A commercial refrigerator compressor may draw up to 12 amps. If your compressor's air intake filter is clogged with dirt and dust, it can strain the motor, causing it to draw more amperage than normal. If the circuit is restricted, repair it and . The suction valve is located on the evaporators top. Emglo compressor - tools - by owner - sale The evaporator draws in the refrigerant, which is then emitted to the condenser. They will usually stamp the rated load amps (RLA) of the compressor. Other compressor motor models and brands will have different, if generally similar by order of magnitude amperage draw numbers. How to Protect Your Air Conditioner From Voltage Drops and Power Surges The air compressor can use a cigarette lighter style plug. The pressure load will fluctuate up and down depending on such things as the evaporator load and ambient temperature. How to check Amps on a Compressor: Low Amp Draw Low amp draw is caused by the reduced refrigerant flow rate through the compressor. Liquid backed up in the condenser from the overcharge of refrigerant will flood some of the condensers internal volume at its bottom, causing high head pressures. This can be caused by a low supply voltage, resulting in the motor drawing in more current in an attempt to maintain its torque. We read 43 amps on our amperage meter and 230 V at the compressor terminals. Obviously it would be increased, which means the motor would have to work harder. There is an inverse correlation between the two: As . The running or operating amperage of a refrigeration or air conditioning compressor is directly related to the load put on the compressor motor. Condenser Short Cycling 10 Possible Causes. You cannot size a breaker up to this number, however. Contact him at tomczykjohn@gmail.com. You can identify the suction side of the compressor if you have a fundamental understanding of your appliances refrigeration process. In this way,what causes low amp draw on a compressor? Polymerization is where the lubricants molecules start to combine into larger and larger molecules. If it was directly off the AC breaker hot wire then 25.3 seems a bit high.
