SOURCE: need diagram for compressor terminals .need to

Good day,
I don't know the terminal layout you asked for but here is a method that will work on any compressor anytime.
Be aware equipment manufacturers will use more than one brand of compressor on a given model.

You will need an ohm meter that has a scale that can be set to a
0 to 20 ohms or near there.
Hold the 2 probes together and set until you get a reading of 0 ohms.

The compressor will have 3 terminals
Take the 2 probes and keep checking between 2 at a time until your sure you get the highest resistance reading.
The terminal your not on is COMMON. record it.

Next put one terminal of the meter on that common terminal, and the other on one of the others one at a time.
The terminal between common and the terminal that gives you the lowest reading is RUN.
The one left is obviously start.

For example. You keep taking readings 2 at a time from all the terminals and the highest reading is 12 ohms. Then the one your not on is Common.
You put one probe on the common terminal and check with the other probe both terminals. One reads 10 ohms, and the other 2 ohms. The terminal that reads 2 ohms is Run. The one that reads 10 ohms is start.

Diagram for hooking compressor to compacitor on Maytag 6000 btu air conditioner


If you have a dual capacitor, which has 3 posts, C - goes to Run on the compressor. Herm goes to start on the compressor. If you have a single capacitor Run from the compressor goes to the terminal on the capacitor that has a wire coming from one side of the contactor. The start wire goes to the other terminal on the capacitor without another wire attached to it.

Need wiring diagram on compesor


The compressor has three terminals, Common, Start and Run.... The terminals read left to right, top to bottom just like pages in a book. So if theres one on top, its Common then Start will be the first one in the next row. If theres two on top, it'll be Common on the left and Start on the right then Run on the bottom.

The run capacitor wires in between Start and Run and line voltage is applied to Common and Run.

Air compressor on Heil air conditioner is humming but not kicking in


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.

I have a ckL 36-1L CONDENSER UNIT BY GOODMAN I NEED A PICTUR E DIAGRAM TO WIRE UP THE WIRES FROM THE COMPRESSOR TO THE CAPACITOR TO THE CONTACTOR TO THE 24VOLT T-STAT WIRES TO MAKE THE CONDENSER UNIT...


Hi, I can tell you how to wire it, but no diagram. Take the common wire from the compressor, look on the terminal cover or straight at the terminals and you will see C, R, and S. Wire colors vary. C is common on the capacitor, R goes to herm on the capacitor, and S goes to the load side of the contactor, or outlet side, to one of the un- used terminals on either side of 220 volts. That takes care of compressor, R, Run, S, Start, and C, for Common. Low voltage wires will be 2 -18gauge wires coming off each side of the coil on the contactor, connected to the 2-wires coming from your indoor unit, 24 volts. Your off and running unless its off on low pressure switch, and then it will start when you start adding freon.I hope I have been of help to you.

LG LHD30 the compressor does not cycle on


Compressor won’t Start
The Main reasons that this will happen
1 - A bad run capacitor (silver or metal capacitor)
It’s either shorted, grounded or open.
If it’s shorted a lot of times it will bulge out, (sometimes slightly)
2 - A bad start kit ( plastic capacitor and Relay connected to it )
The capacitor is either shorted or open
The relay either has an open coil between terminals #1 and #5
Or the relay is stuck.
Any time you change the capacitor or relay you should change
the other, especially if they are over a year old.
3 - A loose, burnt or disconnected wire
4 - Wired wrong
5 Compressor is open (windings burnt open)
6 Low on charge not getting enough cooling back to compressor, (Feel top of compressor to see if it’s hot it shouldn‘t be)
7 Some compressors have a black plastic overload under the compressor cap which could be bad.

What terminal on the capacitor gets the blue wire from the run terminal on the compressor? Does it go in the terminal with the white wire or the blue wire?


Follow the start wire from the compressor to the capacitor, the run wire will go to the opposite side.
For instance if the white wire is the start wire on your compressor then the run wire will go to blue wire and vice versa.

No cold air


  1. The filter could be dirty This is the most probable cause and, of course, the easiest to check and correct.
  2. The evaporator coil face could be coated with lint,dirt, etc.Dirt or lint on the coil will restrict the flow of air through the coil and the unit must be removed from the recreational vehicle and the soil must be thoroughly cleaned with strong detergent (Coil X,Calclean, etc.) and water. Be sure to protect the fan motor and electrical controls during cleaning by covering them with polyethylene sheet. After the system is cleaned, allow it to thoroughly dry for several hours (before turning it on) to prevent electrical shorts.Before system is put back into operation, be sure the filter is properly installed to prevent recurrence of dirty coil.
  3. No compressor (Does not try to start).The compressor does not run and it does not hum.
    1.The selector switch may be open.
    2. Thermostat may be open.
    3. Overload switch may be open.
    4. Compressor winding may be open.
  4. Selector Switch
  5. Thermostat
  6. Low Voltage
  7. Overload
  8. Compressor
  9. Wiring (Mis-wired)
  10. PTCR or Potential Relay
  11. Start Capacitor
  12. Run Capacitor
To check the selector switch, remove wires from the terminals
and rotate the switch to the proper position and read
continuity as follows:
Terminals Switch Position
L-1-3 Lo Heat
L-1 Lo Fan
L-2 Hi Fan
L-1-4 Lo Cool
L-2-4 Hi Cool


Compressor Motor
The compressor motor is located inside the hermetic
compressor housing and therefore not accessible for service or
visual observation in the field. However, the motor winding
condition can be analyzed by using an ohm meter. Be sure to
remove all the leads from the compressor terminals before
making this check.
1) If the resistance between any two terminals is 0
ohms, the motor windings are shorted.
2) If the resistance between any terminal and the
compressor housing is anything but infinity, the
winding is grounded.
3) If the resistance between any two terminals is
infinity, the winding is open.
On a good compressor, the highest resistance will be between
the R (run) and S (start) terminals. The lowest resistance will
be between the C (common) and R (run) terminals. The
intermediate resistance will be between the C (common) and
S (start) terminals. Notice that compressors have the
identification of the terminals marked on either the terminal
cover or on the compressor housing.

Capacitor Check
There are several capacitor test devices available. The ohm
meter is one of them. The ohm meter cannot verify a
capacitors MFD (microfarrad) value. However, the following
procedures will show you how to use an ohm meter to
determine if the capacitor is good, open, shorted or grounded.
Before testing any capacitor, always perform the following
procedure:
* This test must be done with a analog type meter.
a) Disconnect all electrical power to the air conditioner.
b) Discharge the capacitor with a 20,000 ohm (approx.
3 watt) resistor or larger.
c) You may discharge capacitors with a standard volt
meter if you use a scale over 500 volts and touch the
leads (one lead to each side of the capacitor). The
volt meter will discharge the capacitor.
d) Identify and disconnect the wiring from the
capacitor.
e) Set and zero the ohm meter on the “highest” scale.
When testing for a good, open or shorted capacitor,
perform the following checks: Place the ohm meter
leads across the capacitor terminals (one lead on
each terminal) and perform a continuity test. Then
observe the action of the meter needle or indicator.
Reverse the leads and test again. The result should
be the same. Note: If the capacitor had not been
properly discharged, a false reading could be
indicated on the first test. Always test several times
(reversing the leads with each test). This will verify
the capacitors condition.
Good Capacitor
If the capacitor is good, the indicator will move from infinity
(the left side), towards zero ohms and slowly return back to
infinity. Reverse the leads and test again. The result should
be the same.

Start Capacitor
Most models use a start capacitor and a start relay to give the
compressor high starting torque. The compressor will,
therefore, start against normal pressure difference (head
pressure minus suction pressure) even when shut down for a
short period of time. The start relay will disconnect the start
capacitor when the motor reaches approximately 75%
running speed.
Start (Potential) Relay
The start relay consists of –
1) Normally closed contacts internally between
terminals #1 and #2 which switch in the start
capacitor in parallel to the run capacitor during shut
down and then switch out the start capacitor when
the motor reaches approximately 75% normal
running speed.
2) A high voltage coil internally between terminals #5
and #2 to actuate the contacts. The coil is too weak
on line voltage to actuate the contacts, but it is
connected in series with the start winding and it gets
the generated voltage of the start winding portion of
the compressor motor. This generated voltage is
much higher than line voltage and varies with the
speed of the motor. Therefore, since the relay is
designed to open the contacts at 75% of normal
running voltage (measured between terminals #5 and
#2), the contacts will open (thus disconnect the start
capacitor) at approximately 75% of normal running
speed.
(B) Positive Temperature Coefficient Resistor
(Commonly Known As PTCR Start
Device)
The resistor acts like a potential relay in that it takes the start
capacitor out of the start circuit, but uses resistance of
electrical flow (back EMF from compressor) instead of
opening a set of contacts. The service person should be careful
handling the resistors. They will be hot during operation (up
to 160 degrees F). The air conditioner needs to be off for 3-5
minutes during cycle time and when servicing to let the
resistor cool down.

Need wiring diagram for Ruud Model UPCA-048jas


The wiring on these is pretty straight forward

Basically a contactor, either DPST or DPDT, depending. Input power connects here.

Compressor C terminal connects to one side. R terminal connects to the other. 1 terminal of the run capacitor connects to the terminal with the R terminal of compressor. The other side of run capacitor hooks to S terminal of compressor. One wire of condensor fan hooks with compressor R terminal, the other condensor fan lead hooks with compressor C terminal.

Only things missing from all this is a hard start kit and crankcase heater. Let me know if you want to know how to hook those up.
