Replacement contactor for AC unit
Recently blew my contactor on my AC unit which, according to the internet, is a very simple fix. I'm just wondering if this ( Robot Check ) is a viable replacement for this:
mostly because the connections don't appear to be 100% the same. Just want to make sure it will be as easy as the how-to videos make it seem.
Thanks

Welcome to the forums.
That contactor in the link will work fine. As long as you have several close, good pictures of your contactor wiring.... you should have no problem and it's easy for us to see and help you.

Your low voltage terminals are on one side of the existing contactor and you have one on each side of the new contactor. This will work fine as long as you connect the low voltage wires to the low voltage terminals.

Is your existing contactor 30 amp ? The one in the link is .
I personally upgrade to this 2 pole 40 amp contactor .

Very little cost difference . Should last somewhat longer . Wiring might be slightly different .
God bless

Some condensers wire the crank case heater across a single pole contactor to prevent the crank case heater from getting energized when the compressor runs.
I see a spade connector on the hot side but cannot see where it goes.
