Have a Dayton Mod #6K176. Was checking to see way motor just hummed. Found a lead off one of the capacitors. When trying to reconnect several other came off. now I need a wiring diagram to show how capacitors are hooked up. It has 2 rounning Capacitors & 4 Starting Capacitors. Thanks Glen

single phase 240VAC. data late will have info. 3 phase usually has 12 leads.

It appears this is a 7.5 microfarad (mfd) capacitor like the ones installed on fans. If your fan motor has two brown wires, in addition to the black and white power wire, just fasten the two brown wire to the leads on the capacitor and insulate the connection with electrical tape and mount the capacitor in some dry convenient location inside the controls section of your unit. Be carefull to mount the capacitor in a location where it does not short an electrical connection.



If the capacitor is replacing the low side of a dual capacitor, for example a 35/7.5 capacitor, extend another lead from the common side of the dual capacitor to one side of the 7.5 capacitor and place the one brown lead from the fan motor to the other lead on the capacitor. If trying to replace the lower side, it is better to just replace the dual capacitor.

Capacitor Failure Symptoms are sometime harder to identify without the right tools and expertise. Capacitors can be found in several different sizes and shapes. There may be one or multiple capacitors included in your ac with regards to the design. While the most popular capacitors are the types found on circuit boards, the ones most associated with air conditioning will be the bigger capacitors that assist start and run your motors. There are several motors present in an conditioner and heater systems:

1. Compressor Motor Run Capacitor: Here is the most popular capacitor that fails. Most of the time these are duel capacitors, which means that there are 2 capacitors built into one. A duel capacitor will have three terminals on the top where a single capacitor will simply have two terminals on top.
2. Outside Fan Motor Run Capacitor: That is the smaller capacitor found with or part of the Compressor Motor Capacitor. It helps start and run the outside fan that blows air through the outside coils.
3. Indoor Blower Motor Run Capacitor: Similar to the outdoor fan motor capacitor, it is a small, single (two terminals) capacitor that will help start and run the indoor blower motor.
4. Start Capacitor: Some models include an auxiliary start capacitor that helps jump start the motors. Most are found on the compressor. These are less common.

You may need to get that checked out.
Air Conditioning

From what I can find on the internet, there should be a plug very close to the motor body that can be reversed to reverse the rotation of the motor. It should be a small rubber plug on the wires leading into the motor.
Also, check inside the wiring compartment for a sketch or notes.

Most of the time if there is power to the motor and all it does is 'hum' then you have a bad motor.
Before replacing it however - I would look at it's capacitor (a small device, usually silver in color, about he size of a pack of cigerettes) and see if it's visibly 'bulged' which is most always an indication that it's bad. If it is - you could solve your problem by changing the capacitor. Also, you could check for electrical connections that have burnt off or have come loose. There is just a slight chance that the capacitor/wiring is your problem - but it's worth checking out. If not, then you will need to get an AC tech to troubleshoot the system, unless you decide to just replace the motor yourself.
Note: If this is a 'central unit' with an 'outside unit' and all it does is 'hum' there is slight chance that what you are hearing is the 24V causing the contactor (in the unit) to hum which is pretty much normal - however - if this the problem and the outside unit is not running (only humming) I would check my fuses and breaker. You could just have a blown fuse or a breaker that needs resetting.
ALWAYS make sure the electrical power is completely OFF before trying to make any checks/repairs.
Hope this helps.

Hi,
The brown wires go tto the capacitor...

Here is the page

http://www.grainger.com/Grainger/wwg/search.shtml?searchQuery=4m098&op=search&Ntt=4m098&N=0&sst=subset

On the top right of the page you will se that the cap. is a REQUIRED accessory....buy it and hook it to the brown wires and the motor will run...

Should only be 2 except maybe a case ground.

In the **********, the screws will be market L1 & L2. There will also be a jumper that needs to be connected between the 2 terminals for 230V.

the hum is probably the main pump powered up but not turning. the pump is an induction motor and a usual fault is the motor capacitor. try to access it, find the value of the capacitor and replace. it is a cheap part
