The service guy says the contacts are burned on my relay. He want's $160 to replace it. Do all contactors operate/activate on 24 volts?

Yes, mostly, and I was able to fix my AC with the $6 unit I bought at Amazon.

As far as I know, all HVAC systems in the US are 24VAC / 240VAC split systems. The Thermostat and contractor are 24V, the Compressor is 240V. If you do it yourself, please remember to pull the blade as well as turning off the breakers.

99.99% of the residential type units made since WW2 use a 24 volt coil so you should be okay. Just remember to shut the power off before you change out the contactor

Yes, the A/C thermostat sends a 24volt a/c current to the relay in your air conditioner outside and the circulation fan on the inside. When this current is sent it trips both of these relays and starts up the compressor and circulating fan. I changed it myself.....took a few pictures to be sure o hook up the same way and all worked just fine. $160 sounds like a lot to me! Good luck.

Yes, but make sure you get a schematic of your unit (try Google if you don't have it) to confirm the type of contactor. Some units operate with one pole contactors, some with double pole. It's important to keep the same type, because depending on your unit some things do not need to be non-energized at start-up time. Replace all leads where they go, and first and foremost: throw the breaker off. Good luck!

I'll check with a thermometer later but it should be warm enough to notice. Also, it takes a few minutes to get rolling. I would suggest flipping the heat switch on and off about half a dozen times; the contacts may be oxidized if it was shipped through a moist location. Simply opening and closing the switch may be enough. I had the same trouble recently with some surge suppressors.

I'm not sure about that. Mine clicks on my Volt, so I'm wondering if you shouldn't contact Schneider to ask them directly.

I hooked this unit up and switching between the two contacts, I can see a slight difference in the brightness, Hooking it up to a current meter confirms this, with the draw being ~300mA vs ~400mA. I don't know if the difference is enough to notice, I would suggest testing them rather than just replacing them and assuming that it is fine.

that's the one I used for my unit. The best way is to look at the numbers on your old contactor, and see which contactor replaces it. Comfort Gurus has a page with a list of which new contactors replaces the old ones. If your contactor is old, you won't get the exact contactor as your old one because it's been updated. You may want to look a web site of how to connect the new replacement contactor, for the most part it's the same way.

The contacts can certainly handle that voltage , it's the amperage you need to be careful with . The pick-up coil will turn to smoke in a nano second at that voltage but I bet you have it wired for a 12 volt trigger (switch/relay) to activate it .

No, the coil that activates the relay is 120VAC - use R04-11D30-12 for a 12VDC coil and contacts that can carry 30A at 120VAC

It will not work with 24 volts. I don't recommend this unit to anyone as mine stopped working after 6 months and I had to replace the unit! I am not a happy camper with Amazon!!!

Well, yes, as a matter-of-fact.... 1-800-629-3325 ext208 Andrew Miller, Service Manager.... It took a minute for him to answer but he was helpful and direct. It has "been awhile" and I don't know if he is still there, but he helped in my question about grounding, (that IT SHOULD BE grounded...) I also spoke directly to a sales person when I ordered mine, and he was very helpful. I guess it depends on how "you-approach-them." ... btw, I've had NO service issues with my 4400E (purchased DEC 2010,) and it runs fine... I DO run the tank and carb completely dry after each test run-every 3 months, using PREMIUM gas 90+ octane. I remove and store the battery indoors, and the genny covered in the garage...

This would not work because it is a 110 v and your sensor comes out with 24v. I think that you would be better off with this relay from Grainger http://www.grainger.com/product/OMRON-Enclosed-Power-Relay-2XC19?s_pp=false&picUrl;=//static.grainger.com/rp/s/is/image/Grainger/2XC19_AS01?$smthumb$

I have seen sockets for this relay however this seller doesn't include it. I have seen them around sold together if you don't see it here check on ebay. hope that helps!

I have had to replace one unit due to power surge from lightining. Assuming your 120vac source is good, (test or have tested by competent persons), open the outer and inner doors and inspect the contacts. If the transformer output is 24vdc, check the circuit board on both sides, (a few phillips screws will remove it from the housing), for signs of over heat or shorting out. If no visible signs exist, contact Orbit customer service http://www.orbitonline.com/contact or 8004886156. They are extremely helpful.

This relay is activated by a 110 volt signal on its own cord. I have been using them to relay both 220VAC on a 30amp breaker and 110 on a 20 amp breaker. They work quite well. Any system that will switch the 110VAC on and off can operate this unit. Hope this answers your question. Alan PS if you have a system that only has dry contacts you would need another relay for the 110VAC to make this work and at that point, you would be running a relay with a relay and that doesn't make a lot of sense.

No, you will need the new remote made for this pack. Small price to pay for vastly improved performance of the contactor.

Not 100% sure what your question is, but the manual says "SPST Output Relay Contacts electrical Ratings Full Load Amperes N.O.: 12 A Locked Rotor Amperes N.O.: 72 A Non-inductive Amperes N.O.: 10 A Pilot Duty: 125 VA @ 120 V"

I do not know if you can buy the contacts.. but I would just open it back up, put the wire back in and solder it in using solder and a little plumbers type torch.
