Kenmore Washer Control Board Replacement Guide

A washer control board is the brain of the machine: it reads the cycle selector, times the fill and spin, talks to the motor controller, and locks the door. When it starts to fail, the symptoms look chaotic precisely because one component is mismanaging every other component. The good news is that a board swap is one of the least physical repairs on a washer — most of the work is diagnosis, not wrenching.

Know Your Builder First#

Kenmore is a store brand, so the control architecture is not universal. Read the first three digits of the model number on the door-frame sticker:

• A 110-prefix machine is built by Whirlpool. These split the electronics into a Central Control Unit and a separate Motor Control Unit — two boards that talk to each other, which is why communication faults are common.
• A 796-prefix machine is built by LG. These use a single main PCB that handles logic and motor drive together.

Ordering the wrong board is the number-one mistake on this repair, and the two families are not interchangeable even when the washer looks identical from the outside.

Symptoms of a Failing Control Board#

• The washer is completely dead — no lights, no response — even though the outlet and breaker are good
• Cycles start and then stall, skip stages, or restart on their own
• The machine fills but never agitates or spins, or spins without draining
• Communication codes such as F70 or F71 appear, meaning the two Whirlpool boards have lost contact
• Codes like F5, F8, or F9 point at the lock, water, or drain circuits the board drives
• Buttons on the console do nothing, or the wrong cycle lights up

Confirm It Before You Swap#

A control board is an expensive part to guess at, so rule out the cheap stuff first. Roughly 40% of "bad board" calls turn out to be a tripped lock switch, a clogged drain, or a loose wire harness. Reseat every connector at the board — vibration works them loose over years. Check the door lock and the drain pump independently, since a stuck lock or a jammed pump will make the board throw a fault that looks like a board failure. Only after the harness, lock, and pump check out should you condemn the board.

The Right Part#

For a 110-prefix Whirlpool-built Kenmore, you may need the Central Control Unit, the Motor Control Unit, or both, depending on whether the fault is logic or drive. For a 796-prefix LG-built machine, it is the single main PCB. Match the OEM number printed on your existing board to the replacement — never rely on the model number alone, because Kenmore ran multiple board revisions within a single model year.

Step-by-Step Replacement#

1. Unplug the washer. This is non-negotiable — the board holds live line voltage.
2. Locate the board. Top-load machines house it under the console; most front-loaders put it behind the top panel, accessed by removing two or three rear screws and sliding the lid back.
3. Photograph every wire connector before touching anything. The plugs are keyed, but a photo removes all doubt on reassembly.
4. Release the connector tabs and unplug each harness. Do not pull on the wires.
5. Unclip the board from its plastic housing and lift it out.
6. Transfer any jumper or the ribbon cable if the new board did not ship with them.
7. Seat the new board, reconnect every harness in the order your photo shows, and confirm each tab clicks home.
8. Refit the panel, plug in, and run a short cycle to verify fill, agitate, drain, and spin.

Tools You Will Need#

• A nut driver or Phillips screwdriver for the console or rear panel
• A phone camera for connector documentation
• A multimeter to verify incoming voltage and rule out the lock and pump

Repair or Replace the Washer#

A control board is one of the pricier parts, so the math matters. If the washer is under roughly eight years old and otherwise sound, a board replacement is worthwhile. If it is over a decade old, or the drum bearings or transmission are also failing, put the board money toward a new machine instead.

What It Costs#

There is no single published price, because a Whirlpool-built board and an LG-built board are different parts, and some 110-prefix repairs need two boards while a 796-prefix needs one. Labor also varies by whether the board sits under the console or behind the cabinet. Price the specific OEM board against your model number and get a labor quote before committing.

How Long It Lasts#

A washer control board should last the life of the machine — well past a decade — because it has no moving parts. When one dies early, the cause is almost always external: a power surge, water intrusion from a leak above it, or heat from a failing motor controller feeding it. Protect a new board with a surge protector and fix any upstream leak before it claims the replacement too.

Reading the Fault Codes#

The board often tells you what it thinks is wrong before it dies. F5 points at the door-lock circuit, F8 at water level or the dispenser, and F9 at a drain problem — each is a circuit the control board drives, so a genuine board failure and a failed component downstream can look alike. F02 flags a slow drain, while F11 is a serial communication fault. Codes like E1 and E2 vary by builder, so cross-reference them against your tech sheet. Use the codes to test the named component first, and treat the board as the cause only after the part it is accusing checks out clean.

Common Mistakes to Avoid#

• Ordering by model number alone. Kenmore ran multiple board revisions per model — match the OEM number printed on your actual board.
• Skipping the harness reseat. A loose connector mimics a dead board and costs nothing to fix.
• Not photographing the plugs. The connectors are keyed, but a photo removes all reassembly doubt.
• Handling the new board without discharging static first. Touch the bare metal chassis before you pick it up.

Before You Open the Console#

If the washer is still covered by a manufacturer or extended warranty, check the terms before opening the cabinet — a self-installed control board can void remaining protection on some Kenmore plans, and a covered board swap is better done as a claim.
