Are you sure the switch on the door is working properly has this been checked properly if so the probelm could be with the motor as the build up of lint could cause it to over heat therefore blowing something on the board this will need to be checked you will need to check that you have got power going to the motor and the correct amount of power myself i would have said replace the switch on the door but if you are sure you have checked this then the problem could be the motor or the board that powers the motor check all conectionsand look to see if you can see any areas that look like it has over heated if you have a resistance testor you could check the board if not you will need to go to a repair shop and get them to test the board and motor for you hope this is some help

Did you clean out the lint filter at the front, heat is the enemy. Clean out all lint from front, if you are handy, get around back and remove all lint and dust by blowing compressed air.

A leading cause of poor drying results in that type of dryer is lint build up in the blower/lint filter housing. That build up will restrict air flow through the dryer causing very long dry times. To repair that the front panel would need to be removed and clean all the lint build up from that housing and blower wheel area.

To remove the front panel DISCONNECT POWER TO THE DRYER, on the bottom of the dryer inside of the door rim will be 2 phillips headed screws,remove those and lift off the top. At the top corners where the front panel connects to the cabinet will be 2 more phillips headed screws remove those and the front panel will pull off and out of the way. With the front panel off the blower housing will be in the lower left side clean lint from it and also the sure to clean all the lint from the lint filter housing which will be attached to the back side of the front panel. In addation to cleaning that area be sure to check and clean the exhaust duct tube as well.

I have a lg tromm dle2514 dryer and the check filter light is on. I am willing to clean it (I've already cleaned the front filter area) I just have no idea where there is another filter

There is no other filter to clean other then the one lint filter.
I would check the dryer vent to make sure it's not restricted with lint build up or has any kinks in it. Also check the outside flapper at the end of the dryer vent to make sure it's clear of lint and able to open all the way.
If your dryer vent is ok and the lint screen is clean then I would remove the front of the dryer and check the blower/fan housing for lint build up.

Clothes dryer velocity has slowed down to point that clothes do not dry. Thank you very much. Paul J.

Hi Paul and welcome to FixYa. I am Kelly. When you say velocity I am assuming we are talking about airflow and not the tumble speed. There are 2 things that cause poor air flow.
1. Lots of lint build up either inside the dryer or in the output vent ducting expecially at the outside thru the wall vent flapper.
2. The blower wheel on the drive motor has a damaged center hub and is spinning on the motor shaft vs driving at full speed.

Pull out the lint filter use a flashlight and look in the very bottom area of the lint filter air passage. This area is notorious for lint accumulation. If you note lint use a vacuum crevice tool and a wire coat hanger folded into a U shape to reach deep into the passages so that you can use the crevice tool to remove the lint.

The lint filter itself can cause restricted airflow. If you use dryer sheets (Fabric softener) these over time accumulate a mirco particulate on them that when you wipe off the lint it appears clean but the air passages are clogged with the dryer sheet material. Wash the lint filter with vinegar and water using a brush, then soap and water.

Next go outside and check the thru the wall exhaust of the dryer vent. Reach up inside the flapper and check both sides of the flapper for lint build up. Clean as needed.

Disconnect the vent ducting at the back of the dryer. Start the dryer. The airflow commig out the back should gently push a relaxed hand away from the exhaust hole. If the air flow is weak use a flash light and look deep into the vent ducting inside the dryer checking for lint build up. Clean thoroughly.

If after doing all of the above you still have weak airflow then the blower wheel area is suspect in the form of either a damaged blower wheel or lint build up at the blower housing exit.

Give it a good cleaning and see what happens. If you sitll have air flow problems there is more I can do to help you with pictures and how to dis-assemble the dryer. Just repsond here and I will gladly help you.

Thanks for choosing FixYa.

Dryer turns on, drum turns, all appears to work fine, but we get no heat. Pulled front panel and noted the heating element/ignitor does not ignite. Amy experience with this? Bad ignitor? bad gas valve?...

You may have a bad spark ignitor.. Check the vent tubing for any blockage of clogged lint build upfirst.The moister sensor detects that and will keepthe heat off until the the lint clogs are cleared

Ge DRYER dpgt750EC2PL back wall of drum gets very hot. Occassional smell as if something starting to burn. How do I open the top lid to get inside to find out problem

This may sound a bit over simplified but when a dryer starts to get hot inside it is a sign of an airflow problem.

Start with the outside vent flapper. Check to see if there is lint build up on the flapper / louvers.

Pull off the vent hose and check for lint build up. If the vent hose is a flexible plastic hose they have a tendancy to clog with lint in the sprials and then the lint contines to build up until airflow is restricted.

After checking external vents and ducts next remove the lint filter. If you use dryer sheets wash the filter with white vinegar to remove the build up. It may appear clean but the material from the dryer sheets clogs the filters.

In the area around the lint filter check the ducting / air passages for lint build up and clean it.

In the process of all the cleaning do NOT use anything sharp. A vacuum crevice tool and a Looped metal coat hanger do wonders for cleaning assistance.

Before you reconnect the dryer vent try running the dryer with a light load of anything wet to see if it drys properly with the vent disconnected. After that reconnect the vent and repeat the same drying test to see if the drying times are close to the same.

This should solve your hot dryer problem.. If it does not then respond here and we can talk about taking your dryer apart.

Thanks for using FixYa.


the air flow out of the dryer it should be a very high volume.

The check filter light is just a reminder light and cannot be reset.  Nothing to worry about.  Just keep the filter clean before each use.

Bosch Dryer lint filer warning

The Bosch Dryer has a temperature probe in the heater exit and in the exhaust area visible when you open the door. If the temperature difference between the two gets to high, the lint filter is assumed to be plugged and the alarm goes off.

It seems that the temperature probe at the heater, can end up with a faulty connection to the control panel over time due to corroded contacts or lint build up. When this happens the control panel thinks the filter is clogged and it may also not turn on the heating elements properly. Remove the back cover over the heating element (12 screws) and then remove the one screw holding the red wiring connection to the dryer body. You can then wiggle out the wiring connection and clean / unplug and replug in the connector for the sensor. (plug with two small wires only). A little hard feeding the connector back through the hole so take your time and don't damage the wires). Should all work again. May want to inspect inside the heater at same time and make sure the overheating switch is not tripped. ( press in the red button).
