Packard C240A Packard Contactor 2 Pole 40 Amps 24 Coil Voltage

This replaced an OEM Payne 40Amp contactor. I've never fixed an air conditioner before, but when I took a look at the insides, it didn't look like it would take a rocket-scientist to figure out the problem and remedy it. I was right. A contactor is known as a "relay" in the rest of the non-HVAC world. That's what it looked like to me: a classic low-voltage circuit pressing together contacts for a high-voltage circuit. It was exactly that, and this unit did exactly that, replacing the OEM relay easily. It isn't completely like the OEM contactor. The mounting holes are in a different place, necessitating drilling a couple of holes to mount using the screws from the original contactor. Also, the high-voltage connector lugs aren't exactly like the OEM: the original one had two screw-in contacts for the supply-side wires, and then two screws supporting a wire with a lug on it for the supplied-side. This unit is screw-ins on all four corners. I simply clipped off the lugs on the supplied-side, stripped the wires, and screwed them down. The other wires used crimped-on connectors, and these simply clipped right onto the the lugs of this unit. The last difference is that the relay connectors for the 24VAC control on this unit are north & south on this relay, rather than both on the "west" side like the OEM. So this unit isn't exactly like the OEM, but the difference is insignificant and doesn't affect operation at all. Time will tell how well this unit holds up. If I get 25% of the life the OEM had, I'll be more than happy.

Amazon is amazing! I placed my order this morning with same day delivery. At 4:30 I checked my "order status" and could see an interactive map with the delivery truck moving through my neighborhood and then a few minutes later, an image of the package appeared with the package at my door. The AC contactor was an easy installation (took less than one hour). Although the new part looks slightly different from the OEM part, the mounting base fit fine. Wiring of the new contactor looked slightly different (contacts arranged vertical instead of horizontal), it connected without any issues. Energized the system and my AC works fine. Can't beat the price and service. Part appears to be well made. Very happy with the hardware as well as the same day delivery.

I replaced the fan motor on my AC unit, and it was recommended all over to replace the contactor at the same time. I had a single contractor (where only one leg of the 240v is switched) but I did some research and found out that most AC contractors that run their own business only stock dual leg contactors to save room on their truck. Some manufacturers state that there is some bleed current that goes though the single leg to keep the motor slightly warm. At least on my model, that is impossible because there isn't a neutral to return that bleed current. Switching a single leg is electrically the same as switching both, unless current is being returned via ground (which in almost all cases is not allowed via code). My AC unit doesn't even have a ground electrical connection. If there is a ground connection, it is to 'earth' via the metal supports that hold up the AC unit in the concrete wall. My unit has been running a few days on this, and had no issues with the contactor. The holes lined up with the old one, just had to unscrew the old one and hook up the new one after pulling the main disconnect.

Seems cheap enough for the price, so I bought 2. My Goodman heat pump/ Ac unit is 3 years old and the contacter shorted out and it took out my control transformer with it. it was not fused on secondary side. I upgraded my transformer to industrial control type with a 1 amp fuse so it will blow the fuse and not take out the transformer should it fail again! Fortunately it didn’t burn up my programmable thermostat or nothing else . Out $30 and about 2 hours of my time Much cheaper than $125 an hour HVAC tech on Mother’s Day Simple controls circuit easy to troubleshoot , let’s just hope it lasts for a few years at least 🤔

Outstanding product would recommend this product to others great price

High marks principally for the very prompt delivery. This is a commodity part - a 24V ac 2-pole contactor - which I needed for an Air Conditioning repair in the heat of an AZ summer. My original contactor had failed with a shorted or low-resistance contactor coil which also overloaded my Ecobee thermostat. Once I had diagnosed the original and subsequent problems this contactor rapidly solved my immediate AC problem so that I could run my AC. The coil has sufficient 'oomph' to very confidently slam closed the contacts. What more can you ask? So useful I have now bought a spare to keep on hand for when my other unit fails.

Perfect fit, replaced the original one which was pitted and not making contact. Glad I compared multiple other models to end up with this one.

Due to ants getting into my hvac’s contractor I have to replace it every year or so. I started buying this contractor for the price and it works just as good as the OEM contractor. I’ll be buying 2 at a time for now on, just so I can get my ac back up and running the same day and not have to wait for shipping.
