Hunting down a mystery leak in an LG steam dryer

Posted by Samurai Appliance Repair Man, in Dryer Repair 04 May 2012 · 1,020 views
LG, dryer, steam, leak

<<<DLEX7177RM Steam dryer has mystery leak that the customer notices after most cycles, coming from near the front center of the machine. I ran this unit for quite some time and could find no leak.>>>


In most cases---this is caused by a partially restricted vent system.

When the back pressure increases due to a restricted/partially blocked vent system---moisture/steam "escapes" from the drum during the cycle (fairly common).

Check all hoses for tight connections as well (it's rare to find a leaky hose).


<<<I could not locate the source of the leak. I went into dx mode and activated the steam generator, and only ended up with a drum full of water>>>


To initiate the DIAGNOSTICS TEST MODE...

Press/hold the MORE TIME and LESS TIME buttons

Then press the POWER button and release all three buttons.

To test the STEAM GENERATOR funtion...

Press the START/PAUSE button 4 times.

NOTE: During the STEAM GENERATOR test mode---the SG pump *will flood* the dryer if allowed to run too long.


<<<Customer indicated that a previous servicer replaced something (maybe steam generator?) and indicated that this part breaks all the time and they should get used to replacing it.>>>




The STEAM GENERATOR in an LG dryer serves 2 functions...

1) Static Reduction---Most of the dry cycles will add a small spray of steam into the drum during *the last* 15 minutes of a cycle.

2)The EASY IRON cycle adds a *heavy* amount of steam to the laundry load to leave clothes very damp in preparation for *ironing*.

If STEAM DRY is selected (any cycle)---the STEAM GENERATOR will be turned off during the last 8 minutes of the cycle.

If using the STEAM FRESH option---the SG will NOT energize if the Moisture Sensor Bars detect moisure in the load (clothing).

Things to check in an LG dryer that's not drying the clothes completely

LG, dryer

<<<I'm working on repairing a LG dryer DLE5977B that is not drying the clothes completely.>>>


Assuming the entire vent system is clean/clear...

If Fabric Softener Sheets are used in the dryer---laundry will be approximately 90% dry (on a regular basis).

This is caused by *wax* build-up on the MOISTURE SENSORS from the FS Sheet.

The waxy residue on the MOISTURE SENSORS will cause the MAIN BOARD to "think" that the laundry has become dry at/near the end of the cycle.

There are 2 options:

1) Discontinue using FS Sheets


2) Clean/scrub the MOISTURE SENSORS with a *ScotchBrite Pad* after each load in the dryer (when a FS Sheet is used)

The MOISTURE SENSORS are located on the *drum side* of the Lint Filter Housing (2 silver metal strips).
These can easily be found on the Lint Filter Housing by placing your head into the drum and looking downward at the Filter Housing.


If a *small* load has been placed in the dryer---the damp/wet laundry may not be making contact with the Moisture Sensors often enough (causing rapid termination of the cycle).
Raising the rear/back leveling legs of the dryer---about an inch higher than the front of the dryer---will cause small loads of laundry to tumble at the front of the drum (continually making contact with the Sensors).

Removing the blower wheel from the motor in a Whirlpool dryer

Posted by Samurai Appliance Repair Man, in Dryer Repair 20 April 2012 · 2,376 views
Whirlpool, Dryer, Blower, Motor
Some tricks, tips, and techniques for removing the blower wheel from the motor in the Whirlpool-built dryer with the lint filter in the top panel.

This is how I'm doing it. TO THE T!

no wonder, you'll never get it apart that way.

Leave the front clip on
use the biggest cresent wrench you can on the blower wheel.make it as tight on the plastic as you can.
rotate the cresent wrench to the right so it's up tight against the cabinet or drum roller shaft
then take a big pair of vise grips and lock it on the belt pulley, lock it in the 12:00 position as tight as possible.
then wrap some electrical tape around the vise grip to keep it from unlocking.
now take something solid an hit the vise grips to drive them clockwise.hit it hard

this works 90% of the time or more.

Lock the belt pulley end shaft in a vise.
Use a pipe wrench to remove the nut on the blower end.
If that fails use a Dremel type cutting wheel to remove the nut.

How to measure dryer vent exhaust temperatures

Posted by Samurai Appliance Repair Man, in Dryer Repair 11 April 2012 · 1,393 views
dryer, vent, exhaust, temperature

What are the Vent temperatures ?

With an empty load, Timed Dry, High Heat, the vent temperature should cycle somewhere between 135F and 160F

Check the Vent air temperature at the back of the Dryer using a probe-type thermometer.

Dryer Vent:
Vent should be rigid metal.
Short lengths of flexible metal may be OK, if not crimped when moving the Dryer into place.
NO plastic
NO screws
Foil Duct Tape is OK.

Check / clean the Dryer Vent

Disconnect the Dryer Vent and check for good air-flow there and where it exits the house.
