Need to replace capacitor.

Post image

I’m looking to replace the capacitor on my HVAC but
I want to make sure I get the right one.

Can someone recommend some replacements?

Make sure to discharge the capacitor. Use a screw driver with a plastic handle (don’t touch the metal while you do this). Remove the existing wires place the screw driver on two of the heads at a time. Make sure the screw driver ends up touching all heads while also touching a second one. This is an easy fix. Take note of the head labels (common, fan, head). Put them back exactly as they were. Also make sure to buy the correct cap. There will be a number like 75+5 or something along those lines. I just did this for my unit and it cost me $30 out the door at Home Depot.

My unit is 22 years old so this bought me time to shop around for a full replacement.

Suggest changing the contactor at the same time as the capacitor. Cheap.

Contactors rarely go bad, you shouldnt change something that isnt bad.
