Dryer not heating
I followed video instruction in disassembling and set screws from each section into diferent small bowls in the order they were removed. Hardest part was some of the screws were really hard to get loose without stripping them and my control panel did not match video but I figured it out. Replacing the parts were easy and putting it back together. While it was apart I cleaned everything including fan blower wheel. Thanks for the right parts and your online video. With your help and a prayer this 62 year old woman fixed the problem and dryer runs like new.

dry wasn't drying due to no heat.
I'm not for reading instructions. So I just dove right in and took the dryer apart to get down to the motor. I gave the dryer a thorough cleaning and replaced the 3 parts I ordered from the online recommendation. Wish I would have ordered 2 sensors and the 2 thermostats that are near the burner. Just so replace beings I was in there. Replacing the parts was easy, found them just by looking for matches to the new parts. Reassembled the dryer, dont think I put a single screw back where I got it lol. And still haven't put the top lid back on due to difficulty. Not sure if I even needed any parts, found a nest in my outside vent completely plugging it. But after a good cleaning and replacing the parts the dryer dries the best it has since we've owned it. The dryer came with our house which we bought 3 years ago and it was 2 years old when we purchased the house, so it is now 5 years old.

Replace 4 roller bearings.
Following the reference video, step by step and taking progress photos along the way, organizing screws and hardware as they were removed.

The discrepancy I found was the new rollers that I received were complete with the shaft. The video with the older rollers instruct removing the rollers from the shaft.

To use the new rollers with the new shaft, requires removing an additional panel at both the front 2 and also the full back panel for the rear 2, to get a wrench on both ends of the shaft, and then attach the new roller bearing shaft assembly and re-install the panel.

Other than that, it went very smoothly and the result was a quiet rotating drum. No more thumping!

My dryer actually required 2 moisture sensors, but had only ordered one pack, which only came with 1 sensor. For whatever reason, I thought the pack would have had the 2 pieces.

Another reviewer made note to wear work gloves as some of the hardwares metal edges are quite sharp. Following that advice I completed the repair in 3 hours without a scratch. Thanks for the detailed video Partselect team and good luck to all attempting repairs.

HST code given by dryer
Called LG on the phone and they gave the button presses for diagnostics, which then gave the HST code, saying the Humidity sensor was bad.
The part was described as the Humidity sensor module. Actually it's just the wire leads for the sensor which must be electronic and only accessible by disassembling the dryer. There were descriptions about cleaning the wires, perhaps because some people use dryer sheets which cause a buildup on the wires and prevent them from doing their job. I use wool balls and have no buildup on my wires and replacing them did not fix the sensor, because the module accessible inside the dryer is not the moisture sensor, but only the wire leads.

Persistent smell of propane despite multiple duct cleanings.
Despite the young age of this dryer, and failure of all the other trials to fix the problem, I figured maybe the igniter is the problem. Ordered one. Followed a U tube video to take the unit apart. Noticed immediately that there was lots of lint pretty much everywhere inside the cabinet. Come to find that the blower and the vent had never been connected, with about two inches gap. So, some of the exhaust was going out the vent hose, but lots was not. In fact, lint had coated the propane jet and the air mixer assembly. Replacing the igniter was not particularly difficult, once the dryer was in lots of pieces. I did not test the igniter before replacing it. I did connect the vent outlet to the blower and secured it. End result was a perfectly functioning unit and a happy wife. I don't recall reading about this as a possible cause of propane odor and failure of the unit to heat up.

Dryer runs, no heat. Replaced thermostat and thermistor,ntc still no heat.
For model number DLE5977W
PartSelect logo
Hi Dave, Thank you for your question. So you have multiple thermostats and thermal fuses in your appliance. I would suggest testing all of those parts with a multi meter to see if they are working correctly. You can test them all with a multi meter, they should all read close to 0 ohms to be working correctly. You may also want to test your heating element itself as well. I hope that helps. Good luck with your repair.

My dryer cooling light always on and have no heating at all
For model number 796.80021900
PartSelect logo
Hi Ken, Thank you for your question. If the light is always on and there is no heat, then you may have an issue with the moisture sensing circuit. If this is the issue, you will need to test the dryer to see if it will heat and work properly in a time dry cycle. If the dryer is working properly, then you will need to check the sensor bars to see if there is any lint on them. If there is lint on them they will not detect any moisture. The bars are located on the lint screen. If they are clean, then you will need to check the control board and the wiring connected to it. I hope this helps. Thank you and have a great day!

My dryer start to work and 1-2 min shooting down. Looks like there is a shortage.I check control panel there is a light blinking flow sensor.
For model number DLG5966W
PartSelect logo
Hi Gary, Thank you for your question. If your dryer is shutting down too soon, the sensor does fix the issue the majority of the time. There are some other parts that you will need to check as well. You will need to check the thermostat, the lint filter and thermistor. I hope this helps. Thank you and have a great day!

Getting code d80 and h5. I cleaned all the air exhaust hose, wall ducts and vent outside. Still getting the code. I take the exhaust hose off the wall ducts and ran a test, the same code come up. When the dry is on the air coming out of the hose wasn’t warm, but the dryer is warm. What else can i do? I had a load of clothes in the dryer but they never got dry. What do you recommend?
For model number DLE1501W
PartSelect logo
Hi Jennifer, thank you for your question. The d80 error means the dryer is 80% clogged either in the air exhaust hose, wall ducts, or the vent outside. So if you have checked your entire system and your are still getting that error, you may have to start checking all of your thermostats. The first parts to check in this case would be all of your thermostats and thermal fuses. You can test those parts with a multi meter and they should be reading 0 ohms to be working correctly. If those parts are fine, you should then go on to testing your heating element as well. You can also test that with a multi meter and it should be reading between 0 - 50 ohms.I hope that helps. Good luck with your repair.

Hi, my dryer is not putting out any heat. "check filter" msg is on. I made sure the lint trap is clean and i vacuumed out under the lint filter. Check filter sign still on. Dryer repeatedly shuts off after about 5 minutes of running, but not heat at all during the 5 minutes it runs.Thank you for any guidance.
For model number DLEX3370V
PartSelect logo
Hello Susan, thank you for your question. First try unplugging the unit and letting it set for about 5 minutes, then plugging it back in to see if it will reset that light. We would recommend testing the thermostats in the unit, as most heat/non heating issues are cause by one or more thermostats. Here is some information on testing them. Set your multimeter to the R X 1 setting. Take each of your meter's probes and touch one to each terminal. You are testing for continuity, and you should receive a reading of either zero or infinity. At room temperature, testing the thermostat should produce a reading of zero. But if a thermostat is tested when it is heated to its limit, a reading of infinity should be produced. We strongly recommend that you test your thermostat at room temperature. If the test you conduct with your thermostat does not produce these results, then you should replace the component. If the thermostats are fine, check the moisture sensors to be sure they are not corroded or rusted and if they are replace them. I hope this helps!

The video covering the replacement of the moisture sensor is for an older model, which requires the removal of some wire connectors. On this model, two of the connectors that require removing the control panel are fixed (sealed) in place, which prevents lifting the panel out of the way.

Hi Bill, thank you for reaching out. We found a relevant video for your assistance. In the first five minutes of the video, the method of removing the control panel can be found. We hope this helps!

Hi Terry, thank you for the question. Based on our research, we would suggest replacing the high limit thermostat and thermistor kit, part number PS16878105. It monitors and helps regulate the dryer temperatures. We hope this solves your problem!

Dryer is not shutting off. Removed heat sensor before and cleaned it. But same thing is happening again. Should sensors be replaced? If so do you sell the whole sensor unit or only parts for it?
For model number DLG2702V
PartSelect logo
Hello Maryann, thank you for your question. The sensor bars are sold separately, and there are two in this unit. We would recommend replacing the bars to see if this will fix the issue, as cleaning them before, fixed the issue. We would recommend replacing both of them in the unit. If the issue persists, we would recommend testing the thermostats and the thermistor. I hope this helps!
