  • 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.

Comfortable, relaxed fit semi-dress suit that fits true to size. Don't round up or down in size.
This suit fits true to size. We got the 9-10 size in white/tan for our above average height 7 year old, and the suit was just a little big (te Amazon algorithm recommended 9-10 based on past purchases and timing. He is the large side of his 2nd grade class, despite being one of the youngest, so I would say this suit would start fitting an average 8.5-9 year old boy. The fabric is a relaxed summer fabric, so good for semi-dress relaxed events. Our tan suit (and from the weathered gray/blue/green images, I assume all of the suits) seems like a casual menswear commercial shoot. The fabric isn't scratchy and our son said it is comfortable. It includes the picket flower, but I didn't think much of that plastic bloom.

Really cute suit for my son. Worth the price.
Color: Grey, Size: 10-11 Years, Color: Grey, Size: 10-11 Years
My son says he likes the color. He is 10 and we ordered the size 10 to 11 however he’s on the smaller side for 10 and he definitely has some room to grow so it will last us a while and it looks a little baggy on them for right now. However, the fabric is good quality. We like that it comes with a pocket square built-in and also the boutonniere for fancy occasions. I think this would be great for a wedding party or other occasions where you’d need more inexpensive but matching suits. Fabric quality reflects the price. The material is ok, but not gonna be an heirloom that’s passed down or anything. In the picture, he had shoved it into his clothes drawers and so it’s all wrinkled, but it actually does look great when it isn’t wrinkly. He’s been wearing this every week to Church on Sunday.

Good quality suit for kids
Color: Grey, Size: 10-11 Years, Color: Grey, Size: 10-11 Years
Comfortable, good-quality cotton/linen blend suit for kids. The suit is lined and he was excited that it has an inner pocket for a pen. I believe the suit fits true to size. In the photo I'm attaching, the suit is too large. I'll explain. We ordered a size 10-11 years, but my son is 9 years old. The suit size is actually a 150 (cm). My 9 year old son is currently 55 inches tall and weighs #61. His height of 55 inches translates to 140 cm - which explains why this is a little big/roomy on him. The product page has a size chart which translates the sizing in years (e.g. 9-10 years) into centimeters. If you measure your child before your order it will help you know what size to order. We haven’t ironed ours yet but plan to iron it when he's ready to wear it. We thought about exchanging it for the next size smaller but it's fall right now and this suit will be better for him in the spring/summer. We were pleased to see that this is a “normal” looking suit. Some of the dressy or fashionable clothes have some quirky or unusual elements to them. All in all, we’re pleased with this suit.

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.
