OPERATION The A/C compressor clutch components provide the means to engage and disengage the A/C compressor … 3 Fluke Corporation Insulation resistance and electrical testing for HVAC compressor motors 6. https://ricksfreeautorepairadvice.com/diagnose-compressor-clutch-coil Now if compressor winding resistance shown the same as I have shown in the identifying compressor example then change your PTC (positive temperature coefficient thermistor) relay and com.. overload protector or capacitor and if still not working then call a professional.Mostly in some compressor … Typically, the resistance of an A/C clutch coil is ~ 2 - 5 Ohms. Compressor Resistance Readings I understand that once you remove the wires from the compressor and take an ohmmeter to the compressor terminals you should get an open circuit between any terminal and the compressor … Measure the temperature of the compressor ter-minals. An air conditioner works by removing heat from the interior of the building and venting it outside. Answer B is correct. Also, since I jumpered the clutch coil directly to the car battery and the clutch plate still did not engage, it leads me to believe it’s a bad coil. On one side of the coil I have 120v. The coil control voltage is 240v. Finally, I tested the resistance of the coil… A replacement coil is $95 at the Honda dealer; a remanufactured Honda compressor complete with clutch and coil … The A/C clutch field coil on the Denso 10S17 A/C compressor is also retained to the front of the compressor using a snap ring (5). An A/C compressor clutch coil is a simple device made of fine windings of wire wrapped into a coil. Figure 1. A reading of 0.00 Ohms indicates that there's a short in the coil windings. Coil resistance outside of this range will not engage or will cause fused circuits to open. There should be a measurable resistance … Since the temperature of the windings cannot be measured directly, the temperature of the compressor … 3) Is the field coil resistance between 2.8 and 4.4 ohms? The field coil on the Visteon HS-!8 compressor is pressed onto the front of the compressor. Yes — Continue with step 4; No — Remove the compressor and return for evaluation. I tested the voltage going to the compressor clutch, and it reads 14v when AC is on, and 0v when it's off- that was my first tip that the clutch coil was the problem. The air conditioning system consists of a compressor, condenser coil, evaporator coil, blower fan, condenser fan, thermostat and related electrical circuitry and tubing. The current drawn is about 17.6 amps, tag says max current is 6.5 amps. Once the wires are disconnected, you can ohm out the wires, plug and compressor as they all require an inspection. The compressor on my Kenmore model 106.54682300 runs for 5 sec and shuts off, comes back on in 2 min and repeats. 4) Is the compressor … The coil in question controls circuit #1 which is a 3 phase compressor of a package AC unit. The evaporator coil … With the multimeter set to R x 1 scale (ohms), measure the resistance between the run and start wires; start and common wires; and run to common wires. Answer C is wrong. A reading of infinity indicates there is an open in the windings. Megohmmeters (meggers) are electrical meters used to check the resistance and condition of the motor windings and the condition of the refrigeration and oil environment around … Next I tested ground continuity from clutch coil to engine block, and it's grounded. Get shopping advice from experts, friends and the community!
