GE Profile UltraFresh Vent vs Samsung Self Clean+: Which... | appliancefaults.com

Technical Background:

The GE UltraFresh system uses a vent and antimicrobial technology to reduce moisture and prevent mold growth. The Samsung Self Clean+ relies on high-temperature water and a specific cleaning cycle controlled by the main control unit (MCU) based on thermistor feedback. Voltage paths involve 120V AC circuits powering the heating elements and pumps, and 5V DC circuits for sensors and logic.

Symptoms:

US homeowners report musty odors from their GE Profile UltraFresh washing machine or that the Samsung Self Clean+ cycle doesn't seem to clean effectively, leaving lingering smells.

Possible Causes:

Clogged vent in GE UltraFresh system
Faulty humidity sensor in GE
Defective thermistor in Samsung Self Clean+
Blocked drain line in either model
Damaged door seal impacting temperature regulation
Malfunctioning control board

Solution:

1

Unplug the appliance from the 120V AC outlet and verify power is off at the breaker panel.
2

For GE UltraFresh vent issues, remove the vent cover (usually with a 1/4-inch nut driver) and inspect for blockages. Clear any lint or debris.
3

Check the drain line for obstructions. A turkey baster or wet/dry vacuum can help clear clogs.
4

Test the thermistor (Samsung) or humidity sensor (GE) with a multimeter. Expected resistance values are typically found in the service manual. Replace if out of spec.
5

Inspect the door seal for damage or gaps. Replace if necessary.
6

If the control board is suspected, visually inspect for burnt components. Replace the control board. Refer to service manual for replacement instructions.
7

After repairs, plug the appliance back in, turn on the breaker, and monitor for proper operation.

Safety Warning:

Always disconnect power at the breaker panel before servicing any appliance. High voltage is present inside these machines. Use proper Lock Out Tag Out (LOTO) procedures to prevent accidental energization.

Prevention:

Regularly clean the lint filter (dryer), use the appropriate amount of HE detergent (washer), and periodically run a washing machine cleaner cycle with bleach or a commercial washing machine cleaner. Ensure the drain line is properly installed and not kinked.

Expert Tip:

Many GE and Samsung washers have a service mode. Consult the service manual (available online with the model number) for the specific key sequence to enter service mode. This allows you to run diagnostic tests on individual components.

Frequently Asked Questions

•What are the typical resistance values for the thermistor in the Samsung Self Clean+?

The resistance value of the thermistor varies with temperature. Consult the Samsung service manual for the specific model. Generally, expect several thousand ohms at room temperature (around 70-75°F). Lower resistance indicates a higher temperature.

•How often should I run a cleaning cycle in my washing machine?

It's recommended to run a cleaning cycle at least once a month, or more frequently if you notice odors or residue buildup. This helps prevent mold and mildew growth.

•Where is the drain line typically located, and what size tubing is it?

The drain line is usually located at the back of the washing machine, near the bottom. It's typically a flexible hose with an inner diameter of 1 to 1.25 inches.
