Abstract:
A method includes cycling an electronic evaporator pressure regulator valve fluidly coupled to a refrigeration circuit to regulate flow through the electronic evaporator pressure regulator valve and sensing a current drawn by the electronic evaporator pressure regulator valve during cycling of the electronic evaporator pressure regulator valve. The method further includes determining a valve condition of the electronic evaporator pressure regulator valve based on the sensing.
