Fix a stacked washer dryer that will not run

We'll check power, door switches on both units, and power-cycle the unit—or tell you when to call a pro for control board or wiring.

Steps

Goal: Confirm the symptom, rule out power, then isolate the fault—door switches or control board.

Check power

Goal: Rule out power loss before opening the unit.

  • Check the circuit breaker for the laundry circuit. Stacked units share one outlet; if the breaker has tripped, both units lose power. Reset the breaker if tripped.
  • Test the outlet with a lamp or phone charger. Check for a tripped GFCI—laundry areas often have GFCI outlets; press the reset button.
  • Unplug the unit and inspect the plug and cord for damage, burn marks, or loose prongs. Plug it back in firmly.
  • Good: Power is on and the plug is secure. Proceed to Power cycle.
  • Bad: Breaker keeps tripping or outlet is dead—fix power first, or call an electrician if the breaker trips immediately.

Power cycle

Goal: Clear a locked control board that can prevent both units from running.

  • Unplug the stacked unit. Wait at least one minute. Plug it back in.
  • Try the power button on both washer and dryer.
  • Good: The unit responds—the control was locked. You are done.
  • Bad: Still no response. Proceed to Check door switches.

Check door switches

Goal: Confirm the washer and dryer door switches engage when closed.

  • Close the washer lid or door firmly. Listen for a click. On top-load washers, the lid switch is under the lid; on front-load washers, the door switch is in the door frame.
  • Close the dryer door firmly. Listen for a click. The door switch must engage.
  • On some stacked units, both washer and dryer doors must be closed for either to run. Test each switch for continuity with a multimeter when closed.
  • Good: Both switches show continuity when closed—the control board may have failed. Call a technician.
  • Bad: One switch shows no continuity when closed—replace it with a matching part. Reassemble and test.

When to get help

Call 911 if you see sparks, smoke, or fire. Call an electrician if the breaker trips when you turn the unit on or you see damaged house wiring.

Call an appliance technician if:

  • Power and both door switches are good but neither unit responds (likely control board failure).
  • You see burn smell or damaged internal wiring.
  • You are not comfortable with electrical checks.

Verification

  • Both washer and dryer respond when you press power or start.
  • No error codes or unusual noises.
  • Door switches (if replaced) show continuity when closed and both units run normally.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify neither washer nor dryer responds; rule out a single-unit problem.
  2. Power Check circuit breaker, outlet, GFCI, and plug connection.
  3. Power cycle Unplug, wait one minute, plug back in; clear a locked control board.
  4. Door switches Check washer lid or door switch and dryer door switch on both units.
  5. Call a pro Breaker trips, power and switches good but no response, or damage—call an appliance technician.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Whether both units or only one fails
  • Circuit breaker and outlet test results
  • Door switch test results (washer and dryer)
  • Steps already tried

Does neither the washer nor the dryer respond?

Press power or start on both units. If no lights, no hum, no movement on either, both are affected.

Press the power button or start a cycle on both the washer and the dryer. Good: neither responds—shared power or control fault. Bad: only one unit fails—see fix-washing-machine-will-not-turn-on or fix-dryer-will-not-start instead.

Yes No (one unit works)

Is power on at the outlet?

Stacked units share one outlet. If power is off, both units fail.

Check the circuit breaker—reset if tripped. Test the outlet with a lamp or phone charger. Check for a tripped GFCI. Good: outlet delivers power. Bad: breaker keeps tripping or outlet is dead—fix power first or call an electrician.

Yes No

You can change your answer later.

Is the plug secure and undamaged?

Loose or damaged plug can prevent both units from receiving power.

Unplug and inspect the plug and cord for damage or loose prongs. Plug back in firmly. Good: secure connection, no damage. Bad: damaged cord—replace or call a technician.

Yes No

You can change your answer later.

Did a power cycle fix it?

Unplug for one minute, plug back in. A locked control board can prevent both units from running.

Unplug the stacked unit. Wait at least one minute. Plug back in. Try power on both washer and dryer. Good: unit responds—control was locked. Bad: still no response—proceed to door switches.

Yes No

You can change your answer later.

Unit is working

The power cycle cleared the locked control. The washer and dryer should respond normally.

Done

Do both door switches have continuity when closed?

Washer lid or door and dryer door must close and engage their switches. On some stacked units, both must be closed.

Close the washer lid or door firmly. Close the dryer door firmly. Test the door switch (or lid switch on top-load washer) on each unit for continuity with a multimeter when closed. No continuity when closed: replace the faulty switch. Both have continuity: control board may have failed—call a technician.

Yes (both good) No (one faulty)

You can change your answer later.

Replace faulty switch and test

Replace the faulty door switch or lid switch with a matching part. Reassemble and test. The unit should respond. If the switch was the only fault, both washer and dryer should run.

Done

Call a technician

Call 911 if you see sparks, smoke, or fire. Call an electrician if the breaker trips when you turn the unit on or you see damaged house wiring. Call an appliance technician if: power and both door switches are good but neither unit responds (likely control board); you see burn smell or damaged wiring; or you are not comfortable with electrical checks.

Done

Frequently asked questions

Why would a stacked washer-dryer not run at all?
Common causes: tripped circuit breaker, dead outlet, loose plug, faulty door switch on the washer or dryer, locked control board, or failed control board. Stacked units share power and often a control board—a single fault can stop both units.
Can I fix a stacked washer-dryer that will not run myself?
Yes. You can check the circuit breaker, outlet, plug, door switches on both units, and power-cycle the unit. Unplug before any repair. Do not open the control board or work on internal wiring if you are not comfortable—call an appliance technician.
When should I call a technician for a stacked washer-dryer that will not run?
Call a technician if the breaker trips when you turn the unit on, power and both door switches are good but neither unit responds, you see damaged wiring or burn smell, or you are not comfortable with electrical checks.
