Dryers With Moisture Sensors

5 posts in this topic

I've been reading the previous 50 or so posts tonight---and noticed several visitors to the forum had a common "problem" with their dryer---which uses a MOISTURE SENSOR.

The complaint was identical:

"Laundry doesn't always dry" (and the vent system was ruled-out)

The responses were similar:

"Avoid small loads in dryers that have/use MOISTURE SENSORS"


"For small loads---use the TIME DRY cycle"

There is a solution---and it's a very simple one.

Some years back---I had an older lady (widow)---that contacted us regarding her LG dryer.

Her complaint was that the laundry was not dry at the end of the cycle.

Also---the cycle run time/duration was rather short (cycle ended far earlier than initial time displayed).

In her case---she does not wash/dry large loads at all---and rarely does she even have medium sized loads to wash.

On LG dryers---the MOISTURE SENSOR ("bars") are located at the front of the dryer---on the LINT FILTER HOUSING.

If the dryer is dead-level---which hers was---a small load of laundry will tumble in the GIANT DRUM and very erratically come into contact with the MOISTURE SENSOR.

By raising the REAR LEVELING LEGS about an inch---this forced the tumbling small load of laundry to remain at the *front* of the dryer---continually falling/contacting the MOISTURE SENSOR.

On dryers (other brands) in which the sensors are positioned at the rear/back of the drum---simply raise the *front* leveling legs to get the same result.

Technicians can demonstrate to the customer by running the dryer with 2 or 3 small pieces of clothing---laundry will either tumble at the rear of the drum or near the center (in an LG dryer--for example).

Explain to the customer---the MOISTURE SENSORs function and that wet/damp laundry *must* continually come into contact with the sensor (show the customer the location of the sensor).

After adjusting the legs---the customer/owner will notice the laundry moving toward the SENSOR location within 30 seconds of starting the cycle---and remain at that location in the drum for the duration of the cycle.

Dry laundry.

Problem solved :)

I use that tactic myself, and it works well. Now if we can get people to stop running mixed loads of cottons and knits.

That is most excellent advice and very true especially in the older Kenmore and Whirlpool dryers. :rocker:

Another benefit to raising the front or back of the dryer (depending upon where the MOISTURE SENSOR is located)...

Is that if a mixed load of laundry is added to the dryer (denims with t-shirts for example)---the entire load of laundry is more apt to be *dry* when the cycle ends.

In other words---if we have an LG dryer (front mounted sensor) that is DEAD-LEVEL...

Add several pairs of denims to the drum first

Then add a load of t-shirts

When the dryer is started---there's nothing to induce or force the denims (which are heavier fabrics and therefore wetter than t-shirts) to re-position within the tumbling drum from the-rear-to-the-front of the drum during the cycle.

On more than a few occassions---the customer may indicate that:

"If I add a mixed load of laundry to the dryer,the t-shirts will be dry,but the denims will be damp/wet."

With an LG dryer---raising the rear leveling legs causes the DENIMS to tumble towards the front half of the drum (contacting the MOISTURE SENSOR). The T-SHIRTS will be forced under the drum towards the rear half of the drum.

This rotating of clothing (at a slight angle) during tumble---repeats itself over and over.

The end result is that---because the heaver denims (still wet even though the t-shirts were dry) kept falling onto the MOISTURE SENSOR---the MAIN BOARD did not ***reduce*** cycle run-time earlier/sooner.

In this set up (tilting the dryer) mixed laundry loads are more consistently & evenly dried by the time the cycle ends.
