Daikin Mini Split Error Code E8: How to Fix It

Q: What is the most common cause of Daikin error code E8?

The most common cause is a failed run capacitor on the compressor. Testing and replacing it often resolves the issue.

Q: Can I reset a Daikin mini split to clear error E8?

Yes, you can try a hard reset: turn off the breaker for 30 minutes, then turn it back on. If the error returns, there is an underlying fault.

Q: Is it safe to replace a capacitor myself?

Only if you know how to safely discharge high-voltage capacitors and have experience working with live circuits. Otherwise, hire a professional.

Q: What does 'input overcurrent' mean in simple terms?

It means the outdoor unit is drawing more electrical current than normal, often due to a failing component like a compressor or capacitor.

Q: How much does it cost to fix error E8?

If it's just a capacitor, the part costs around $10-30. If the compressor needs replacing, expect $800-2000 including labor.

Abstract

Daikin error code E8 indicates an input overcurrent condition, meaning the outdoor unit's main power circuit is drawing too much current. This typically points to a faulty compressor, a bad capacitor, or a power supply problem. Here's how to troubleshoot and fix it safely.
