Replaces / Cross-Reference Part Numbers

  • Replaces any round or oval dual run capacitor with matching 70/5 MFD and 370V or 440V specifications. A 440V capacitor can be used to replace a 370V capacitor.
  • Common part number formats include: CBB65, P291-7054R, USA2236, C3705R, C4705R, TRCD705, and CAP05070.
  • Compatible replacement for capacitors from brands such as Genteq, Packard, Titan, and TEMCo.

Compatibility & Fitment

  • Used in air conditioning units, heat pumps, condensing units, and other HVAC systems to run a compressor motor and a fan motor simultaneously.
  • Physical dimensions must be verified for fitment in the existing mounting bracket.
    • Diameter: Approx. 2.36 in (60 mm)
    • Case Height: Approx. 5.4 in (137 mm)
  • The dual voltage rating allows for use in both 370 VAC and 440 VAC applications.

When to Replace

  • Compressor or fan motor hums but fails to start.
  • AC unit requires a manual "push start" to get the fan spinning.
  • Air conditioner blows warm air.
  • Visible damage to the capacitor, such as a bulging top, swelling, or fluid leakage.
  • Capacitance measurement is outside the rated ¬±5% tolerance when tested with a multimeter.

Installation Tips

  • WARNING: Disconnect all electrical power to the HVAC unit before handling or replacing the capacitor.
  • Safely discharge the existing capacitor by carefully shorting across the terminals with an insulated screwdriver.
  • Before disconnecting, note the wire colors and their corresponding terminals ("C", "HERM", "FAN").
  • Connect the run wire from the compressor to the "HERM" terminal.
  • Connect the run wire from the fan motor to the "FAN" terminal.
  • Connect the common wire from the contactor to the "C" terminal.
  • Ensure all connections are secure before restoring power.

Wonderful
Size: 9 Inch, Color: Red
Just bought my second one for my German shepherd. 1st one I bought a year ago. She managed to pop it within a few days. She still was able to play with it by grabbing ahold of the straps. Takes it everywhere. We call it her tether ball. Should've seen her when we got the new one out of the box. Hasn't left it alone since.

Thankfully I bought 2. One of the pumps broke as I was trying to blow up. That is the reason i did not give then 5 stats. This is a great toy for my puppy. Keeps him entertained and is pretty sturdy.

Great for dog self play
Size: 6 Inch, Color: Red, Size: 6 Inch, Color: Red
So much fun for my puppy. Easy to grab and throw for him to play alone. Durable for a medium dog. This is his favorite toy. I also bought one for my friends cattle dog puppy who went bonkers with it. Yet her dog liked to chew the tags off. So I wouldn’t recommend for chewers.

Fun to fetch
Size: 5 Inch, Color: Red, Size: 5 Inch, Color: Red
Perfect size for my 1 yr old Cavapoo that is ball obsessed. This ball is fun to toss around in the yard to exercise and wear out my energetic boy. Perfect for after my work day when I don’t have the energy to match his energy level. He gets to run and chase and I can enjoy his playtime too. Overall the ball is durable and I have confidence it will last for a very long time. We have 2 sizes, small and medium, for my 30 pound athletic pup. He enjoys both equally.

Dog loves them
Size: 6 Inch, Color: Independence Day
My dog loved the first ball I got her, so I got her a second one. Both hhavr been very durable (she likes to puncture things with her teeth). I left each ball slightly deflated, so they were still firm, but she could bite them without issues. She has not punctured either ball yet. I did have to watch her because she started trying to chew the tabs off because she was bored. She has not chewed one off, just started thinking about it, and did a tiny bit of damage to one tab. She loves these balls. We have played tug of wat with them too, so yhe tabs are sturdy, and so is the ball. The dog did not care what collar she got, so I grabbed the least expensive one, and the 6 inch. She is a medium sized dog with razor teeth, and these work great.
