Review: Worked for my Portable A\C unit - Worked great on my portable a/c unit that was no longer blowing cold air. Once I replaced the part it works without issues. Before, the a/c unit would trip the circut breaker or turn off constantly from day one. Its been a week later since I replaced this part and it works great! I went with this slightly bigger size compared to what the a/c originally had, but after another review mentioned this would be helpful, I decided to try it and it works fine. Of course, at my own risk I tried it but I needed my portable a/c unit to work instead of spending another $500 to buy a new one.
Review: It works! - My 10 year old Hayward pool pump would only run on low speed. If I quickly switched it from Low to high while it was running, it would stay running on high. Capacitor went bad, It wouldn't give it enough juice to start spinning the motor on high. This capacitor is a direct replacement, even though the model numbers are a little different. The important numbers are all the same, voltage, uF, etc... My old pump capacitor was actually leaking a very sticky substance. Changing it out was very easy, but be very careful that you do not short out. The capacitor by touching both ends with a metal Conductor. Pool filter is now running on high speed!
