Compatibility & Fitment
- For use in HVAC systems, central air conditioners, heat pumps, and condensing units.
- Powers both a compressor motor and a fan motor from a single component.
- To ensure fitment, verify that your system's required specifications match this capacitor's MFD rating (30/5), voltage (370V or 440V), and physical shape (round).
When to Replace
- Compressor or fan motor fails to start or experiences a hard start.
- A humming noise is heard from the unit, but the motor does not engage.
- The air conditioner unit is running but blows warm air.
- The capacitor case is physically swollen, bulging at the top, or leaking fluid.
Installation Tips
- Disconnect all electrical power to the HVAC unit before servicing.
- Safely discharge the existing capacitor to avoid risk of electric shock.
- Note the wire placement on the old capacitor's terminals (C, FAN, HERM) before disconnecting.
- Connect wires to the corresponding terminals on the new capacitor.
- Ensure the capacitor is securely mounted within the unit's housing.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
