Easy DIY
Perfect replacement for my old and failing furnace fan run capacitor. Took me under 5 minutes to switch it in. Saved about $120 in heating and AC service fees.

Perfect Capacitor
Great price. Fast shipping. Measured up on delivery at 4.20uF so within 6% tolerance for this 4uF capacitor.

Life saver
Thank you so much - old capacitor died right at the start of a heatwave. This got here in two days and was a 3 minute install. Everything’s back up and running now. If installing yourself always make sure to safely discharge the capacitor and kill the electricity. Otherwise all you probably need for the job is a flathead screwdriver.

Run capacitor for AC unit
Installed this in a 33 year old Ruud AC unit. Was unable to read uf on the old one. 1/6 hp motor on fan so I went with a 4uf capacitor. Newer motors this size take a 5 uf but as old as this one was I decided to go with a 4uf. Fan sounds good on start up and run. Hope to get a few more years out of this old AC. All ready got my $ worth over the years.

Resolved all faults.
This item immediately got my aging Trane XR90 back up and running properly. All faults have cleared and the furnace has run accurately since installation. Takes ten minutes to install.

Didn't work for me
It was the exact same capacity and voltage as the one I replaced but it made my motor overheat. Had to put the old one back in.
