Brand: Whirlpool
Model Number: WRV986FDME01
Main Symptom:Interior refrigerator lights are not working, and the deli/pantry drawer control is completely dark and unresponsive in normal operation, although it passes all service diagnostic tests. The right refrigerator door and pantry/freezer door-switch circuit also behaves abnormally: Service Test 17 stays “closed” even when doors/drawers are opened. The main control board and pantry UI/drawer assembly have already been replaced without resolving the problem.
What happens & when: The interior refrigerator lights stay off at all times, and the deli/pantry control stays dark and unresponsive during normal use.
When the right refrigerator door, either pantry drawer, or the freezer is opened, the refrigerator behaves abnormally: the Replace Filter indicator comes on, and when those doors/drawers are closed it gives a three-chirp alert. The left refrigerator door behaves normally.
In service diagnostics, the pantry control lights, buttons, thermistor, and communication all test normally, but Service Test 17 never recognizes the right-door/pantry/freezer group as open. Water dispensing works normally. When closing those doors/drawers the 3 chirp water filter alarm sounds.
Error Code (if any):
Parts or tests already tried: Replaced the main/HV control board with the W10861900 kit, replaced the complete pantry/deli drawer front and internal harness, and replaced the pantry UI board. None corrected the main symptoms.
Both refrigerator door switches have been continuity-tested. The right RC door and both pantry drawers show the expected resistance change all the way back at the rear control harness (OL closed, about 63 Ω open), yet Service Test 17 stays at 02.
Pantry diagnostics all pass: software communication, all LEDs, Select button, and thermistor. Test 67 behaves abnormally by changing with the right RC door/pantry/freezer group instead of with the water filter.

Hi, based on your testing, this is pointing more toward a wiring/harness issue than the switches themselves. Since the switch resistance changes correctly all the way back at the main board, but Tests 17 and 67 are reacting to the wrong circuits, there may be a damaged return wire, crossed connection, or poor terminal contact.
I would check the bottom-right door hinge harness and connectors first for broken, pinched, or corroded wires. Then unplug the refrigerator and inspect the main board connectors closely for any terminals that have pushed backward inside the plug and aren’t making good contact.
If those connections look good, the next step would be using the wiring diagram and a multimeter to check continuity on the individual wires between the door circuit and main board. That will help pinpoint exactly where the signal is getting crossed or lost.
make sure the refrigerator is unplugged before doing any continuity or resistance testing.
Disconnect the harness at the main board and test each suspected wire end-to-end with your multimeter set to continuity/ohms. A good wire should show continuity and very low resistance. If you get OL/no continuity, that wire is broken somewhere in the harness.
Also check between the suspected wires to make sure they are not shorted together. With the refrigerator unplugged and the connectors disconnected, separate circuits should normally show OL between each other.
Start with the bottom-right hinge harness and main board connector, since that’s where I would look for a broken wire, damaged terminal, or poor connection first.
as it turns out I purchased control board W10861900 and the dispenser panel which is the wrong board for this unit. This board is presenting the same issue the old board did. Is that possible? If so, I need to purchase the proper main control board for this unit? I think that is WPW10675033?
Hi, your refrigerator has three control boards: WPW10675033, WPW10624574, and W10804160, and they all communicate with each other.
I would start with the main control board first. Check all the plugs and wiring and look closely for anything burnt, corroded, loose, or damaged.
If you have a multimeter, check that the main board is getting the correct incoming voltage. If it is, then you can check the voltage going out to the other two boards. That should help narrow down whether the main board is the problem or if one of the other boards is causing the communication issue.
Just be careful if you’re doing any live-voltage testing. If you’re not comfortable working around live power, I wouldn’t risk it.
I would replace whichever board tests bad first and then see how the fridge responds before replacing anything else. It’s possible more than one board is bad, but I wouldn’t replace all three unless the testing points in that direction.
