Ultra Durable 15 MFD uf ± 5% MFD 370 V VAC or 440 Volt Oval Run Start Capacitor by BlueStars - Replacement for AC Motor Run or Fan Start and Cool or Heat Pump Air Conditioner

Worked well that replaced my 25L756 hvac system capacitor.

Plugged it in and my 5 ton a/c unit is up and running. The real test will be how long it will last in the summer heat!

Ingersoll Rand 60 gal. S3 Air Compressor back up and running. I'm happy.

My adventure began with the installation of an Ecobee thermostat. While the heater functioned perfectly right away, the air conditioning did not fare as well. The compressor would start, but the fan refused to spin. Stepping outside to investigate the issue, I quickly realized I was out of my depth. Nevertheless, I decided to give it a shot. I noticed a dual capacitor in the unit and ordered a replacement. After installing the new dual capacitor, the fan still didn't budge. Next, I thought the fan motor might be the culprit. I ordered and installed a new motor, but to no avail. Upon closer inspection, I found there was a second capacitor. I ordered this second capacitor and decided to replace the contactor as well. Finally, after wiring the new fan motor and using the two new single-run capacitors, everything sprang to life! My 1983 Rheem 2.5t A/C condenser unit was up and running again. (FYI the house came with it, will replace one day but works just fine!) Here are some key takeaways for fellow DIY enthusiasts: Diagnosing the Issue: If your fan isn't spinning, check both capacitors (if present) and the fan motor. Capacitor Replacement: If you have a dual-run capacitor, consider using two single-run capacitors instead. Ensure the microfarad (uF) ratings match your compressor and fan motor specifications exactly. Wiring: Follow the wiring diagram for your specific unit. If the original diagram doesn't work, consider alternative wiring setups, but ensure all connections are secure and correct. I’m attaching a wiring diagram for anyone with the same unit. Remember, the uF ratings are crucial—make sure they are accurate for your compressor and motor. If you're unsure, a quick Google search with your unit's model information should help. In summary, after several attempts and a lot of trial and error, I’m thrilled to report that my A/C unit is fully operational again. The single-run capacitors made all the difference. I practically rebuilt my A/C, and would have possibly not ordered the fan motor if I would noticed the second capacitor. Happy DIY-ing!

bought for backup for when we lose power sometimes when it comes back it will blow the capacitor. it is easy to replace and saves the service call charge.
