I ended up replacing the MO BOard and I got the compressor to run. This has to be present for the inverter to do its job. 2 Link to comment . Let the inverter start and watch the LED's. Disconnect the compressor lead from the compressor terminals. I have a direct devise i got from G.E 30 years ago make by ROBINAIR that iforgot to give back to them 30 YEARS ago and its made just like your diagram.Comes very handy. Here we show you how to test you relay on the compressor and for a short in the compressor when the compressor won't come on but everything else is running. Replace the front panel of the LCD screen and its retaining screws. Learn to test your LCD screen's inverter board. My question is this; is it possible to test the inverter board without the indoor unit? UNPLUG THE LAPTOPS INVERTER AND PLUG IN OUR KNOWN GOOD INVERTER. A few years ago it was rare that I got an email asking the question about how inverters work but now I have noticed the question coming more and more so I wanted to write an article to explain how inverters work. Only 2 left in stock - order soon. Turn on the LCD screen and wait for the Multimeter to take a reading. If you see the current draw jump to say 4 amps (typical LR current in these inverter compressors) and then drop off, keep watching. It was not a steady reading like the dc reading you were getting when I watched your informational video . If you were to measure the resistance of the start winding and the main (or run) winding, you would find that the start winding has a higher resistance than the run winding. Shipping, Returns and Payments Details See details. 3. Touch test probe to shunted compressor terminals. MASTER SAMURAI TECH I was able to barely here it running but it was sounding like it was running. Answer Hello Reynaldo, the compressor's inverter board is getting the correct run signal (4vdc), using a multimeter check the compressor's windings, they should all match,with no open/short/ground, if ok then replace the inverter board.241577505. the schematics are not clear which line is the 5 volt dc (vcc) input. 2-3-Day Delivery-200D5948P008 GE Embraco Refrigerator Compressor Inverter Board 200D5948P008 IMPORTANT: Some models are required to use the old wire connectors and harness, EASY JOB just remove one screw ONLY FIT IN SERIALS: 200D5948P001, 200D5948P002, 200D5948P003, 200D5948P004, 200D5948P005, 200D5948P006,200D5948P007 Buy It Now. The signal voltage at the inverter should be equal to … More details on compressor test cords here: http://appliantology.org/blog/1/entry-669-rigging-and-using-a-compressor-test-cord-to-manually-operate-a-compressor/. Unfortunately, there's no way to check this other that by testing the resistance of the three windings, which you did. In the conventional compressor technology that's been around for decades, the compressor has a start winding to help kick things off and a main (or run) winding that keeps the compressor going after it's started. Turn off your LCD screen and disconnect your LCD's power cable from the nearest electrical outlet. So I checked the voltage coming from the Main Control board at the J15 plug (which controls the inverter). Inverter Board - Whirlpool W10629033 - This is an inverter board for a compressor. In the hermetic type, it can either be a scroll or reciprocating compressor. Unplug the compressor and you'll see 3 pins on the side of the compressor. $190.00 $ 190. This is a simple data connections check and does not need to be an inverter driven system. Your LCD screen's inverter board is one of the most important components of your LCD screen assembly. Turn on your Multimeter device and enable "DC Mode" on the Multimeter. One easy and important way to troubleshoot your LCD screen's inverter is by testing it to see if it is sending and receiving power. This is partly how the Danfoss Optyma plus inverter condensing unit works, it has a very clever control loop which is measuring the cooling load and then changes the speed of the motor, which changes the speed of the scroll compressor and that increases or decreases the cooling capacity to match the load and achieve precise temperature control as well as energy savings. That is the Inverter Board that is in a gray plastic box that is attached to the side of the compressor (on the Monogram). Disconnect the compressor from the inverter board, then check all 3 windings for continuity. Quantity : Buy It Now. Disconnect the compressor from the inverter board, then check all 3 windings for continuity. We will not consider the design of such an installation from "a" to "I", but only to identify the main positions. Now i am thinking that I mis diagnosed the issue and it needs a mother board instead. A wide variety of inverter compressor with control board options are available to you, There are 231 suppliers who sells inverter compressor with control board on Alibaba.com, mainly located in Asia. Could you tell me how the Phase Rotation tester is used on the inverter to check it. Unplug the compressor and you'll see 3 pins on the side of the compressor. - Connect your amp meter around one of the wires supplying 120 VAC to the inverter board (doesn't matter which one). If the compressor windings check good, this is not diagnostically conclusive that the compressor itself is good. 9v battery 2. I can only surmise but the typical HVAC thermostat is only a part of the control as we need to know when to modulate the compressor and the fan motor down to a lower RPM or speed based on demand. Free returns. In this case, if the MOBO really was bad, then the phase rotation tester wouldn't have shown you anything new because the inverter wasn't putting anything out apparently due to a bad PWM signal from the MOBO. Current test standards allow inverter AC (IAC) manufacturers to “lock” the compressor speed for a desired “rated” capacity. We have to have a PCB kit which will make the voltage according to this inverter compressor. It's possible you're dealing with a bad compressor. wishfultech. I already replaced - 3 thermisters (1 in FZ and 2 in FF) - the mother board (main board) The compressor still dead silent. Now you have to check the inverter board itself. Either way, the go-to document for this is the schematic. All three windings should have the exact same resistance. It's really easy. I checked the J15 connector at the mother board and at the connection going into the inverter board for the out going DC voltage and I was reading a fluctuating DC voltage from 4.2 to 5.6 , 4.5 to 5.4 . I was not getting the 5 volts dc (VCC) coming from the main board up top. CH23 Inverter dc voltage low. You will need an Inverter tester, Turn off the power. For one thing, inverter compressors use a special three-phase voltage produced by a special control board called an inverter. OTOH, if you're getting both of these input voltages to the inverter and the compressor isn't running (and you've already checked the compressor winding resistances), then you need to do this next test: 2. 4.4 out of 5 stars 25 ratings. The new inverter compressors ain't like the old skool compressors used in yo momma's beer cooler. CH24 Splits and Multi Splits = High or low pressure trip. In hindi and Urdu . Refer to page 64. either. I then went to the compressor unplugged the inverter and measured the resistance between each of the two pins. 00. If both those exist you test your compressor for proper resistance and be sure it's not shorted. FREE Shipping. Thanks for getting back . There are some pins denoted TEST/SS pins but could not get a useful output when checking the U,V,W outputs with a differential probe. 00. is a runnable frequency) with a 12 volt transformer and a manual compressor test box. GE Refrigerator Compressor Inverter Control Board AP5669522 Brand: universal part same day. Whats strange though is I could barely feel or hear the compressor running when it was and one of the ways I could definitely tell it was running was to put the tip of a long Philips screw driver to the compressor tank and then the handle end to my ear lobe. There are two different tests you can do on the inverter board to see if it's good or not: An Inverter board will have two different input voltages: - 4 to 6 VDC control voltage from the main control board (or Muthaboard-- a completely separate circuit board in the refrigerator). check the resistances in all three windings to rule out an open winding. I have a direct devise i got from G.E 30 years ago make by ROBINAIR that iforgot to give back to them 30 YEARS ago and its made just like your diagram.Comes very handy. The inverter board is a small circuit board inside your LCD screen that supplies power to your LCD's backlight device, which lights up your LCD screen and allows you to view images, graphics and videos on your screen. developments in variable-speed compressor (inverter) operation. When checking inverter voltage output, connect the test-meter leads to any 2 of the 3 compressor lead wires. They're like voltage checkers but with extra leads for two other voltages (phases). Don't try that on these inverter compressors because you'll permanently break it. But you have to troubleshoot them differently from the old skool compressors. If so, the compressor could be tested (assuming 60 Hz. IPM continuity check. Check the resistance of the BLDC motor's windings. But you can (and should!) The inverter board is a small circuit board inside your LCD screen that supplies power to your LCD's backlight device, which lights up your LCD screen and allows you to view images, graphics and videos on your screen. AC inverter board can be checked by connecting 3 indentical and strong enough light bulbs in delta configuration and than measuring voltages and amperages wich Inverter board is producing. Current test standards allow inverter AC (IAC) manufacturers to “lock” the compressor speed for a desired “rated” capacity. Once they're up and running, these old skool, compressors run at the same speed and move the same amount of refrigerant vapor per minute. So, let's summarize the old skool compressors: - has two windings, a start and a run winding, which are physically different windings and have different resistances; the start winding has higher resistance than the run winding, - runs off standard 120vac household power, - uses a start relay to initially power the start winding and then take it out of the circuit after the compressor is up and running, - can rig up a test cord to directly power the compressor, - are constant capacity and speed machines. it was fluctuating back and forth from 4.2 to 5.6 DC volts. You can't test the main control board but you can test the compressor. I would like to know how to test: - Voltage from the J15 to the Inverter. $205.00 $ 205. If the inverter board was replaced and the compressor still wont' start, either your main control board has failed and needs to be replaced, or the compressor is bad. Remove the plug that attaches to the compressor and then with the power on check your voltage coming to the compressor. Let us look at the control circuity for the DC compressor that takes its supply from a single phase power supply. No Check if the outdoor fan runs properly or the outdoor unit ventilation is good. One washer I was nervous about diagnosing it when I got their and dont you know the guy was behind me watching every move I made on top of that. 3. no video to the lcd screen. If you can fix one, you can fix the other. We have placed cookies on your device to help make this website better. Other refrigerators have a similar board located inside a metal panel on the back of the refrigerator - youtube has plenty of examples that show the remove and replacement of such boards. At the inverter itself, you would test for 120 Vac getting to the inverter. The inverter is the brains of the refrigerator. Also, there are inverter checkers, but they are good only for checking output for all 6 power transistors (you can do that with universal meter also). The electronics control is the most complicated part of a DC inverter system hence making it one of the most costly component of the air conditioner, the other part being the compressor. From the outside, the inverter box looks like this: Whirlpool inverter box. $8.14 shipping. If your LCD screen is part of a laptop, shut down your computer and then disconnect the power cable and all peripheral devices from the computer.
