Ohming out a compressor
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.In "What's A 3 Post Solenoid?"

Disconnect old kit if already existing Verify overload corrected Attach Ammeter toYou’re good. Don’t listen to ass hats. Next time pull the disconnect and ohm out the windings. Chances are the compressor is out on overload probably cause the fan took a shit. If the contactor is pulled in you know you have a call and if you got voltage then you know it didn’t pop a fuse. Ohm out the compressor.Upvote. i usually go right to the terminals on the compressor itself. disconnect and mark your wiring. single phase from S to R will be your highest reading. S to C will be second, and R to C will be your lowest. S to C and R to C should equal S to R. 3 phase ohms will all read the same, make sure you put your wires back on the correct ...... compressor not turning on. Your home starts heating up; the kids are getting grumpy; you're handing out glasses of cold lemonade as fast as you can; etc.No, the procedure I was describing, 'ohming out' the windings, will also reveal a 'winding to winding' short, which is a third type of short. If you measure resistance from r to s, for example, and get .4 ohms of resistance, but measure r to c and get 2 ohms, you have a winding to winding short (and it's time to condemn the compressor).Mar 26, 2018 · FIRST STEP: Greg Fox, president, Fox Family Heating and Air Conditioning Inc., Sacramento, California, said his first step is to check and see if the compressor is getting voltage using a multimeter. CHECK THE LINE: “Check the line side of the contactor first,” said Fox. “You want to make sure all the fan and compressor terminals on the ...

2. Confirm the proper input to the transformer. Apply power to the circuitry. Use the DMM in AC mode to measure the transformer primary. If the measurement is less than 80 percent of the expected voltage, the fault could lie in either the transformer or the circuitry providing the primary with power. In that case:Run Winding 243V ÷ 2.6Ω = 93.4A Start Winding 243V ÷ 4.2Ω = 57.85A Well, THAT makes no sense, so they stop using Ohm's law and settle for believing that electricity is magic and Ohm's law is broken. In actuality, Ohm's law does work; it's just that the loads we measure tend to vary and don't all behave in the same way. Inductive Loads
Step 2. Disconnect the refrigerator from power and put one ear to the refrigerator’s side. You should hear the gas gurgling and hissing. If you don’t hear these noises, the gas may be low. But it could also be a fault with the condenser coils, condenser fan, defrost system, compressor, or cap tube.Disconnect or unplug all electrical power to the appliance.
