- Will this replace my current run capacitor?
- Only if your old capacitor is also dual-section 45 + 7.5 MFD and rated 370 V or 440 V, and the can is round. Match the microfarad values and voltage exactly; a different value can damage the compressor or fan motor.
- What is the difference between 370 V and 440 V here?
- The capacitor is rated for both, so it can be used on either 370 V or 440 V systems. Using the higher-rated part on a 370 V system is fine.
- What does the internal safety switch do?
- It is designed to open when the capacitor fails so the failure does not take out other components such as the compressor or fan motor. It does not prevent the capacitor itself from failing.
- Is it hard to install?
- It is a direct swap for a matching capacitor: discharge the old one, note the wiring, unclamp, and reconnect. If you are not comfortable working with line voltage, have an HVAC technician do it.
- Does it come with mounting hardware?
- No. It is the capacitor only; reuse the existing clamp and wiring. Check that your unit uses a round clamp mount before buying.
- How long should it last?
- Run capacitors commonly last several years in hot condensing units, and the 5-year warranty covers defects. Heat and high line voltage shorten life, so expect shorter service in harsh conditions.
