I have old carrier 50zp060511s Air Conditioners that having voltage details like 3ph 220V 60hz UL Standard But now i have voltage of 400V 3ph & 230V 1ph.. is there any solution for this issue..

If you are reading 400 volts coming into the unit, call electric company. You should only have 220-240 from your power lines. Anything over that will burn out unit. P.S. In my opinion Carrier Units are the best and longest lasting when properly maintained.

Fix problem on carrier furnace heating blower relay click sparks click again got used mother board does same. Did I just get another bad relay or something else doing it?

It is more likely the motor or the fan causing the problem at this point [or you got a bad used board].
First with the power off try rotating the fan by hand to make sure it turns freely. If it turns hard or is stuck you know the cause. If it has places to oil the bearings, add a couple drops to both ends of the blower shaft and the motor shaft and try spinning again by hand. It could be the blower relay contacts are burned and making bad contact or possibly the motor capacitor or start windings are bad. Without a model number, I can't tell what controls your unit uses. At least Carrier is one of the better companies in providing manuals and wiring diagrams.

If you are electrically handy, you might try energizing the motor relay without the control board connected, there should be a wiring diagram on the inside of one of the panels.

Display F3 on carrier Ac what problem

Well without a model number, I can tell you this. On some models, F3 indicates fan speed 3, which is high speed.If you push the mode button, these units will switch between f1, f2, f3 and smart fan. No problem.
On others, F3 indicates a fan speed error, either something is keeping the fan from turning, or there is a bad or loose connection somewhere.
On still other models, F3 indicates a freon leak or problem in the refrigerant circuit.
If carrier made their own units, they would probably act the same, but they don't. Model number is important, since the unit could be a daikin, LG or Samsung under the skin...

The reset button that came on the cord of my Fedders model AED24E7F-C keeps tripping after a short while. Otherwise the unit blows cold and works fine. I can hit the off button when it is working fine...

Do you have anything else on the same circuit? I have heard about many of these units, not just Fedders, that will not run on a circuit that has another appliance or something that is pulling a lot of amperage. Also, check and make sure the receptacle is not worn and the plug is loose fitting. Other wise, you definitely could have a weak internal connection in the cord. Hope this helps.

I replaced the power cord on a carrier ac window unit 24000 btu model yc-d , now the compressor will not shut off regardless the thermostat setting

You have probably one wire in the wrong place on the back of the switch. There should be a wiring diagram near the electrical compartment on the window unit. It will show you where the wire needs to be. You are probably just a terminal off.

AC window unit pops circuit breaker

Tripping breakers and your cord getting 'noticeably' warm to the touch are both 'bad' signs - and the most likely problem is either your compressor or fan motor is getting ready to 'quit' on you - which constitutes (in most cases with window units) making the smart move toward a 'new' or 'newer used' air conditioner.

There are however a few things you might try:

First - up-plug the AC and take it out of the window

Second - take the outer cover off - so you can see inside real good. Look for 'loose' electrical connections (loose connections generate excess electrical heat) - "tighten" any connections that are loose. Note: be sure and check the plug - see if the prongs are loose/wobbley, (if so you might need a new cord) check where the cord ties into the window unit - check the electrical components to make sure their connections are good and tight - any wires you find 'wire-nutted' together (with those colored plastic wire nuts) - take them apart and 're-do' them - making sure they are tight.

Check the connectors on the"capacitors" (grey/silver/black items from the size of a pack of cigerettes to 2 or maybe 3 times that big) - make sure they are tight on the connectors.

You may have to take the (spades) off the connector and using pliers - crimp them down so they will fit the connectors good and tight.

On the compressor itself - follow the wires (usually 3) to the little removable cap (usually a metal clip holds it in) - take the clip off and pull the plastic cap out and you can see the compressor terminals. Be sure the wires that are attached (usually with wire spades) are good and tight. If they aren't - carefully remove them - re-crimp and re-install - making sure they are tight. Note: in some cases you might need to put a new spade on the wire.

After doing all that - take a water hose and make sure both coils (evaporator where cold air comes out and condenser where hot air comes out) are good and clean. Note: you don't have to be 'real' careful with the water - but try to not get water in the electrical components/wires.

You have to make sure they are both 'real clean,' and of course the filter that goes in front of the evaporator coil must be clean - but you indicated you've already changed that.

Hopefully - you will find some seriously loose connections and once you get them tight and the unit washed real good - you'll be ok, but if it keeps tripping breakers - and the AC cord continues to feel excessively warm to the touch I would think you will need to start thinking about either a Service Tech to repair the AC or buying a new/different one.

As I noted above - if it's a fan motor or a compressor that is bad - you are better off (since your unit is already 7 years old) in my opinion to try and secure a new AC or a fairly new used one - 'especially if it's the compressor.

If it's the fan motor - and your Service Tech gives you a 'fair' price for a changeout, i.e. 'half' what a brand new unit of the same size would cost - then I'd probably let him do that - but try and get a warranty from him of at least 90 days (parts and labor).

Good Luck!

What type of freeon gas does it take

There should be a nomenclature tag on the exterior of the unit by where the electrical enters the unit. It states the refrigerant type .
