Brand: Whirlpool
Model Number: WRF767SDHZ04
Main Symptom: Display chimes and flashes
What happens & when:

I have a Whirlpool French Fridge that the customer reports is about 16 months old. Model #: WRF767SDHZ04 Serial #: KD0507865. Here is my visit summary from today that includes the report of the customer prior to my visit. I am curious what you think are good next steps if the flashing and chiming returns, but everything else appears to be normal:

During the entire timeline of events there has been no issues with cooling.

The first issue that came up was that there was a non-stop loud humming sound appearing to come from the ice maker in the ceiling of the fridge cabinet that continued for 4-5 hours.

Then later, when ice/water paddle was depressed, there was non-stop chiming and flashing of the blue icons on the display panel and light around the paddle. This was interrupted when the doors would open.

Customer unplugged unit for 10 minutes. Plugged back in and started to flash and chime right away.

Then unplugged overnight. Turned off the ice maker.

At one point, customer did take off the front panel where the display was and undid some connections, but there has been no improvement.

Prior to my visit today, the unit was plugged back in, No flashing or chiming for 15-20 min, then chimed and flashed for 30 min and then stopped. Since then, it has not had any issues for 4-5 hours.

During my visit, I completed multiple diagnostic tests. The ice maker completed a harvest cycle and dropped 6 medium sized cubes and filled with water. A user interface test was done and there are no issues with the display or buttons. Fans and baffle run and no unusual noise. During my visit, the replace water filter light came on, which the customer found curious since it was replaced 6 weeks ago. The customer had a replacement one available and that properly reset the alert. The customer had a non-OEM Whirlpool filter in use and a similar one to replace it.

Even though the User interface tested good in the test mode, this issue sounds likely that there is a problem with the user interface possibly having a short causing the flashing and the chime. Also, check to make sure that the wiring harness in the door does not have a bad connection or damaged wires.

Thanks for the feedback. The UI is definitely a replacement I am considering, but I don’t want to throw parts at the issue without talking it through. I will check wiring harness and wires. I feel like it is particularly interesting that the ice maker noise was involved initially. Odd how an electrical/mechanical issue may have began there and then possibly damaging the UI.

Customer gave me an update that over the last 5 days, no chimes or alerts but water dispenser is running loader than usual. I wonder if there is an issue with the water valve…. The unit is about 16 months old and the house is less than 5 years old i would imagine, so these are some details to consider as well.
