    Worked on a Lennox XC14 5 Ton Condenser
    This contactor worked perfectly on my Lennox XC14 series 5 ton condenser. The only difference was that my original contactor had screw terminals on the top/output side and this one has screw down lugs. It was easy enough to clip off the ring connectors and insert the bare wire into the provided lug screw terminals.Replacing this was great preventative maintenance as my 7-8 year old contactor was badly pitted and a likely candidate for failure in the near future. It’s so much better to spend about 11 bucks here and do it yourself than to spend 200-300 dollars to make an urgent call to your local AC guy. Bottom line, if yours is more than 5 years old, it’s cheap preventative maintenance to replace it yourself now while it’s still working!I bought two so I’ll always have a backup on hand.Another side benefit is that the condenser runs quieter now. I didn’t realize how much noise the old contactor was making. I seriously thought that maybe the compressor was not running after I finished. Nope, it’s just quieter now!

    Great value, two of these saved me over $500 quoted to replace old, pitted contractors for home HVAC systems (2) already covered with period inspection maintenance agreement. Btw- the service quote included maintenance program discount for customers- ha.

    I liked the match replacing my Lenox contactors for simple disconnect and reconnection, even the mounting bracket holes matched. I did have to cut and strip a few of the wires on each.

    Tips:
    - Take before photos of wire connections
    - Ensure a good moel match that meets or exceeds ratings.
    - Ensure both outside HVAC unit and control power is off, for control, I flipped breakers on my internal home fan units.
    - Replace one, then confirm working well before next. I spaced my replacements several days apart.

    The new contractors are still working fine as of 7/28/2019.

    Well made and lasts longer than cheap contactors. Don't skimp out on the contactor. It'll fail on the hottest day right at the end of the day and screw you, guaranteed. Bought this a while back and it's still going strong thru our 110F summer we've had.

    4.0 out of 5 stars This contactor working perfectly after 2 years.
    Reviewed in the United States on February 7, 2015
    Verified Purchase
    Working perfectly after 2 full ac seasons in a mid-Atlantic state. I am not an HVAC technician but an educated homeowner. Just made sure it could handle the 24 volt control circuit and had at least 30 amp at 230 volt capacity. It is 40 amp, all the better. My original contactor on my 20 year old Ruud condenser was looking burned at the edges of the points AND the compressor had chattered once or twice while starting which makes the house lights flicker. When I bought this contactor it was only $6.00 and I could not believe it could be any good. But since the old one still worked for a spare, I bought this one and installed it with some minor wire terminal modifications. The famous Packard name sounded good. Yes, made in China, but just about everything reasonable priced is today. If you buy a contactor made specifically for this Ruud, they are priced at $75+ here on Amazon and some of them are made in China too! With a 100% part markup and a minimum HVAC service call of $120 plus time around here you would be over $300 for this repair when it did fail. Plus you are going to be told you need a new condenser unit at 20 years old.

    5.0 out of 5 stars EXACTLY what our Central Air needed
    Reviewed in the United States on September 13, 2013
    Verified Purchase
    I had had an AC repairman come out once, to fix the Central Air after I noticed the lines had frozen up and the fan was running constantly. He did some poking and prodding, worked some magic, and $150 later I had my AC back and had signed up for a yearly maintenance plan. Fast forward a year, to the end of the last cleaning/check in my new service contract. I needed to cancel, since my fiance and I had both been recently laid off. A week later, I woke up in the morning to frozen pipes and a hot, running fan!

    Since we were working to save money, we decided to just pull the main fuse and leave the unit disabled. It was fall, and while it's warm in MS, it's not THAT warm, and we could do without the AC. Thankfully, we had a mild winter, and didn't need to run the heat at all! This past summer, when we went to start the AC unit up again, we had hoped the problem would resolve itself. Not so much! Within just a few minutes, we once again had frozen pipes. UGH!

    Some research using my Google-Fu led me to understand that this problem was usually caused by a bad contactor. When I read that, the word contactor clicked for me - I remember the repairman talking about it, and saying it would only cost $50 or $75 if I signed up for their annual maintenance plan!!!

    Some more reviews and quick checks outside led me to finding the right one, right here, on Amazon. They were so cheap, I ordered TWO. Replacing it was a breeze - my fiance did all the wire work, but it was really just a matter of keeping everything in place, and tightening connectors. We used my phone to take pictures prior to removing the old contactor, to ensure the new one went back in correctly. Once it was in, and the main fuse was returned to its outlet, the AC unit started chugging along just fine!

    We still have the second contactor, sitting on a shelf, ready to go when the current one decides it just can't take it anymore. And when that one goes into the unit, I'll gladly return here to Amazon to buy two MORE. And if we happen to move before we use them all, I'll gladly leave them with the new homeowner, with instructions on how to save hundreds of dollars by doing research and trusting yourself!

    5.0 out of 5 stars A bargain (so far).
    Reviewed in Canada on June 28, 2019
    Verified Purchase
    So far, so good. I ordered this as a replacement for a Siemens FLA 25 contactor with a failed coil because of its low cost and higher current rating. I had reservations, thinking the existing 120v power feed wires might be too small for the screw terminals on this unit, but there seems to be a good contact area and are mechanically secure. I'll keep an eye on them anyways.
    The bladed terminals for the other wire connections appear to be brass; on the Siemens unit they were silver plated, but the plating was coming off of some of the blades and and rust was starting to develop. The coil/core is enclosed on the new unit but was not on the Siemens; a couple of bugs (literally) were within the travel spaces of the contactor core in the Siemens unit and may have contributed to the coil failure.

    Beware of replacing a shunted contactor with a two pole unit. I have a heat pump. During cold weather the shunt provides continuous power to a defrost control unit when required, to facilitate heat pump operation when heat is called for.

    Otherwise, this unit seems as solid as the old one and is presently operating well. I can't assess the quality of the main contacts - hopefully they are at least as good as the original unit; it lasted 10 years. Hopefully the new one does at least half as well. A bargain if it doesn't fail in short order.

    Used it to replace an old-school (early 90's) single-pole contactor.

    Tips:
    - Take a picture before you start!
    - Contactor inputs (line 1, line 2) and outputs are labelled on the contactor.
    - If you have an old school contactor, you'll notice this one has less output pins. That should be okay. Usually, the extra pins you have on the old-school ones can be moved on the output side of this contactor (e.g., in my case, it was going to the startup capacitor)
    - You can use a two-pole contactor in place of a single-pole one. There are good videos out there explaining why.
