How to Unclog the Defrost Drain in a KitchenAid Refrigerator

To unclog the defrost drain in a KitchenAid refrigerator, mix a little warm water with vinegar and pour it down the drain hole. This removes ice or debris from the drain hole. Pour the water until it is clear and runs free.

Alternatively, you can use a turkey baster or a syringe to squirt the water down the drain hole. Also, in place of water, you can use a stiff stick or a screwdriver to clear the drain. But you need to do this carefully and gently.

How to Force Defrost a KitchenAid Refrigerator

To force defrost a KitchenAid refrigerator, do the following:

1. Open the door of the refrigerator and press the button for the door alarm and hold it.

2. Now, press the button that reduces the temperature for the refrigerator section (refrigerator down button) and hold the button.

3. Release the button for the door alarm and after about 3 seconds, the code Fd will appear on the display on the left.

4. Press the button that reduces the refrigerator temperature (refrigerator down button) a second time. SH will appear on the display on the right.

5. For the third time, press the button that reduces the refrigerator temperature. Fd and SH will start blinking on the display, showing that the refrigerator has gone into the defrost mode.

How to Manually Defrost a KitchenAid Refrigerator

To manually defrost a KitchenAid refrigerator, take the following steps:

1. Turn the Refrigerator Off

Unplug the refrigerator from the wall outlet to turn it off. If you cannot reach the wall outlet, shut down the circuit breaker for that part of the house.

2. Empty the Freezer

Remove every item in the freezer and store them in another freezer or in a cooler. This is to preserve the perishables and retain some of the coldness.

3. Leave the Door Open

For the duration of the defrost process, it is necessary to leave the door of the freezer open. This speeds up the defrost process. Putting a bowl of hot water in the freezer also helps to speed up the defrost cycle. Give it time to work, at least 8 hours. If the ice buildup is high, you may have to leave it for about 24 hours.

4. Mop Up Water

Place towels around the edge of the refrigerator to absorb dripping water. If you can, also place a pan at the base to catch any excess water.

When all the ice melts, take a dry towel and clean the inside of the freezer until it is completely dry.

5. Turn the Refrigerator On

Plug the refrigerator back in or turn on the circuit breaker to power the unit. Give it time to resume normal operations, at least 24 hours. After this time, put food items back inside it.

How to Replace the Defrost Heater in a KitchenAid Refrigerator

To replace the defrost heater in a KitchenAid refrigerator, here are the steps to follow:

1. Turn the Refrigerator Off

Unplug the refrigerator from the wall socket or turn off the circuit breaker. This is the first step for fixing any electrical appliance.

2. Empty the Freezer

Open the door of the freezer. Remove the food baskets first. Then, detach the shelves from the spacers and holes and take them out.

3. Expose the Evaporator Coils

Unscrew the four screws holding the top panel at the back of the freezer in place and remove the panel. Then, remove the bottom panel by rotating it and pulling it out. Once they are out of the way, you will see the evaporator coils. The defrost heater is found at the bottom of the coils with its wires wrapped around their right side.

4. Disconnect the Wires

Disconnect the wire harness that holds the heater to the thermostat and the wall of the freezer and unthread the wire of the heater from around the right side of the coils. With a needle-nose pair of pliers, detach the aluminium clip that holds the heater secure to the bottom of the coils and pull the heater out.

5. Install the New Heater

Put the new heater in the place of the old one. Replace the clip with the pliers and thread the heater up the right side of the coils. Clip the thermostat to the copper tubing at the top and reconnect the wire harness attached to the heater.

6. Put the Freezer Back Together

Mount the bottom back panel back in place and secure the top panel with the four screws using a ¼ nut driver. Slide the shelves back in and replace the food baskets.

7. Turn the Refrigerator On

Plug the refrigerator back in or turn on the circuit breaker to power the refrigerator.

KitchenAid Refrigerator Defrost Water Leak – How to Fix

If your KitchenAid refrigerator is leaking water during the defrost cycle, check the following:

1. Defrost Drain

If the defrost drain is frozen or clogged with dirt, it will stop water from melted ice from leaving. Instead, the water will back up into the pan and overflow, leaking out from under the refrigerator.

Therefore, check the defrost drain and clean it if it is clogged or frozen. With warm water in a syringe or turkey baster, squirt it into the drain to defrost the ice. You can also mix some warm water with vinegar and pour it down the drain to clear dirt or ice.

Alternatively, clean the drain with a stiff wire or a screwdriver to clear it of debris. Then, pour warm water down the drain to further clean it. Keep pouring the water until it is clean and runs without restriction.

2. Drain Pan

Inspect the drain pan to see if there are cracks in it. Also, check to see if it is frozen. This will explain why there is a water leak.

If the pan has any crack on it, then it can no longer hold water and needs to be replaced. But if it is frozen, pour hot water into it to defrost the ice and check the defrost drain line to be sure nothing is causing water to back up into the pan and freeze there.

KitchenAid Refrigerator Stuck in Defrost Mode – What to Do

If a KitchenAid refrigerator is stuck in defrost mode, check the defrost timer. It is the most probable reason for this problem. If it is broken, then it could be stuck in the defrost cycle and not advance into the cooling cycle so the unit can cool.

Locate the defrost timer for the KitchenAid refrigerator model you have. Using a flathead screwdriver, rotate it counterclockwise until it clicks. If it clicks, then it is defective and needs to be replaced. This is because it should advance automatically; it should not have to be moved manually before it advances.

KitchenAid Refrigerator Will Not Defrost – Solution

One or more of the components of the defrost system is defective if a KitchenAid refrigerator will not defrost.

Check the defrost heater. With a multimeter, test the heater to check for continuity. If there is no continuity, replace the defrost heater.

But if the heater is working fine, then check the defrost timer. Turn it counterclockwise with a screwdriver until you hear a click. If you hear the click, then the timer needs to be replaced because it is defective. Normally, it should advance into the defrost cycle automatically if it is working fine.

However, if the heater and the timer are not defective, it is time to check the defrost thermostat or the defrost control board. You will find the thermostat at the top of the evaporator coils, right where the defrost heater is connected with a wire harness. And you will find the defrost control board in the control console inside the refrigerator.

Quick Note

It is important to consult the owner’s manual of your KitchenAid refrigerator if you find it difficult to defrost the unit. You can also contact any of our experienced refrigerator technicians or call KitchenAid service center to direct on what to do.

Stop! Before repairing your appliance, unplug it from the wall socket. If the wall socket is out of reach, turn off the circuit breaker for that part of the house. Doing this protects you from electrocution.

Additionally, wear work gloves if you have any, to protect your hands while working on any electrical appliance, especially if the appliance is a refrigerator or a freezer.
