Kenmore Washer Control Board Replacement Guide — Cost, Signs & DIY Tips
Kenmore washers use one or two control boards depending on the OEM platform. Whirlpool-built models (110-prefix) have a Central Control Unit (CCU) that manages the wash cycle logic and may have a separate Motor Control Unit (MCU) on newer models. LG-built Kenmore Elite front-load washers (796-prefix) use a single main PCB that handles both cycle logic and motor control through an inverter-direct-drive system. The first three digits of your model number determine which boards your machine uses and where to find the correct OEM replacement part.
Decode Your Model Number
- 110 — Whirlpool: CCU behind the console panel. MCU (if equipped) behind the rear panel or underneath. Older 110-prefix top-loaders with mechanical timers have no control board.
- 796 — LG (Kenmore Elite front-load): Main PCB typically behind the rear panel or under the top panel.

Signs Your Control Board Needs Replacement
Whirlpool-based (110-prefix):
- Error codes F02, F11, F70, or F71 on the display
- Washer does not respond to any button presses despite having power
- Cycle starts but stops mid-cycle with no error code
- Individual buttons or cycle selections stop working
LG-based (796-prefix Kenmore Elite):
- PE, LE, or dE error codes that persist after testing related components
- Touchscreen dead zones or partial response
- Motor does not engage even though the board powers on
Control Board Cost Breakdown
| Factor | Range |
|---|---|
| OEM Whirlpool CCU | $80–$200 |
| OEM LG main PCB | $100–$280 |
| Aftermarket | $50–$150 |
| Cross-reference savings | 30–40% |
| Professional labor | $100–$200 |
| Total (DIY) | $60–$280 |
| Total (professional) | $160–$550 |
Search for the Whirlpool or LG OEM part number directly — the identical board under the Kenmore label costs 30–40% more.

How to Replace
Whirlpool-based (110-prefix) — CCU behind console:
- Unplug the washer
- Remove the console panel (screws at rear or under end caps)
- The CCU is mounted inside the console with multiple wire harness connections
- Photograph all connections before disconnecting
- Remove mounting screws/clips, swap boards, reconnect
- Reassemble. Time: 30–45 minutes.
LG-based (796-prefix):
- Unplug the washer
- Remove the top panel (screws at rear) or rear panel depending on model
- The main PCB is in a protective housing. Disconnect wire harnesses (multiple keyed connectors).
- Remove mounting screws, swap, reconnect
- Time: 45–60 minutes.
Tools: Phillips #2, 1/4-inch nut driver, smartphone for connection photos.
When to DIY vs. Call a Professional
- Whirlpool CCU (110): Moderate, 30–45 minutes. Multiple connectors but all keyed.
- LG main PCB (796): Moderate-difficult, 45–60 minutes. More connectors and ribbon cables.
- Call a professional if: Uncertain which board failed, or if the washer has multiple error codes suggesting broader electrical issues.
The Real Cost of DIY
Average DIY attempt: $150-400 in tools you may use once, plus the risk of further damage. Our diagnostic visit costs $0 — we find the problem and give you an honest quote.

Lifespan
- Whirlpool CCU: 8–15 years
- LG main PCB: 6–12 years
- Power surges are the #1 killer — use a surge protector
The Kenmore Washer Model Number Decode Strategy
Every Kenmore washer repair begins with the model number prefix — it reveals the OEM manufacturer and determines the entire repair approach:
- 110 — Whirlpool (most common, top-load and some front-load models)
- 796 — LG (Kenmore Elite front-load washers with inverter direct-drive motor)
- 417 — Frigidaire/Electrolux (less common)
Whirlpool 110-prefix models span decades of production and include multiple platforms:
- Older direct-drive top-loaders: Motor connects to transmission via a motor coupling. The coupling ($10 rubber/plastic part) fails far more often than the motor itself — always check the coupling first.
- Newer VMW (Vertical Modular Washer) top-loaders: More electronic, separate drain pump, different access patterns.
- Some front-load models are also 110-prefix.
LG 796-prefix Kenmore Elite front-loaders use an inverter direct-drive motor mounted directly on the rear of the tub — no belt, no transmission. This design is efficient but repairs require different procedures than the belt-driven Whirlpool platform.
The cross-reference savings strategy applies: order the Whirlpool or LG OEM part number directly rather than the Kenmore-branded equivalent for 30–40% savings on the identical part.

Common Kenmore Washer Error Codes by Platform
Whirlpool-based (110-prefix): F5 E1/E2 (lid lock), F8 E1 (water level), F9 E1 (drain), F02 (drain timeout)
LG-based (796-prefix): OE (drain), PE (pressure sensor), LE (motor), dE (door lock), UE (unbalanced load)
Knowing your platform's error codes helps diagnose the failing component before ordering parts.

Decode Your Kenmore Washer Model Number
Every Kenmore washer repair starts with the model number prefix:
- 110 — Whirlpool (most common, top-load and some front-load). Includes older direct-drive and newer VMW (Vertical Modular Washer) platforms.
- 796 — LG (Kenmore Elite front-load). Inverter direct-drive motor, no belt or transmission.
- 417 — Frigidaire/Electrolux (some front-load models).
Critical platform differences:
- Whirlpool 110-prefix direct-drive top-loaders use a motor coupling (-5) between the motor and transmission — this coupling fails far more often than the motor itself and is the first thing to check when the drum won't turn.
- Whirlpool 110-prefix VMW top-loaders have electronic controls, a separate drain pump, and a suspension system with rods rather than springs.
- LG 796-prefix Kenmore Elite front-loaders use an inverter direct-drive motor mounted on the tub — no belt, no transmission. Repairs require different procedures than Whirlpool platform.
The cross-reference savings strategy: order the Whirlpool or LG OEM part number directly rather than the Kenmore-branded equivalent for 30-40% savings.
Is It Worth Your Time?

Platform-Specific Control Boards
Whirlpool 110-prefix direct-drive: Older models use a mechanical timer — no electronic board at all. If your 110-prefix washer has a rotary dial for cycle selection, it likely uses a timer rather than a control board. Timer failures cause the cycle to get stuck at one phase.
Whirlpool 110-prefix VMW: Modern VMW top-loaders have two boards: the CCU (Central Control Unit) behind the console and the MCU (Motor Control Unit) near the motor at the bottom. The CCU manages cycle logic; the MCU manages motor speed and direction.
LG 796-prefix Kenmore Elite: LG front-loaders have a main PCB (behind the top panel) and a display board (behind the door). LG boards use different diagnostics than Whirlpool — access diagnostic mode by pressing specific button combinations (typically Spin Speed + Soil Level simultaneously for 3 seconds).
CCU vs. MCU Diagnosis (Whirlpool VMW Models)
If the washer fills and drains but the drum doesn't move: suspect the MCU (motor control) or the motor itself. If nothing works at all (no fill, no drain, no display): suspect the CCU (main control). If buttons don't respond or the display is garbled: suspect the CCU or the user interface board.
The MCU is near the motor at the bottom of the washer. The CCU is behind the console panel at the top. Each has 3-6 wire harness connectors. Photograph everything before disconnecting.
The Risk of Getting It Wrong
A wrong diagnosis often turns a simple fix into a costly replacement. Without proper diagnostic tools, you might replace the wrong part — or cause additional damage. Our free diagnostic eliminates the guesswork.

Timer Replacement (Older Models)
On older 110-prefix Kenmore washers with a rotary dial timer, the timer is a mechanical device with a small motor that advances a cam through switch contacts. When the timer fails, the washer gets stuck at one cycle phase or skips phases. Timer replacement: remove the console back panel, pull the dial knob, remove the timer mounting screws, disconnect the wire harness, and swap. Cost: $50-$120 for the timer.
FAQ
How much does a Kenmore Washer Control Board cost?
DIY: $60–$280. Professional: $160–$550. Cross-reference the OEM part number for 30–40% savings.
How do I reset my Kenmore washer control board?
Unplug for 1 minute, then replug. For Whirlpool-based: also try the Recalibration mode (specific button sequence varies by model). If symptoms persist after reset, the board has a hardware failure.
Can a bad control board cause my washer to leak?
Indirectly — if the board fails to close the water inlet valve properly, overfilling and overflow can occur. But most leaks are mechanical (hoses, pump, tub seal), not board-related.
Is it worth replacing the board on an old Kenmore washer?
Under 10 years: yes. Over 10 years with board as only issue: compare repair cost to new washer ($500–$1000).
