Frigidaire Washer Agitates Slowly: Troubleshooting Guide... | appliancefaults.com

Technical Background:

The washer's Motor Control Unit (MCU) controls the motor based on input from sensors and user settings. The agitation and spin cycles utilize different motor speeds and directions, often controlled by separate windings within the motor or different electronic switching within the MCU. A problem affecting the agitation circuit or mechanical components specifically associated with agitation will impact the agitation speed but leave the spin cycle unaffected. Voltage to the motor should be around 120V AC during both cycles.

Symptoms:

The Frigidaire washer agitates slowly, taking an extended amount of time to wash clothes. The spin cycle operates at normal speed and appears unaffected.

Possible Causes:

Worn or broken agitator dogs/cogs
Defective agitator assembly
Weak or failing motor capacitor (if applicable, some models don't have one)
Worn drive belt (belt-driven models only)
Obstruction in the agitator or wash basket area
Partially clogged drain pump (restricting water level)

Solution:

1

Unplug the washer from the outlet.
2

Inspect the agitator dogs/cogs for wear or breakage. Use a flat-head screwdriver to pry them out and replace them if necessary. Part numbers are usually stamped on them.
3

Check the agitator assembly for any damage or obstructions. Replace the entire assembly if needed. Agitators are typically held in place with a 7/16-inch or 1/2-inch bolt.
4

For belt-driven models, examine the drive belt for wear, cracks, or looseness. Replace the belt if needed. Use a 5/16-inch nut driver to loosen any belt tensioners.
5

If your model has a motor capacitor, test it with a multimeter. A capacitor testing tool is best, but a standard multimeter can often give a basic reading to indicate a short or open. Replace the capacitor if it fails the test.
6

Ensure there are no obstructions (clothing, socks, etc.) blocking the agitator or wash basket.
7

Check the drain pump and drain hose for partial clogs that could be restricting the water level. Clear any obstructions.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any repairs. Capacitors can hold a dangerous electrical charge even after the appliance is unplugged; discharge capacitors with a suitable resistor before handling. Always use appropriate safety glasses.

Prevention:

Regularly clean the lint filter and inspect the agitator for wear. Avoid overloading the washer to prevent excessive strain on the motor and agitator components.

Expert Tip:

Many Frigidaire washers have a diagnostic mode that can display error codes and test specific components. Consult the service manual (often available online) to access the diagnostic mode for your specific model.

Frequently Asked Questions

•How do I discharge a capacitor safely?

Use a resistor (around 10,000 ohms, 5 watts) with insulated alligator clip leads to connect across the capacitor terminals for several seconds. Verify with a multimeter that the voltage has dropped to a safe level (under 10 volts).

•Where can I find the service manual for my Frigidaire washer?

Search online using the model number of your washer along with 'service manual'. Websites like AppliancePartsPros and RepairClinic often have them available for download or purchase.

•What is the typical lifespan of agitator dogs/cogs?

Agitator dogs typically last between 3-7 years, depending on usage and the types of clothing being washed. Washing heavy items like blankets frequently can shorten their lifespan.
