Ohming out a compressor.

The first thing to do before testing the windings of the motor is to remove the links linking terminals W2U2V2 and the disconnect the motor from supply (L1, L2, L3). A multimeter terminals placed across this matrix of terminals will indicate the following readings for a good 3 phase motor: (a) Terminals W1W2, U1U2, V1V2 will indicate continuity ...Apr 29, 2014 · Join Date Apr 2014 Location Riverside Ca Posts 89 Post Likes Likes (Given) 0 Likes (Received) 0 Dislikes (Given) 0 Dislikes (Received) 0 Insert the multimeter probes into the sockets of the stator. The reading should be between 0.2Ω to 0.5Ω. If the reading is not within this range, or if the reading is infinity, it is a clear indication that the stator is faulty. We advise you to read your vehicle’s service manual to know the safe readings. 2.Turn off the service disconnect, go to the thermostat and turn all modes to off, place an ammeter on the 24V power line coming out of the transformer secondary, and then turn on the high-voltage power to the …

Look for the largest deflection between lead #3 and the other two wires. The wire with the largest deflection will be lead #6 and the other one lead #8. Last step is to determine which is #4 and #9.So here are 2 diagrams of a condenser fan motor wired first in a 4 wire configuration and next as a 3 wire configuration. As you will see, the "white" wire and the "brown/white" wire are connected internally and are really the same input into the main winding and capacitor. NOTE: Please don't be confused by OEM wire colors.This includes electrical devices such as motors, switches, wires, etc., and even the human body. This property of resistance is measured in units called “ohms, named after German physicist Georg Simon Ohm. It can be measured with a standard digital multimeter. Electrical resistance resists the flow of electric current.

Don’t be fooled by false readings when ohming out a scroll compressor. Between common and start, as well as common and run, you have an inherent protector that will open on high amps or high heat. Until it cools down, you will read 0 ohms, but you will get a reading from start to run. I have some examples of a few electrical issues below:

In a single-phase, 240V HVAC system, the surge protector is connected to the two “hot” voltage legs, L1 and L2, and to the ground terminal. Under normal conditions, the surge protector allows only the tiniest amount of current to trickle to ground. But when a spike in voltage occurs, resistance drops almost instantaneously.

Unplug the MAF electrical connector. Visually inspect the electrical connector and terminal for dirt or damage. Gently pull on the wires to check for tightness. A dirty, burnt, contaminated, or loose wire will interfere with the sensor signals. Set your digital meter at or close to 20 Volts DC (direct current).Next. Wirenuting · #2 · Mar 30, 2018. Samjon said: Hi. I was working on a Roof top unit and checking the resistance of the compressor (3 Phase) windings. L1/L2= 2ohm, L2/L3= 2 ohm, L1/L3= 1.2 ohm. No short to ground. I was told in 3 phase motors/compressors that all windings should be equal, This would be a short between L1 and L2 windings.Table of Contents. 1 Motor Ohm Values Chart.; 2 it’s a very easy way here to Know The Motor Ohm Values Chart & set up the coil size of the motor. you can get it as an example and do it with all types of motors like single-phase and three-phase. so the friend keeps watch and enjoy it.; 3 3 Phase Motor Winding; 4 3 Phase Motor Winding Resistance …If you turn on your air conditioner and you notice a louder than normal noise, your compressor could be starting to go bad. Your compressor could be making noises for a couple of different reasons, including loose bearings or a leaking bearing. Loose bearings typically make a grinding noise, and leaking bearings make a squealing noise.Unplug the MAF electrical connector. Visually inspect the electrical connector and terminal for dirt or damage. Gently pull on the wires to check for tightness. A dirty, burnt, contaminated, or loose wire will interfere with the sensor signals. Set your digital meter at or close to 20 Volts DC (direct current).A key test that needs carrying out is checking the external power level. Whilst this is not located on the motor itself it is closely linked to how it operates and could cause problems if it is at a wrong level. You should always check the level of the incoming power supply and ensure that it is in spec for the operating voltage of the motor ...

Loose bearings typically make a grinding noise, and leaking bearings make a squealing noise.

Testing the Compressor A three phase compressor will have three terminals. T1 – T2 – T3. Remove the wiring from the three terminals before testing. Set your multimeter to read ohms. Check the compressor for resistance to ground. With the wiring removed from the compressor terminals, test the resistance of each terminal to ground.

For single phase compressor,normally it have 3 connection for winding.It is common ( C ) ,Starting winding ( S ) and Running winding ( R ).We can determine this 3 connection using a multimeter.We measure the ohm value of 3 connection to confirm the winding. Measure from all of 3 connection and write down the ohm value,example :-.Jan 14, 2020 · Take a photo of the compressor wiring for future reference. Remove 3 wires (Common - Start - Run) and set the DMM to the lowest Ohm Value (Ω). Record the resistance values for the following: Common (C) - Start (S) Common (C) - Run (R) Start (S) - Run (R) On an operational compressor you may see readings as follows: Set your multimeter to Ohms. Start by completely disconnecting the spindle motor from all power sources. Check each wire, including T1, T2, T3 and the ground wire. If the reading is infinite, your motor should be fine. If you get a zero reading or any continuity reading, you have either a motor problem or a cable problem.Follow the troubleshooting steps above to figure out what the compressor problem is and repair it. Many times, when you hear a loud humming noise coming from a condenser the noise is created by the compressor contactor. If it is too annoying, replace it. AC condenser fan is working but the compressor is not running.I’ll also go over everything that you need to check in your AC condenser—step-by-step. Check the air handler unit. Check for power to the condenser unit. Check the fan capacitor. Shut off power to the condensing unit. Remove the service panel on the condensing unit. Find the fan capacitor. Inspect the fan capacitor.To test the COP ignition coils you do not need an automotive diagnostic scan tool (commonly known as a scanner or scan tool). You do need a few basic tools and these tools won't break the bank. An HEI spark tester.

I usually just do this with the wires at the service panel still connected to the compressor. If I see something screwy, I'll make an effort to check at the terminals themselves.

Three-phase synchronous motors can be purchased with a variety of wiring styles. The most common is nine-wire, but there are also many examples of motors with three, six, or even twelve wires. Of all types, the twelve-wire motor provides the most options for connecting based on voltage and system configuration (wye or delta).
