In many cases, a compressor winding that touches another surface and draws excessive current will result in a shorted to ground condition. Bert starts his diagnostic process by resetting the breaker and seeing how quickly it trips. It trips immediately, indicating a significant short. Before working on a unit, he confirms that the power is off ...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 ...Wait! Before concluding it's a grounded out compressor please allow me to go through this with you. I find 50megohms from any winding to case is normal. That's a very high resistance for this application. The capacitance of the motor windings to the stator is enough to read 50megohms. 1) Unplug or remove the connections at the compressor.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 …It isn't useless. It may not be something you use every day, but I have needed to ohm out a motor or compressor a handful of times, and it got me out of a pinch. So, here it goes: The lowest ohm reading is between Common and Run; The middle ohm reading is between Common and Start; The highest ohm reading is between Start and Run

If a compressor is defective and out of service, your HVAC system will only blow warm air. In commercial HVAC applications, diagnosing AC compressors can be complex for inexperienced technicians. A type of compressor in particular that causes many questions is a 3 phase AC compressor.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.Refrigeration recip compressor running backwards. I recently went to a restaurant to work on a reach in cooler, 115v. The compressor seems to be running in reverse. The evaporator coil is hot and the condenser coil is icing up. I changed the start components after verifying correct common, start and run leads by ohming out the compressor.3 phase motor winding resistance values, Using Ohm meter: Disconnect all power from the system. Check all three wires singly T1, T2, T3 (three phases) to the ground wire. Readings should be infinite.

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.1. Tested the Compressor (no inverter) with Multi-Meter \- Turn Power OFF \- Remove start relay and overload from the compressor \- Set dial to ohms a) Start with red one on top and black one on bottom right Should get around 4-6 we get: 4 b) Now try red one on top and black one on bottom left Should get around 4-6 we get: 6Turn 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 system. Next, observe at what point in the sequence of operation the amperage spikes and/or the fuse blows.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.The compressor is an electrical motor connected to a precision pump. The pump has to be lubricated by sufficient refrigerant (Freon or substitutes). If a compressor seizes, it may burn out the electrical motor, causing the electrical windings to short out. Long story short, a failed compressor may be a reason for system replacement.

Testing your compressor will alleviate a lot of uncertainty you may have in determining if your compressor is operation/functioning properly.If the pins aren’t marked, set the multi meter’s function switch to the R x 1 scale, and find the 2 pins that give the highest reading – those will be your Run and Start winding pins. The pin left over is the Common pin. Use a multimeter to test your compressor. If the meter L.C.D displays ‘O.L’ when checking between any 2 of the pins ...Restart the compressor Connect liquid gauge to the hot gas line and then the liquid line, the readings should be similar.

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. >I try and stay away from the compressor lugs themselves because those terminals can actually blow out. Connect your AC compressor clutch to a 12-volt battery to see if it engages. Connect your negative, or black battery cable with the grounded contact in the compressor. Then, attach the black wire to the negative side of the battery. Connect the positive, or red wire, to the positive side of the battery.
