How to Fix Error Code 67

  1. Turn Off Power to the HVAC System

    ⚠️ Always turn off power before servicing HVAC equipment to prevent electric shock or injury.

  2. Locate the Run Capacitor

  3. Discharge the Capacitor

    ⚠️ Capacitors can hold a lethal charge even with power off. Always discharge before handling.

  4. Remove and Test the Capacitor

  5. Replace the Degraded Capacitor

  6. Reassemble and Restore Power

When to Call a Professional

If you are uncomfortable working with electrical components, if the error persists after capacitor replacement, or if you suspect a failing compressor or fan motor, call a licensed HVAC technician.

Frequently Asked Questions

What does Carrier error code 67 mean?
Error code 67 indicates a degraded run capacitor in the outdoor unit. The capacitor is losing its ability to store and release energy, which can hinder motor startup and overall system performance.
Can I still use my Carrier AC with error code 67?
It's not recommended. A degraded capacitor can cause the compressor or fan motor to overheat, potentially leading to a complete breakdown. Replace it as soon as possible.
How much does it cost to fix Carrier error code 67?
A run capacitor costs about $10–$25. If you hire a professional, expect to pay $100–$200 for the service call and replacement.
Why does a run capacitor fail?
Capacitors degrade over time due to heat, age, and voltage fluctuations. High summer temperatures and frequent cycling accelerate failure.
Can I replace the capacitor myself?
Yes, if you have basic electrical knowledge and safety tools. Always discharge the capacitor and turn off power first. If unsure, hire a professional.
