I had a look at the data sheet of the compressor (NJ2212GK) and the resistance rating for the start winding is 7.25 ohms, the rated resistance value for the run winding is 1.95 ohms. If the megger reads a resistance under 1 (1,000 ohms) on your meter after the initial 60-second interval, the cable has failed and the cable should be removed. A pressure relief valve is installed on the compressor to relieve excessive high-pressure buildup (450 psi and above) and prevent damage to the compressor and other A/C components. PTC Danfoss 103N0003 - 115V (originally white ceramic, top half looking rather brown now) plugs onto the compressor and applies 6.9 Ohms (cold) across the compressor pins that measure 17.9 Ohms. Then flow the next step. So, when the compressor is defective, the cooling system will not function appropriately, causing the refrigerator to start warming up. Unclip the black plastic cover at the left-hand side of the compressor, and wiggle it out. Similarly, if it is not running at all, it is an indication that the compressor is faulty. In this 6-minute video, Doug Smiley, Technical Training Manager, shows how to read ohms on a compressor. Your email address will not be published. If the megger reads a resistance between 1-1.25 on your meter, then the cable passes. if that shows different results then the compressor winding is burned or crossed. It's either grounded or not. This code indicates something is wrong with the condenser fan; the feedback time from the fan is below 65 seconds. When this speed goes higher than normal, the compressor will produce either a banging, knocking, or buzzing noise. What Is the Linear Compressor In an LG Refrigerator? Required fields are marked *. Spin it and if it does not spin freely, it is most likely defective and the reason the compressor overheats. If the compressor is shorted, you will need to recover the refrigerant anyway, so this gives you a head start on the compressor changeout. We are taught that resistive loads (loads that create light and heat) are much simpler. Test Compressor by Multimeter. This can be due to excessive loads, poor airflow or lack of superheat. The compressor should get a 120V AC from the motherboard. Obstructing the cooling vents. Now set your multimeter knob on connectivity text or Ohm. The thermostat ranges from 0-9. Why do we use an overload protector with a compressor? Overloading the drawers and shelves may stop the refrigerator door from closing well. So if you are still in doubt, check the manual. This incredibly amazing. With the contactor pulled in I have 234 volt on breaker at panel box, 118 volt at each leg to ground at unit and disconnect, with contactor disconnected I have 234 volt at .

We use cookies to ensure that we give you the best experience on our website. The initial start-up in the field is a very critical period for any compressor because all load-bearing surfaces are new and require a short break-in period to carry high loads under adverse conditions. Then they ohm out a residential compressor or other single-phase motor windings for the first time. Beside above, what does a reading of 0 ohms mean? Readings may run from .5 to 100 ohms but should be equal. Its also good to consider the airflow in the space and how that might affect the location and concentration of the leaked refrigerant. This method is good for detecting grounded or open windings and windings that are suspect (resistance too high). The M symbol may appear in the display because the resistance of open (unattached) test leads is very high. So, if you had 2.3 ohms between Common and Start and 1.7 between Common and Run, you should have about 4 ohms between Start and Run. S-C = 450 ohm R-C = 450 ohm S-R = 2 ohm Measuring to ground is goofy too. In the case of a short, the resistance is typically considered to be zero. It is important to take note of the numbers. air compressor. 30 minutes off) and are offered 12 VDC Only. Unplug the appliance and leave it for at least 8 hours before plugging it back in. Now, connect the other two ends of each resistor on each side of the 3-pin sensor. Which is the most sensitive range of ohms? . It depends on the vehicle brand and compressor model. Note that while touching the pins, numbers should not appear on the meter. As you know that in a single-phase fridge or air conditioner compressor we have internally instilled a single-phase motor that consists of two types of winding which we called main winding (ruining winding) and Auxiliary winding (starting winding). , what does a reading of 0 ohms mean when it is faulty checking Windings...
