45/5 Capacitor

This is the exact style of dual run capacitor I needed—45/5—because it powers both the compressor (HERM) and the fan. If your old one is labeled 45/5 with a similar tolerance, this is the simple swap that can save you a $300–$400 service call.

  • -Only works if your unit matches 45/5 specs
  • -You still need to follow safety steps and discharge the old capacitor
