What are the reasons for the BYD F3 air conditioning compressor not working?
3 Answers
BYD F3 air conditioning compressor not working reasons are insufficient refrigerant, relay failure, clutch coil failure. Insufficient refrigerant causes: When the refrigerant is insufficient, it will cause the air conditioning clutch to engage frequently, or even the compressor not to work. Air conditioning clutch relay failure causes: Observe whether the evaporator blower can operate, and the result is normal. This indicates that the main air conditioning relay, blower speed switch, etc. are all functioning properly. Electromagnetic clutch coil failure: Control circuit failure causes the compressor not to work. The power supply for the compressor electromagnetic clutch is provided in series through the air conditioning switch, temperature control switch, and pressure switch (separation, low pressure).
As a long-time owner of the BYD F3, I've encountered the issue of the air conditioning compressor not working several times. The most common causes are blown fuses or wiring faults, especially during summer when high temperatures make wires vulnerable to rodent damage, leading to interrupted current flow. It could also be due to insufficient refrigerant; when the system pressure drops too low, it automatically protects itself by preventing the compressor from starting. Another possibility is aging relays - a gentle tap can help determine if there's a clicking sound. My neighbor didn't repair it promptly last time and ended up with a completely ruined compressor, costing unnecessary extra money. I recommend getting it checked at an authorized repair shop as soon as possible to avoid missing out on summer cooling. By the way, regular cleaning of the air conditioning system can help prevent these issues.
Hey, regarding the BYD F3 air conditioning compressor failure, I'll share my DIY inspection steps. First, locate the fuse box under the hood and check if the AC fuse is blown—just replace it with a new one to test. Next, listen for the relay sound; you should hear a click when the compressor should be working. Then, use a multimeter to measure the voltage at the compressor plug—no power means there's a wiring open or short circuit issue. Low refrigerant is also common; insufficient high pressure can cause the compressor to stop. Finally, consider control switch or sensor failures, but don't dismantle the high-pressure pipe yourself—it's risky. Start with the easier checks to save money, but always prioritize safety.
