Replaces / Cross-Reference Part Numbers
- Replaces any round dual run capacitor with matching 70/10 MFD and 370V or 440V specifications.
- Commonly replaces capacitors in CBB65 and similar series.
Compatibility & Fitment
- Designed for HVAC applications including air conditioners, heat pumps, and condenser units.
- Powers a compressor motor (HERM terminal) and a fan motor (FAN terminal).
- Verify specifications (uF, VAC, and physical dimensions) of the original capacitor before ordering.
When to Replace
- The fan motor runs but the compressor does not start.
- The compressor or fan hums but does not start.
- The unit starts but then shuts off intermittently.
- Visible signs of damage, such as a bulging or leaking capacitor case.
- Capacitance measures outside of the ±5% tolerance range when tested.
Installation Tips
- Disconnect all electrical power to the HVAC unit before servicing.
- Safely discharge the existing capacitor by shorting the terminals with an insulated screwdriver.
- Photograph or note the wire placement on the C, HERM, and FAN terminals before removal.
- Ensure the new capacitor is physically secured with the original mounting strap or bracket.
- Professional installation is recommended for those unfamiliar with HVAC electrical systems.

Worth Every Penny!
Size: 9, Color: Coyote
I absolutely love these boots! They are super light, comfortable and definitely waterproof. I took them on a camping trip for the weekend and I walked through creeks and puddles with no issues at all. No water got inside and they were comfortable all weekend. The only thing was the tongue did start to bother me a bit after the 3rd day. I have some pretty boney shins but a small cloth between my shins and the tongue helped a lot.

Excellent boot for the price! Very solid. Cushy insoles very comfortable. Wide width plenty wide.
Recommend getting half to full size smaller than your usual.

Don’t hold up/good Customer Service.
Size: 10.5, Color: Army Green
Please read full review. Where to begin. The boots are comfortable, decent waterproofing, they feel/look well constructed. Unfortunately they did not hold up well, I hikes less than 10 times. My left foot began to hurt on top near bottom of the lace, I tried every lacing method and it still hurt, leading to potential blisters. It was not a break in issue the boots were initially comfortable to wear then around hike 6 they hurt.
Reached out to the company they were partially helpful offering a coupon on their website. Their shoes are significantly higher in price on their website. It could have been a lemon pair of boots. Buy with caution.
Updated: 4/9/26-CS reached out to me and offered full refund or new pair of boots. I do hike often so I went with the new pair of boots. I will create a new review in the future /update this review. A+ for their CS. Initial review was 2 stars I increased to 3 stars if these boots hold up the score will go higher.

Nice Grill Cover
Size: 55 Inch, Color: black
I bought this as a replacement cover. It's durably made. It's not too thick or heavy. It fits nicely over my grill. The handles make it easy to put on and take off.
