Replaces / Cross-Reference Part Numbers
- Replaces any single-value round capacitor with matching 45 uF capacitance and either a 370V or 440V rating.
- Universal replacement for capacitors used by brands such as Carrier, Goodman, Lennox, Rheem, Trane, York, and others.
Compatibility & Fitment
- For continuous duty in single-phase motor applications.
- Commonly used in air conditioner condenser units, heat pumps, and furnace blower motors.
- Also used for compressor motors, fan motors, and refrigeration systems.
When to Replace
- Motor hums but fails to start.
- Fan requires a manual push to begin rotating.
- AC compressor does not engage.
- Visible damage to the existing capacitor, such as a bulging or swollen case, or leaking fluid.
- Capacitance measures outside the specified tolerance when tested with a multimeter.
Installation Tips
- Disconnect all electrical power to the unit before servicing.
- Discharge the old capacitor by carefully shorting the terminals with an insulated-handle screwdriver or a discharge tool.
- Confirm the new capacitor's uF rating matches the original part.
- The voltage rating of the new capacitor must be equal to or higher than the original. A 440V capacitor can safely replace a 370V capacitor.
- Note the wire positions on the original terminals before disconnecting.
- Secure the new capacitor using the existing mounting bracket.

Amazing and luxurious
Color: Cream (Double-sided Faux Fur Bubble), Size: Twin (60" x 80")
My daughter said this blanket can be described as luxury. It is soft, plush, and warm. It does slip and slide some, so just be aware that it can do that

Super soft, looks and feels lovely
Color: Cream (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
LThis is a double sided faux fur blanket (with sides have the same slightly bubbled fur. It iz slightly bubbled looking, not as bubbly as the picture makes it seem. The two sides are sealed around the edge, but not sewn or tied in anyway throughout the blanket, so the two sides are free to move on theinside of the. Blanket. It is extremely soft, and my dog, who is old and going blind actively seeks out this particular blanket to make his nest in. He loves it, and so do I. I got it discounted in white, a d know at some point it won't look white any.ore. I'll try to die it after it gets a little grungy looking. Till then, it looks and feels luxurious. I only wish it were joined together in the middle, and more "bubbly" looking. It's a bit heavy by itself for summer nights, but feels warm down cozy in colder times. I got the throw size, it seems a bit smaller than I expected it to be.

Warm and cuddly!
Color: Cream (Double-sided Faux Fur Bubble), Size: Throw (50" x 60")
I love this double sided blanket!! It is sooo soft and warm. I got the creme color. I don’t understand the reviewers that say that it is hard to fold or that it slips against itself. Mine has two edges/seams that are sewn well and it’s simple to fold after use. I just look for the tag which is on one seam and fold from there. Great buy too!!

Great blanket
Color: Grey, Size: King
Liteweight, cooling, and no stray strands. We've had it for over a month and no issues. Also very soft. Perfect summer blanket.
Update: Still no picking issues. I appreciate that the fabric is light and does does not cause our washing machine to become unbalanced. So it still looks good and is great for hot sleepers.
