Heated air enters the dryer at 140 degrees farenheit,
a portion of the heat energy raises the temperature of the water in the clothes.
When the clothes are cold and wet, the difference is large transfer is rapid
a lot of heat transfers to clothes and the exhaust air is damper and colder
As the clothes get warmer and dryer, proprtionally less heat is extracted from the incoming air, and the exhaust air is warmer and dryer.
When the clothes are dry, and at 140 degrees, the same temperature as the incoming air. no heat is removed from the incoming air
the dryer should then stop heating, draw unheated air through the drum and clothes to cool, and reduce wrinkling
then switch off

the dryer appears to be operating correctly

My LG front loading dryer doesn't dry well


Check the exhaust vent when running and be sure there is a good flow of air. You may have to clean the exhaust pipes all the way through. Dryers require a good flow of air for proper operation.

The valve resistance is 1995 ohms and the ignitor is 185.
*******************************************************************
Inspect the dryer venting from the rear of the dryer to the outside vent hood of the home.
If there's a restriction in the vent--the clothing in the dryer takes longer to dry.
When the dryer is functioning normally---the time required to dry laundry is determined by the *Sensor* located on the drum side of the lint filter housing and by the main control board.
When laundry is near dry--any Time Remaining on the control panel that is *not* needed will be eliminated---except for the last 6 minutes.
The final 6 minutes of any automatic cycle is for cooling down the laundry before the dryer ends the cycle.
If a dryer *counts down* to the last 6 minutes but the laundry is still not dry--the computer will allow the dryer to run until the laundry has dried or defaults (not drying within the additional time allowed).
Dryer vents that are longer than 8 feet with more than (2) 90 degree turns--can affect drying performance.
Setting the DRY LEVEL selector to *Very Dry* will solve most dryability issues. In homes with abnormally long vents--even the longer run time in the *Very Dry* setting is usually not sufficient to dry laundry loads.
Reducing the length of the vent or starting a second cycle becomes necessary to fully dry the clothing.
If a second cycle was started---only the amount of time that is needed to dry laundry will be used before dropping to 6 minutes and then the cycle will end with dry laundry.
*****************************************

LG gas dryers are more sensitive to venting length and air flow resistance. The gas burner can cause a rapid increase in temperature compared to an electric burner.
Rapid temperature rise in a gas dryer leads to premature burner shutdown (longer time required to dry laundry).
The gradual temperature increase of an electric element is more "forgiving" in homes where the dryer venting is less than ideal.
*******************************************

Problem:
The dryer has an auto dry feature which never fully dries the clothes so we wind up manually setting the dry time to an hour
Solution:
LG gas dryers are VERY temperamental in long vent set-ups. If fabric softener sheets are used in the dryer--clean the two stainless steel strips of metal on the lint filter housing with a SCOTCHBRITE PAD--scrub back & forth several times to remove the waxy residue from the fabric softener sheets. Most,if not all manufacturers do *not* recommend using sheets in dryers that have a moisture sensor (electrodes).
However--using a SCOTCHBRITE pad keeps the wax off those sensors which can be seen if looking *into* the dryer drum and at the lint filter housing.
If only *liquid* fabric softener is used in the washer--clean the dryer sensors once a month. Liquid softener also contains wax which can slowly accumulate on the dryer sensors from the laundry washed in the washer.
***************************************************************
Hold down on the 'More Time' and 'Less Time' buttons and press the 'Power' button. if it comes up with tE1 or tE2 you have a thermistor error.

Dryer not getting hot enough to dry clothes or complete cycle


Hi,
If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

if you dryer is gas check out this gas no heat tip....

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...

Clothes do not dry completely on one cycle


Check your dryer vent (the entire length) for lint build-up. Check that the vent is opening properly (the flapper type can come loose and block air-flow).

Those are the most common reasons for an inefficient dryer.

I hope this helps.

sounds like an air flow problem meaning the dryer is not exhausting the hot air. Best way to check is to disconnect exhaust tubing from dryer and run a cycle. If the clothes dry normally the vent to the outside is plugged. Hope this helps

Whirlpool gas dryer is not hot .burner ignights but it is not hot enough


If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.

Normally, this is what happens during an automatic cycle:

  • The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.

  • When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)

  • The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.

This cycle continues until the clothes are dry. But…if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

if this helps please give me a fix ya vote
