If you open up the manual drain, there should only a little water be coming out. If you have a compressed air dryer, check the dewpoint. Compressor overload relay trips Check the current draw with a current clamp meter. If the motor draws exeessive current: Try to turn the compressor by hand.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.Step 4: Insert the compression connector into the cavity of the coaxial compression tool. Press the handle together till the ratchet system loosens. And you can remove the terminated compression connector. Step 5: With the slide cutter, trim the conductor at the center to give a secure fit of the compression connector on the coaxial cableUsing a good multimeter set on ohms, remove the compressor terminal cover with the unit off.
