Replaces / Cross-Reference Part Numbers
This capacitor replaces any round or oval dual run capacitor with matching 45+5 uF capacitance and 370V or 440V specifications. It serves as a universal replacement for a wide range of part numbers from various manufacturers.
Compatibility & Fitment
Designed for heavy-duty, continuous use in HVAC systems such as central air conditioners and heat pumps. This dual run capacitor powers a compressor motor (HERM terminal) and a fan motor (FAN terminal) simultaneously from a single common line (C terminal). It is compatible with units requiring the specified capacitance and voltage.
When to Replace
A failing capacitor can cause damage to motors. Consider replacement if you observe the following symptoms:
- Compressor or fan motor struggles or fails to start.
- AC unit hums but does not activate.
- Fan spins slowly or not at all.
- Visible signs of damage, such as a bulging or leaking capacitor case.
- Measured capacitance is outside the rated tolerance (e.g., not within ±6% of 45/5 uF).
Installation Tips
- Warning: Capacitors can store a lethal electrical charge even when power is off.
- Disconnect all electrical power to the HVAC unit at the main breaker panel before proceeding.
- Safely discharge the old capacitor by carefully shorting across the terminals with an insulated-handle screwdriver.
- Confirm the uF and VAC ratings of the replacement match the original component.
- Note the wire placement on the C, FAN, and HERM terminals before disconnecting.
- Ensure all new connections are secure. Professional installation by a qualified technician is recommended.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard
White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it.
Orange is easy to see in the grass at day
They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too
The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

Love this set!!!
Size: Medium (2.5"), Style: Fetch Pack 1
I was trying to figure out which of the many different balls this company offers, and I was getting frustrated but then i was SOOOO happy to see they had multiple sets that had multiple of the different balls they offer!! I bought this set and the other set they offer, but this one was my favorite and I think my dogs too! The orange ball works great and bounces just high enough that it doesn’t clear our patio wall, but enough for him to go and jump up to retrieve. But the glow in the dark ball is his favorite! Both me and my pomsky were blown away how we brought the glow in the dark ball outside just as the sun was going down, and when we brought it back inside it was BRIGHT AND GLOWY!!! Even with the sun going down and not much light left!! He loves to play with it in the house after it’s all glowy from the sun. Sometimes we even glow it up under a light inside the house if it’s dark outside, and he will play with it outside in the dark haha he loves it!!! And I think it’s pretty cool too!! All of the balls this company overs are VERY durable! We realized early on that we cannot give our dog regular tennis balls cuz his favorite thing to do is tear the outside fabric off!! So we were trying to figure out what company has the best balls for dogs so they can’t sit there and try to pry them apart, and we found this company!! We have already bought from them about 3 times and all of their balls are durable and bounce how they say they will bounce!! They have the super bouncers and the glow in the dark one and the one with angles that will bounce in different directions and the ones you can throw REALLYY far! Overall, all the balls from this company are very durable, bounce really good, and keep my dog occupied without allowing him to sit there and tear it apart!!! Which i love cuz I do not like when he stops playing with us to sit there and try to take off the fabric, cuz then he could swallow it! So always buy the balls from this company!!! They are the best and most durable!!!! Also plenty soft for your dogs mouth so they can chew on it a bit and it won’t hurt their teeth/gums!

Good sturdy balls
Size: Medium (2.5"), Style: Fetch Pack 2
My dogs love balls! Unfortunately, they tend to chew them up very quickly. My Belgium Malinois chews on this all the time, and it has held up pretty well. Good option for chewers

Fetch Perfection
Size: Medium (2.5"), Style: Fetch Pack 2
If you’re anything like me, fetch is the ultimate game with your furry companion. The Chuckit! Dog Fetch Ball Medley has taken our playtime to the next level with its variety and durability. This 3-pack of medium-sized, ultra-rugged balls is perfect for endless games of fetch without worrying about wear and tear.
I love how each ball has a unique texture and color, keeping my dog engaged and excited every time. The medium size is just right for energetic dogs, allowing for long throws and big leaps. Plus, the rugged design means these balls can withstand even the most enthusiastic chewers and rough play sessions, making them a great investment for active pets.
However, the vibrant colors can sometimes make them easy to lose in green grass or sandy beaches, but a good game of hide-and-seek with your dog is a small price to pay for such fantastic fetch balls. Additionally, while they’re durable, no ball is completely indestructible, so occasional replacements might be necessary for the most aggressive players.
Overall, the Chuckit! Dog Fetch Ball Medley is a must-have for any dog owner looking to enhance their playtime. They’re fun, durable, and keep both you and your dog entertained for hours. A solid 5-star rating for their quality and variety, with a tiny star lost to their occasionally elusive colors.
