Whirlpool Refrigerator Flashing 01 – Quick Fix

Take a look at the water dispenser; it has developed a fault if you see this error code. The problem may stem from the water inlet valve that supplies water to the dispenser and ice maker. Inspect the water line connecting the dispenser to the inlet valve and see if it is secure. If everything is in order, test the inlet valve. Replace the valve if it is faulty, but if it is in good working condition, the control board may be malfunctioning and may need a replacement.

Whirlpool Refrigerator Flashing 6 – Quick Fix

If your Whirlpool refrigerator is flashing 6, it may indicate that the thermistor is no longer working. The thermistor is s a sensor in the refrigerator that works together with the thermostat to monitor the air temperature so that it can alert the control board when there is a need to turn on the cooling system. If it becomes faulty, the cooling system may not work as it should and the refrigerator will stop cooling well.

Remove the thermistor and test its resistance using a thermistor. Check the tech sheet that came with the refrigerator to know the correct resistance for the thermistor. If you find that the thermistor has zero resistance or it is at infinity, replace the sensor.

Whirlpool Refrigerator Flashing PO – What It Means

PO on the control panel display of a Whirlpool refrigerator means power outage. The display is usually accompanied by three beeps as the error keeps flashing on the control panel. You will need to confirm you are aware of the power outage to stop the beep and the PO should disappear from the display. However, the beep may stop only temporarily if the internal temperature is high, and it will stop only when the temperature drops.

Press Measured Fill on the control panel to confirm the outage and when it is confirmed, the error code should disappear from the display. But you must wait for the temperature to drop before the beeping stops.

Whirlpool Refrigerator Flashing Red Light in the Freezer – What to Do

The red light flashing in the freezer may come from the ice maker. There is a red status light that should be steady on the ice maker; it is for running diagnostics. Monitor the light; if it is steady for five seconds or more, the optics board on the ice maker is in good working condition.

But if the red light flashes twice, stops, and flashes again, the optics board is either defective or obstructed. Clean the receiver and try again to see if the diagnostics light steadies. If it continues flashing, the board may need a replacement.

Whirlpool Refrigerator Flashing PEO 000 – What to Do

The refrigerator needs to be programmed if you find this code flashing on the display. Contact the Whirlpool Service Center to report the programming issue and request service. You will need to program the refrigerator if you replace the control board. Some Whirlpool refrigerator models can be programmed following these steps:

Locate the door alarm button and press it. Hold it and press the freezer temperature down button at the same time. Hold it for about three seconds and release the door alarm button. The display should show PE to indicate the unit is in programming mode. Next, confirm the entry by pressing the temperature down button for the freezer one more time.

When you do this, the display should show the current refrigerator program code. Check the refrigerator’s serial plate to find the program code and see if it is the same as what is on the display. If the codes are the same, exit the programming mode by pressing the door alarm button and holding it for about three seconds.

But if the codes are not the same, press the refrigerator up or down button to adjust the value. The decimal point on the display shows you the selected digit and pressing the freezer temperature up selects the next number. When you get the correct program code, press the freezer temperature down button and hold it until the code flashes on the display. It indicates the code is saved, so you can press any button to exit the programming mode.

Note: The refrigerator does not save the wrong program code. So if you enter the wrong value, the unit will beep and you have to start the process from the beginning. 0000 does not work for the refrigerator. Also, this process only works for specific models, so contact the Whirlpool Center for instructions in programming the control board if there are no clear instructions.

Whirlpool Refrigerator Lights Are Flashing – What to Check

A few faults in the refrigerator can cause the lights in the refrigerator to flash. Check the dimmer, controller, and module to determine the faulty one, as this article explains. The problem may also stem from a faulty control board, but do not be quick to replace the board until you are sure it is malfunctioning. You can also consider replacing the lights to see if it fixes the problem.

Whirlpool Refrigerator Blinking Green Light – Quick Fix

The freezer temperature may be too high if the green light in your Whirlpool refrigerator is blinking. Check the temperature setting for the unit and if it is too high, adjust it until you achieve the correct setting. Follow the instructions in the user manual to adjust the temperature, ensuring to keep it at 37 degrees Fahrenheit for the refrigerator and 0 degrees Fahrenheit for the freezer.

If the temperature setting does not fix the problem, check the door seal. Ensure it is still working; it may be loose, dirty, or weak. If loose, tighten it by pushing the loose areas back into place. Clea the seal if it is dirty, using a cloth or old toothbrush to clean all stains. But if it is weak, replace it. Otherwise, the refrigerator door cannot close and the temperature will always rise.

You may also want to check the items in the freezer to ensure none is sticking out and keeping the door from closing tightly. Rearrange items in it if necessary and keep the door shut for as long as possible. It may help lower the temperature and stop the green light from flashing.

Whirlpool Refrigerator Control Panel Flashing – How to Fix

If the control panel on your Whirlpool refrigerator is flashing, it may be because the wires are loose. The wire connectors are usually under the cover of the hinge, so inspect them by removing the cover. But before checking the connectors, try resetting the control panel. Disconnect the refrigerator from electric power for some hours and reconnect it. This reset may fix the problem.

However, if the control panel keeps flashing, do the following:

Remove the cover over the hinge and inspect the wiring that goes to the control panel. There may be screws holding the cover in place or you may just pry it off. Check to see if the wire connectors are loose and if they are, fix them. But if there are damaged wires, you may need to replace them and that may require the services of a professional.

Ensure you push the wires and harnesses back in their proper positions after reconnecting loose ones or replacing damaged ones as they apply. A poor arrangement may keep the control panel flashing or worse still, cause more issues with the refrigerator. If these are not the issue or do not fix the problem, consider resetting the control panel.

Disconnect the refrigerator from electric power for a few hours, two to three hours or more, and reconnect it. During this time, leave the refrigerator untouched so that it can properly reset. Also, consider storing perishable food items in another refrigerator or an ice-packed cooler to preserve them.

However, get professional assistance if the problem persists. The refrigerator may require urgent servicing, so contact Whirlpool or use an independent appliance technician for the job.

Whirlpool Refrigerator Flashing 3 – Quick Fix

If you find 3 or 03 flashing on the display of a Whirlpool refrigerator, check the condenser fan or the evaporator fan. Specifically, check the motor connections to ensure everything is in good working condition as this article on Whirlpool refrigerator error explains.

Whirlpool Refrigerator Door Alarm Light Blinking – Solved

Possible causes for the door alarm light blinking on a Whirlpool refrigerator are leaving the door open for too long and poor leveling. It is possible that you left the refrigerator door open for longer than five minutes. The door ajar light starts blinking with an accompanying beep and you need to close the door tightly and not open it for a few hours.

Check the door seal to ensure it is in good working condition. Also, ensure nothing is sticking out of the refrigerator, such as a shelf or bin so that the door can properly close. If the door does not touch the door switch, the control board reads it as the door being open and triggers the alarm light to blink.

Furthermore, check the refrigerator’s leveling. It must be leveled from the front to the back, with the front being a little higher than the back. This enables the door to close automatically and tightly seal. Also, the refrigerator must be balanced on all sides. Follow the instructions in the user manual to level the unit or use this guide for leveling steps.

Finally, the control board may be faulty. This is especially true if the interior refrigerator lights are not working along with the blinking alarm light. Get a replacement control board after testing the old one to be sure it is damaged. Contact Whirlpool to get the right part or order using the model number of the refrigerator.

Whirlpool Refrigerator Water Filter Light Blinking – Quick Fix

Several factors cause the water filter light on a Whirlpool refrigerator to blink. First, check to see if the filter needs a replacement. If the filter is older than six months in use, the filter light is alerting you to the need for a replacement. Ensure you get the correct type of filter for your Whirlpool refrigerator model and follow the instructions to replace it.

But if a filter change is not the problem, and you are sure you are using the correct filter type, remove the filter and inspect it for any damage. Check the head for dirt or debris and see if there is any crack on it. If it is dirty, wash and remove the dirt. And if it is damaged, replace it. When putting it back into the refrigerator, ensure you install it correctly. Incorrect installation may keep the light blinking or cause issues with the ice and water production.


If you have a problem with a Whirlpool refrigerator flashing, it is crucial to find an immediate solution. A refrigerator light should not flash or blink unless you replace the main control board and need to reprogram the unit. And after that, the light on the control panel should stop blinking.

Errors codes may also cause lights to flash, so follow the user manual to determine what the codes mean and fix them. If the interior lights are flashing, replace the bulb or light assembly. The light socket may also be faulty, causing the flashing light, or the light module needs a replacement. If you have issues fixing your Whirlpool refrigerator with flashing lights, contact Whirlpool or hire an independent technician for further assistance.
