### ⭐⭐⭐⭐⭐ Problem solved
*by T***N on May 27, 2025*

Fixed the problem I had

### ⭐⭐⭐⭐⭐ Fixed my AC
*by S***A on April 25, 2025*

A little bigger diameter than the original one from my RV A/C unit but it fit by adjusting the bracket and works great at 1/3rd the cost.

### ⭐⭐⭐⭐⭐ 40/5 mfd capacitor
*by H***Y on March 23, 2025*

It took 2 shipments, because the first capacitor was bad. But capacitors are finicky so I tried to exert some grace and reordered again from the same supplier… Bingo 2nd order was perfect. I got no grief from requesting a 2nd order so here you go 5 stars. Thanks !! It’s good to have a capacitor tester…
