NQ2Jz4oL.jpg) ![Universal AC Electric Compressor 20cc/r Air Conditioner Compressor for 12V Auto Compressor for R134a - Image 2](https://m.media-amazon.com/images/I/6165EgiYn1L.jpg) ![Universal AC Electric Compressor 20cc/r Air Conditioner Compressor for 12V Auto Compressor for R134a - Image 3](https://m.media-amazon.com/images/I/61X4n39GZlL.jpg) ![Universal AC Electric Compressor 20cc/r Air Conditioner Compressor for 12V Auto Compressor for R134a - Image 4](https://m.media-amazon.com/images/I/61bAwShmuoL.jpg) ![Universal AC Electric Compressor 20cc/r Air Conditioner Compressor for 12V Auto Compressor for R134a - Image 5](https://m.media-amazon.com/images/I/61mRKW3v2tL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent 12 volt Electric AC Compressor *by J***Y on May 8, 2025* I am very happy with this 12-volt ac compressor.
