I would not suggest "guessing" at anything. Recovering the refrigerant (using appropriate equipment) and then removing the line to the receiver / drier to see if there is any metal in the orifice tube would be one way to check for debris that is "guessed" at. Checking system pressures to see if they are abnormally high due to debris would be another way, using a set of gauges or a proper R134A refrigerant station machine. Electrical testing of the system may be required to ensure the cycle switch is operating properly. Before guessing, spend a few dollars on a competent diagnostic test that can save you thousands of dollars in the long run.
