- What does 45+10 µF mean on this capacitor?
- It is a dual capacitor: one section is 45 µF for the compressor and the other is 10 µF for the fan motor. Both share one case and one common terminal.
- Can I use it to replace a 45/5 µF capacitor?
- Only if the fan section truly needs 10 µF. The compressor section must match at 45 µF, and the fan section should match the motor's rating; substituting a different value can overheat or stall the fan motor.
- Does the 440/370V rating matter?
- It is the maximum voltage the capacitor is rated for. A 440V rating covers 370V systems, so it works in either, but never install one rated below your system's voltage.
- How do I wire the three terminals?
- The terminals are typically labeled for compressor (HERM), fan (FAN) and common (C). Match the original capacitor's labeling and disconnect power before swapping.
- Is this capacitor safe around older refrigerants?
- It is non-PCB, so it avoids the hazardous dielectric found in legacy capacitors. It still holds a charge after power-off, so discharge it before handling.
- What is covered by the warranty?
- MARS offers a five-year limited warranty. Keep the receipt and confirm the part number, since coverage terms are set by the manufacturer.
