CARRIER HN51KC024 (Alternate for 3100-15Q228), 1 Pole, 24 VAC Coil, 30 AMPS, 50/60 HZ, CONTACTOR

First time installing one of these. The process was straightforward as long as you take pictures. I now have cold AC. It seems to be of good quality.

In less than 2 minutes I had this installed and our central air back up and running. No complaints at all, great price and a quality product.

Look different than the picture but still works perfectly. Good product.

I have a 20 year old Carrier split HVAC system, so I am just trying to get another couple of years out of it before it has to be replaced. This is part of that maintenance. If you are mechanically inclined, it is super easy, just one for one replacement. Just take lots of pictures, that is what I did. So far, I do recommend it!

Right part, quick shipping, just what I needed

Same part number as my old contact but did not have the numbers imprinted on top. Turned off power at the breaker before starting. Took lots of pictures of the old one before removing (16 year old unit). Also verified all wiring per the wiring diagram before turning the power back on.

our A/C wouldn't turn on and the nest thermostat said there was a problem with the wiring, which was vague. I replaced it with a different thermostat and the 3a fuse on the furnace board kept tripping whenever I tried to turn on the A/C. I replaced the capacitor and the contactor, and now my a/c works again. the old contactor had a resistance of 2 ohms and visually, you could barely tell the windings suffered heat damage.

Good product and almost exact replacement for carrier part. Just be aware that this is not original carrier product or an OEM version, this is a similar item.
