How to Check Compressor or PCB Fault in AC ? Learn Professional Testing Methods in AC Repairing Course at Multitech Institute ACRepairing course | AC Repairing institute | AC Repairing course in Delhi | AC PCB Board | Multitech Institute 🔹 Step 1: Check Output Voltage from PCB (Multimeter) 👉 Measure voltage on compressor output terminals. ✔ If no voltage = PCB Problem ✔ If voltage is present = Check compressor 🔹 Step 2: Compressor Coil Resistance (Multimeter) 👉 Measure resistance between R-S

To check an compressor, inspect for unusual noise or leaks. Use a multimeter to test electrical continuity and measure voltage. Check the capacitor and overload protector. Ensure the compressor is not shorted or grounded. If it's not running or cooling, it may need repair or replacement. #ACCompressorCheck #HVACTips #CoolingSystem #ACTroubleshooting #CompressorTest #ApplianceRepair #HVACBasics #ACRepair #TechGuide #MultimeterTesting #careskillsacademy #acrepairingcourse Contact Us:- 9319887726 F
