You can diagnose problems with your compressor by using a multimeter, or a device that can measure volts, amps, and ohms. Okay, so let's say the compressor windings check good but it's not running. I replaced the inverter board at this point thinking it was the problem and after installing a new inverter board the refridgerator issue was still the same and the compressor was still not working. As for the technology, don't be intimidated by it! For the Samurai shall reveal the truth unto thee, and the truth shall set thee free. Typical specs are 80 to 230 VAC with the frequency ranging anywhere from 57 to 104 Hz. I will pick one up as you suggested Samurai. This section generates 3 phase voltage supply to the DC compressor motor. If the start relay fails, the compressor will sit there trying but failing to start and drawing locked rotor (LR) current. As for the technology, don't be intimidated by it! 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. The speed of the compressor motor can be varied by using the variable frequency drive. It's really easy. They can't work "harder," just longer. Could you tell me how the Phase Rotation tester is used on the inverter to check it.
If you can fix one, you can fix the other. The AC compressor requires oil to lubricate the unit and to keep the piston and other moving parts from seizing. I am just not sure how to use it. The rotating magnetic field of the stator pulls the rotor around with the rotor trying to keep up with the rotating field. A common troubleshooting technique with these old skool compressors is to rig up a test cord and manually power the compressor to see if it'll run. 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. If your AC isn’t working, there’s a good chance that a faulty compressor could be the culprit. How to Check If Your Air Conditioner Needs Freon.
Here's the replacement inverter board I used to fix this refrigerator: Excellent vid, Samurai! In both cases, the motor has three windings with all the exact same resistance. But you can (and should!)
Unfortunately, there's no way to check this other that by testing the resistance of the three windings, which you did. - cannot directly power the compressor (well, you Remember how a common troubleshooting trick with the old skool compressors is to power it directly with a test cord and see if it starts? But you have to troubleshoot them differently from the old skool compressors. If the compressor fails to start, the inverter will timeout for 8 minutes and then try again. Any body have any thoughts on this issue.Good troubleshooting, Darren! It was not a steady reading like the dc reading you were getting when I watched your informational video . The new inverter compressors ain't like the old skool compressors used in yo momma's beer cooler. I'm not sure if these variable speed compressors always run this quit but it did. This design is one of the conventional ways of driving a 3-phase motor in a compressor.In a DC brushless motor used in the DC inverter air conditioner or heatpump, the rotor of the motor is constructed using permanent magnets with windings on the stator. I was able to barely here it running but it was sounding like it was running. If the compressor fails to start, the inverter will timeout for 8 minutes and then try again. - 4 to 6 VDC control voltage from the main control board (or Muthaboard-- a completely separate circuit board in the refrigerator) Fuggetabout 120 VAC, 60 Hz line voltage. BTW, the technology used in these variable capacity compressor (VCC) systems is the exact same technology used in front load washers: and inverter board (variously called a "speed control board" or a "motor control unit") that makes a 3-phase voltage to control a special type of motor. check the resistances in all three windings to rule out an open winding.
I think if I remember correctly it was the MI3 #2 and #3 pin connections. Both the amplitude (amount) and frequency of the input voltage will vary. If the resistances vary from each other by as much as a 1 ohm, the compressor will not run correctly. Troubleshooting Inverter Compressor Systems. But you can (and should!) - Disconnect the 120 VAC power supply from the inverter board. Both the amplitude (amount) and frequency of the input voltage will vary. Besides, if the refrigerant makes way to the external unit, it could damage the compressor beyond repair. All that current makes heat, lots of heat.
I was not getting the 5 volts dc (VCC) coming from the main board up top. I will pick one up as you suggested Samurai. If you're missing one of these voltages, the inverter board can't run the compressor. As for the technology, don't be intimidated by it! It's really easy. The frequency will vary according to how fast the motherboard wants to the compressor to run. Once you determine what the problem is, contact a heating and air specialist or an automotive mechanic to get the problem resolved.Before you check your home's AC compressor for damage, shut off the power so you don't shock yourself. Okay, so let's say the compressor windings check good but it's not running. Check the manufacturer's spec for what that exact resistance reading should be. I am just not sure how to use it. All three windings should have the exact same resistance.
- have three windings, not just two; all three windings have the exact same resistance Now you have to check the inverter board itself.
FL washers and VCC fridges use the exact same technology. When cooling or heating is needed immediately, the motor will turn at the highest speed.
