Kenmore Dishwasher Fan Replacement Guide

Kenmore dishwashers come from several factories, and the drying hardware varies by builder. Wet dishes do not always mean a dead fan.

Does Yours Have a Fan?#

Read the model prefix off the rating plate on the door or tub wall:

• 665 (Whirlpool) — mostly a passive vent plus a heated-dry element; no fan motor, though some higher-end units add a vent fan.
• 722 (LG, Kenmore Elite) — an active drying fan, usually at the rear wall or in the door assembly.
• 630 (Samsung) — fan-assisted drying on most models.
• 587 (Frigidaire) — a mix of passive vent and fan-assist by model year.

Buying the fan or vent part under the true builder's OEM number instead of the Kenmore label typically saves 30–40%.

Real Fan Failure vs. Look-Alikes#

On fan-equipped models (722 Elite, some 665):

• Dishes come out dripping even on heated dry
• No low airflow hum during the dry phase
• The dry cycle runs full length but plastics stay soaked
• The fan rattles or grinds — a bearing going

Symptoms that only look like fan failure:

• Droplets on plastic — plastic does not hold heat like glass, so some moisture is normal
• Uneven drying — usually a loading pattern blocking the vent path
• White film or spots — that is water hardness, not drying

Drying Problems Without a Fan#

Many Kenmore dishwashers have no dedicated fan and dry by condensation or heat alone. If yours is a 665 with wet dishes, check these before hunting a fan:

1. Empty rinse-aid dispenser — the number-one cause; rinse aid sheets water off dishes instead of leaving droplets.
2. Incoming water too cool — it should reach at least 120°F; run the nearest hot tap before starting.
3. Plastics on the bottom rack — plastic holds water and does not benefit from condensation drying, so move it up top.
4. A failed heating element — it heats the final rinse, and without it drying collapses.

Replacing the Fan or Vent#

LG Elite (722) drying fan:

1. Cut power at the breaker.
2. Pull the dishwasher out (disconnect water supply and drain hose).
3. Remove the rear access panel — six to eight Phillips screws.
4. Find the fan motor high in the rear of the tub.
5. Unplug the 2-pin connector and back out the two or three housing screws.
6. Fit the new fan the same way, reconnect, reassemble, and run a heated dry to confirm airflow.

Whirlpool (665) vent assembly:

1. Cut power.
2. Open the door and find the vent at the top of the inner door or front-top of the tub.
3. Remove the inner-door-panel screws (Torx T20).
4. If a wax-motor actuator drives the vent and it has failed, that is a separate part.
5. Disconnect the actuator wiring, release the clips or screws, and fit the new assembly.

Tools: a #2 Phillips, a Torx T20 for Whirlpool models, a 1/4-inch nut driver, a flashlight, and pliers.

The Tissue Test and Lifespan#

To check a vent fan, hold a thin tissue near the vent opening during Heated Dry — it should flutter if the fan runs. No movement means a dead motor or a stuck louver. LG fan motors typically last 8 to 12 years; on Whirlpool vent assemblies the wax-motor actuator is the weak link, at 6 to 10 years.

The Cheapest Fix Is Often Free#

Before spending on any drying part, top up the rinse-aid dispenser and run a normal load — on condensation-dry models this single step resolves the large majority of wet-dish complaints on its own. Load plastics on the top rack where they drain better, run the hot tap at the sink before starting so the final rinse water is genuinely hot, and give the door a crack at the end of the cycle to vent trapped steam. If dishes still come out soaked after all of that on a fan-equipped model, then the fan motor or a stuck vent louver has finally earned the closer look and the replacement.
