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.

Excellent Product!!! Will purchase again!
Size: 2' x 3' (Natural), Color: Wolf Tipped
Instead of ordering a cover for reclining loveseats, I chose to drape one of these over the headrest on either end of our loveseat. Not only do they protect the leather, they also help to elevate our decor. The rugs were received in a very timely manner. They are super soft, & warming as we move into the winter months. We've had family & friends comment on how great they look. 2 of them have already ordered, & added them to their sofa/loveseat/recliner decor. Have an issue of them slipping, add some velcro in between the crook of the cushion & the back of the furniture piece. It doesn't show & will help to keep the rug in place; if your busy body.!

Perfect for sensory sensitive kids and for the pure beauty of it

After speaking over the phone with the seller, I was confident in this purchase for my SPD son. They do not use harsh chemicals or dyes in the process. It is from New Zealand and the only use in Vietnam is for shipping. My son hasn't been diagnosed yet for Autism but he is in the process. He is super sensitive to all things sensory and Amazon feedback isn't the place to give specific details on his condition but I will write that when he fist touched it- which was willingly- he smiled and asked to sleep on it. When he laid down on it and I covered him- he was calm and smiling. In the pic I provided he is calm and holding his door (his obsession is doors and windows). He even set his door down to hold the fur. For other mommies and papas with spd/autistic kids you know that willingly touching a new fabric and setting down an obsessive item is huge and super encouraging!
I am so grateful to have such a quality item that is affordable for my special needs son. His older sister received one as well as is now pretending to be a sheep. Fun for everyone!
The ONLY negative is that the brand/info sticker on the pelt was a pain to get off and pulled some of the felt - not damaging it but blemishing the unity -but if the skin is down it will not be noticeable.
A super fun detail is that all of the fur is combed out but there were a few strands that were wavy and had a slight curl- I LOVED that.
There was no odor at all which is great! I expected an animal smell which is better than chlorine or dioxin which is what competitors use in their process.
There is no noticeable seam in the middle on the top where the two pelts are gathered.
I am soooo satisfied!

Exactly as described and what I needed.
Size: 2' x 6' (Natural), Color: Wolf Tipped
I have a bad back along with other medical problems. I bought this for padding in my wheelchair. Very thick, soft, flexible, everything I needed. No smell and very little shedding even initially. Arrived quickly and well packaged.

Feels soft and looks great, just make sure to measure
Color: White+Black(Grey)
We ended up returning it because it was too tight to fit our console. Just make sure to measure yours. Still, 5 stars on quality.

Love it
Color: White+Black(Grey)
This is amazing. Thick and fluffy, but not so much that it would be in the way. Easy to install and now that surface is protected and comfy.
