Our take on the Rheem 43-TL45053-R Capacitor 45/5/370 Dual Roun

The Rheem 43-TL45053-R is a dual run capacitor for HVAC motors: 45 µF for the compressor and 5 µF for the condenser fan, rated at 370 V. One can replaces two separate capacitors, which is why dual runs are the standard part in most residential condensing units. It is a service part, not an upgrade: buy it to restore a motor that has failed, and match the microfarad and voltage ratings to the old can exactly. Generic dual-run capacitors with the same ratings do the same job; the Rheem name matters mainly for exact-fit replacement in Rheem and Ruud equipment.

Pros
  • Two capacitances in one can, so one part serves compressor and fan motor
  • Standard 45/5 µF, 370 V ratings fit many residential condensing units
  • Round dual-run case fits the usual mounting strap and terminal layout
  • Rheem part number makes exact-match ordering simple for Rheem and Ruud systems
Cons
  • No higher voltage margin than 370 V; 440 V cans last longer on marginal power
  • A failed capacitor is a symptom; the underlying cause still needs checking
  • Wrong microfarad rating can damage the compressor motor
  • No discharge resistor or mounting hardware included in most cases

Questions and answers

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.
Where is the Rheem 43-TL45053-R Capacitor 45/5/370 Dual Roun cheapest?
At PartsHouse, for $5.93, 50% under what the other stores charge, as of our latest check.
