How do I replace an Electronic Control Board in a Side-By-Side Refrigerator?

In the machine compartment next to the compressor, the drain tube is used to transfer the water from the evaporator to the drain pan, where it can evaporate. If the drain tube is damaged, the water won't drain from the tray and will overflow into the freezer or refrigerator compartment. If the drain tube is damaged you should replace it.

The bi-metal thermostat-trips, also known as the refrigerator defrost sensor, are used to detect when the temperature of the evaporator is getting hot enough to cause overheating. The power was cut off when the sensor tripped. frost builds up on the evaporator fins of the refrigerator and freezer if the defrost sensor trips. To check the sensor for continuity, you can use the volt-ohm meter. If the sensor doesn't show continuity at 0 degrees F, replace it.

The electronic control board controls the compressor and the defrost cycle. When it senses that the compressor needs to run to keep the fridge cool, it sends power to the compressor and fans. The electronic control board receives signals from the temperature sensors in the fridge and freezer. The control board has this information. You can do a diagnostic test on the electronic control board to see how well it works. The most common test is the Forced Defrost test. Instructions on running the diagnostics can be found in the tech sheet. If the control board is malfunctioning, you should replace it.

The fan is on the assembly. The air is moved through the cabinet for cooling. If the fan is malfunctioning, replace it.

The frost from the evaporator is melted by the refrigerator automatic defrost system. The compressor stops, the heating element turns on, and the frost starts to melt. There is a drain pan next to the compressor in the machine compartment where the condensate flows through a drain tube. The water left the drain pan before the next thaw. Diagnostic and repair the problem if the defrost process fails.

The intervals between automatic defrost cycles in the refrigerator is controlled by the defrost timer. The control components in the device are moved by the motor of the defrost timer. When the control contacts in the defrost timer advance into the defrost cycle, the compressor stops and the defrost heater turns on for a period of time to melt frost off of the evaporator fins. This encourages more efficient exchange of heat. When the period of defrost ends, the defrost timer contacts switch back to allow normal cooling in the fridge.

There are ice makers and/or water dispensers in many refrigerators. A water leak can be caused by the broken water line in the refrigerator. Water lines inside the refrigerator are being replaced.

When the door is shut, the gasket on the fridge or freezer door prevents air from entering or escaping the cabinet. When the door is closed, a damaged gasket lets warm, moist air into the fridge. The door seal should be replaced if it's damaged.

Follow these steps to fix your issue:

  1. Disconnect the electrical power

    While the refrigerator is shut off, store any food that could degrade. Shut off the circuit breaker on the refrigerator.

  2. Remove shelf supports from the freezer

    There are shelves and baskets in the freezer compartment. Pull out the supports from the shelf on the right interior wall of the freezer. Refer to your owner's manual if you need to remove baskets and shelves from the freezer.

  3. Remove the back panel

    The back panel of the freezer has mounting screws on it. To release it, pull the bottom of the panel outward.

  4. Unclamp the defrost sensor from the evaporator

    The positioning of the sensor is noted. Release the metal clip that holds the sensor. If you take a digital photo of the defrost sensor, it will help you position the replacement correctly.

  5. Remove the defrost sensor

    Pull the defrost sensor out of the freezer by cutting the wires near it.

  6. Install the new defrost sensor

    Use a wire stripper to get rid of the insulation on the new sensor. The harness above the evaporator has pink and brown wire on it. The wires should be connected using wire nuts. Silicone sealant should be squeezed into the open ends of the wire nuts to keep the connection dry.

  7. Clip the defrost sensor onto the refrigerant line

    The sensor can be clipped onto the line. It should be positioned the same as the original defrost sensor. Push the wires above the evaporator if you don't disturb the sealant on the wire nuts. To keep the wires out of the way, use a cable tie.

  8. Reinstall the back panel

    Put the back panel back in place. The mounting rails can be cracked if the screws are tightened too much. Then snug the screws up with a final twist by rotating them. The baskets and shelves should be reinstalled.

  9. Restore electrical power

    You can restore power by plugging in the refrigerator or the house circuit breaker.

Time required:

45 minutes.

You would need the following tools:

1/4-inch nut driver, work gloves.
