Customer Questions and Answers for Run Capacitor by Whirlpool

Hello Dorothy, To begin with, I don't believe the run capacitor can be the issue because the unit would not achieve 35°F as you stated it does. The compressor would not run long enough to get that cool. First thing to do is clean the condenser coils if there's any lint on them and make sure the unit is pulled away from the wall so the coils are at least 3 inches from the wall. This provides air circulation which is necessary for proper operation of a sealed system. You see, the unit does not make cold, but it removes heat. The heat it removes is carried to the condenser coils where it is dissipated back into the room. The next thing to check is the freezer fan WP2315539. If it's running, note whether the back wall of the freezer has a frost build-up on it. If it does, you have a defrost issue. If this is the case, you probably have a bad defrost thermostat WPW10225581. The defrost timer, which is electronic on this model 4388931, and the defrost heater WP2263749, are the only other two components in the defrost circuit. If there is no frost build-up on the back wall of the freezer, you need to remove the back wall of the freezer to check the frost pattern. If there is only an ice ball on the top left, (where the freon lines come into the freezer compartment), you either have an inefficient compressor, a sealed system restriction, or a freon loss. This means the unit is not financially feasible to repair. (The repair will cost as much if not more than the replacement cost of the unit). If at any point, you have more questions or are not sure of how to interpret the diagnosis, please feel free to re-post and we will assist you further.
