- How do I know this capacitor fits my unit?
- Read the ratings on the old capacitor: it must show 45 µF and 5 µF at 370 V or higher, in a dual round case. Match the terminal layout and can size so it seats in the existing strap.
- Can I use a 440 V capacitor instead of this 370 V one?
- Yes. A higher voltage rating is safe and gives more margin against surges; the capacitance values must stay at 45 µF and 5 µF.
- Is this the same as the capacitor in my Rheem or Ruud condenser?
- Check the part number on your unit's label or the old can. The 43-TL45053-R is Rheem's number for a 45/5 µF, 370 V dual run, but Rheem has used other ratings across models and years.
- What happens if I install the wrong microfarad rating?
- The compressor or fan motor will run hot and can fail. Never substitute a different capacitance to make a part fit; use the rating printed on the original.
- Does it come with mounting hardware?
- Capacitors are normally sold as the can alone. Reuse the existing strap and terminals, and discharge the old capacitor before touching the terminals.
