The EEV sensor will usually not fail completely but will be out of calibration and produce an incorrect temperature reading which results in an incorrect super heat control. Overheated thermal bulbs (TXV) will usually shut the expansion valve on start up.

20040728· The controller may open the EEV too much and cause an overcooling condition. The sensors connected to the refrigeration system and wired to the controller will sense this overcooling condition and feed this information to the electronic controller and the EEV. This will cause the step motor to move in the closing direction and close the valve more. The feedback loop is shown in Figure 3.

When the solenoid valve is deenergized (closed), pressure around the piston is discharged and spring force ensures that the scrolls are loaded. When the solenoid valve is energized (open), discharge gas in the modulation chamber is relieved to low pressure and compressor is unloaded. The DCM program uses a 12 second duty cycle. This indicates that there is an on/off cycle every 12 seconds. If ...
