Inc. XMCO-321EBBC , Definite Purpose Contactor 32A 1-Pull 24V Coil

Good price and works great.

The American Zettler XMCO-321EBBC Definite Purpose Contactor 32A 1-Pole 24V Coil is a solid, reliable piece of equipment. I keep it as a backup in case our HVAC fails, which is a common failure point. It’s well-made, fits perfectly, and gives peace of mind knowing I have a replacement ready if needed. A must-have for anyone who wants to be prepared for HVAC issues.

So far, so good. Time will tell about reliability. But this is replacing a D15767P02 that was in a 5-year old Trane that shouldn’t have died yet IMO. Another review had mentioned how you have to “flip sides” with the wiring when replacing a Homer. I started to do that, but I think an easier way is to just install this one upside-down to the Homer. For example, if your Homer was mounted with the writing oriented normally, install this one so the writing is upside down. This accomplishes 2 things: 1) the wiring is now 1:1 with the Homer; take a picture of the Homer wiring and match it on this unit upside-down, and 2) your wiring will correctly match the labels on this unit. What I mean is that this unit has terminals marked L1, L2 and T1, T2. The L1/L2 are the incoming line voltage wires. If you install this unit in the same orientation as the Homer but flip the wires side-to-side, your line wires will be tied to the T1/T2 output terminals instead of the input line terminals. Does it matter electrically? Probably not. I couldn’t find anything online about whether it matters or not. And I disassembled the old Homer and I don’t see any physical differences between the L and T terminals.

Works as described. Good product for cheap price

Giving this 4 stars because I haven't used it. I was trouble shooting my AC and this is one of the common problems it turns out I had a bad mother board. I'm keeping this as a spare in case the factory one goes out as well as a spare capacitor, 3 amp fuse and 110v to 24v power convertor. This will work on my Carrier condenser hope I don't need it but if I do I have the part on hand.

Contactor worked perfect. Easy removal, easily replaced. Just be sure power is off to be safe. I replace this part, the condenser, and the AC disconnect all the same day. I did this to know when each part was R/R. I even put dates where convenient. I also changed the transformer in the unit in the attic later the same week.

Direct Replacement for my system.

This is a good replacement. People need to be careful on how to install it such that the shunt line connects the cold/black wire not the hot/red line. As others noted, to match existing wiring, you may need to install it flipped up side down.
