Lol. Good answer Tom. When looking at the contactor does only one side pull in and the other is bridge together (single) OR do both sides pull in when energized (2 pole)

Is this considered a single throw switch or a tripple throw switch and what's the difference


We cannot see the product you are asking about
Example single throw switch is household light switch ..., flip the switch either direction and load turns on-off.
Example double pole switch is 240 volt double breaker... flip the breaker and two wires turn on-off.
Example triple pole switch is any 3 phase contactor or 3 phase timer ... flip the switch and three wires turn on-off

Contactor diagram ruud ac


The 030 model is a 2.5 ton system, so it is not going to utilize a very big contactor. If you're not that familiar with wiring, take a picture of the contactor, turn the power off to the outdoor AC, make notes on where all the wires are attatched & remove all the wires. (Note, you also need to turn off the indoor unit which supplies 24 volt control voltage to the outdoor unit...in other words, turn off you furnace power). Remove the contactor, take it to a local electrical supply house & they will match it. Replace it by reversing the above steps. If you are deadest on ordering online, look @ the white sticker on the side of the contactor in your AC for the ratings. Really the only thing you need to find is the VA rating. On a 2.5 ton system, it is probably only about a 20VA. Get a double pole contactor (brand doesn't matter), 24 volt coil, with the rating on the existing contactor (if you are not sure, a 30VA contactor will do) When it comes in, plug & play.

Replacing double pole 220 v with honewell ct410a two wire120/140v wiring diagram not clear


1 power wire (120v) will go to the thermostat and 1 power wire (120v) will go directly to the unit. The other wire on the unit will go to the other side of the thermostat. The safety precaution behind using a single pole to replace a double pole contactor is that you will always have 1 leg of power going to the unit. Many systems are designed like this from the factory, but it is always better to have a 2 pole to cut all power off to the unit unless it's in operation. The unit will still not work as long as it does not have both legs of power.
L1 to Thermostat T1 to Unit
L2 and T2 wired together.

This is only for 240v systems. 120v Will have 1 common and 1 power, therefore you will need to know which wire is which. Power to thermostat, common wired direct.

Where can I get a double pole contactor for my goodman ckl60-1


Hi,
I buy all of my contactors at www.grainger.com

Match up the coil voltage 24v
The number of poles 2
The contactor rating...in this case it should beat least 40 amp.

You can find them buy searching the site for "definite purpose contactor"

They are very efficient and will ship quickly from the closest warehouse...I usually have my stuff UPS the next day.

My Contactor went out on my UPKA-031JAZ I went and was told a Honeywell DP1030A5013 contactor would replace the one that went bad. So how do I wire the Honeywell to the old one since they don't look like...


this is a single pole contactor, Look at them both closely, Notice that there is a bar which goes directly from one side to the other, note all the leads that are connected
mechanically from one end of this bar to the other including the spade connections.

On the other "Leg" there is a similar setup. In this case the contactor breaks the
connection (It may have a bug cover). All the leads on this leg make connection when
the contactor is closed including the spade connections at each end. It is a big switch.

The 4 spade terminals on either side are the ones which control the coil.
Make a drawing and take a picture with your cellphone to remember where each
wire goes.
I remove the wires one at a time and switch them out. Make sure power is off to both
the inside unit and pull the disconnect for the outside unit and check before servicing.

They may look different but if you pay attention to the orientation of the solid bar
it should become apparent. Hope this helps.

Capacitors and contactors for Goodman air conditioner


I havent had luck in finding a part list for you but have you tried to look at the label on the motor(s) to find the capacitance? Or try on the existing capacitor? Dual caps are usually listed as 35/5uf or 35/5MFD on the actual part. There are only a few variances of contactors for residential systems normally 30-40va single pole single throw (spst) or 30-40va single pole double throw (spdt) singe throw contactors have four contacts for 220v and double throw contactors have two contacts for 220v and a constantly hot leg.

I need assistance with swapping out a contactor.


I don’t believe changing the contactor to a double pole contactor will solve this problem. It appears by your description that bugs are being attracted to the contact points on the contactor. Changing to a double pole contactor will not eliminate that problem but only provide another contact point for the bugs to be attracted to. The most effective solution would be to replace the current contactor with a sealed design where the contact points are totally enclosed. Enclosed contactors are completely enclosed protecting it from bugs and dirt. These type of contactors are available in the single pole design so no further wiring modifications are needed. You can consult a professional A/C service company like mine for more information and assistance.

Hope this helps. Let me know if there's anything I can do for you!

Buzzing on unit


It sounds like the buzzing is a bad coil. the part is not carried at Home Depot you will have to fine it at an A/C supply house.
there are different types. there are single pole and double pole.
single pole have one set of contacts. doulbe pole have 2 make sure to get the right one. also make sure you get a 24 volt coil.
you could maybe order the part on line.
When changing the contactor. SECURE POWER to the condenser and the air handler remove the existing contactor from the cabinet leaving all the wires connected to it if possible. you may have to disconnect the power leads comming in. Swing it out of the way. Install the new contactor in place then move the wires one at a time matching location from old to new. Do NOT
get them mixed up. Or you could make a drawing of the part on paper locating the wires so you then may return them to the proper location. If you feel this may be to difficult for you call a service company and ask there charge to replace a contactor.
The part is usually @ 12.00 to 15.00 our cost so the part should be @ 30.00 0r 40.00 retail. then a service call charge.
good luck if you need more help let me know
