I have a Franklin Chef PIM-44 ice machine that was making ice just fine and then suddenly stopped. All seems fine otherwise in the LEDs that show the cycle steps, etc. but when i touch the metalic freezing grid that makes the cubes they are not very cold. It appears as if there needs to have R134a added. How can I check this or should I suspect a bad thermostat?
