What is the most common problem with LG dryers?
The most common problem we see with LG dryers like model DLE3733W is poor drying performance caused by restricted airflow (lint buildup in the filter housing, exhaust duct, or vent). Airflow restrictions can also lead to overheating symptoms such as cycle shutoffs and longer dry times; the DLE3733W owner's manual troubleshooting section covers these basics.
- Clothes take too long to dry: venting restriction, crushed duct, or lint blockage
- Dryer gets very hot or shuts off early: overheating from poor airflow; sometimes a thermostat issue
- Dryer tumbles but no heat: power supply issue (common on electric dryers) or a failed heater component
- Loud squealing, thumping, or grinding: worn belt, idler pulley, or drum support parts
- Stops mid-cycle or gives an error code: airflow, temperature sensing, or control-related issue
- Clean the lint screen and the lint screen housing.
- Inspect the vent path from the dryer to the outside hood for kinks, crushing, or heavy lint.
- Confirm strong airflow at the outside vent hood while the dryer runs.
- For electric models, check that both breakers/fuses are on; many dryers can run but not heat on a partial power loss.
- If the dryer will not start, verify the outlet connection and reset the breaker.
When airflow is good but symptoms continue, these are frequent suspects:
| Symptom | Likely system | Example part for DLE3733W |
|---|---|---|
| No heat (electric) | Heating circuit | Dryer heating element 5301EL1001J |
| Overheats or temp swings | Temperature sensing | Dryer thermistor AGM30045804 |
| Overheats, shuts down | Safety temperature limit | Dryer blower thermostat 6931EL3002M |
| Squeals or drum won’t turn | Drum drive | Dryer drum belt 4400EL2001F |
Restricted venting is more than an inconvenience; it drives up dry times and can trigger high-temperature safety controls. Fixing airflow first often restores normal drying and helps protect key components like the heating element, thermostats, and motor.
For error-code related problems, we use the LG dryer error codes guide to match the code to the most likely airflow, sensor, or heating issue.

Do you have to hook up water to a LG steam dryer?
Yes, you need a cold-water hookup to use the steam features on an LG steam dryer; on the LG DLE3733W, you can still run normal drying cycles without water, but any steam option will not work until the water line is connected. See the DLE3733W owner's manual for the exact hookup method and cycle details.
You only need water when you plan to use steam-enhanced cycles or options.
- Water required: Steam Refresh, Steam Wrinkle Care, TurboSteam (names vary by cycle set)
- Water not required: Timed Dry, most standard sensor dry cycles (as long as steam is not selected)
- Best practice: Leave steam options off until the water line is installed
Most LG steam dryers connect to the washer's cold-water supply using a Y-connector and a short inlet hose to the dryer.
- Shut off the cold-water valve before installing the adapter
- Use the cold-water line (steam uses cold water that the dryer heats internally)
- Check for leaks at every connection after turning water back on
- Keep the hose routed so it does not kink or rub on sharp edges
If the dryer runs but steam cycles do not perform correctly, these are the most common causes.
| Symptom | Most likely cause | What to check first |
|---|---|---|
| No steam during a steam cycle | Water valve is off | Confirm the cold-water valve is fully open |
| Weak steam or long steam cycle | Low water pressure or kinked hose | Straighten hose; verify steady flow |
| Steam option selected but results are poor | Load size or fabric type mismatch | Use smaller loads; follow cycle guidance |
| Dryer heats but steam errors appear | Sensor or control issue | Review LG dryer error codes and follow the steps listed |
Steam features rely on a consistent water supply; without it, the dryer can still tumble and heat normally, but steam cycles cannot add moisture to relax wrinkles or refresh fabrics. Connecting water also helps you get the full performance you paid for.
If you are also repairing the dryer while setting it up, common wear items for the DLE3733W include the dryer drum belt 4400EL2001F. You can order replacement parts from the parts list for this model, or search by model number on Sears PartsDirect.

What is the average lifespan of an LG dryer?
Most LG dryers, including the LG DLE3733W, typically last 10 to 15 years with normal household use and basic maintenance. Consistent airflow care (lint screen and venting) and fixing small issues early usually makes the biggest difference in how long the dryer runs reliably.
A dryer’s life is driven more by heat and airflow conditions than by brand alone.
- Vent and lint maintenance: restricted airflow overheats components and shortens life
- Load habits: frequent overloading strains the drum, belt, and motor
- Heat control health: failed thermostats or sensors can cause overheating or no-heat cycles
- Noise and friction: worn rollers, idler pulleys, or seals increase wear on the motor
- Electrical supply (electric models): poor connections can cause intermittent heating
Use this routine to help your DLE3733W reach the upper end of the 10 to 15 year range.
- Clean the lint screen every load
- Inspect and clean the vent path regularly; keep the run short and unobstructed
- Do not overload; leave room for tumbling
- Stop using the dryer if you smell burning or notice repeated overheating
- Address squealing, thumping, or scraping early (often belt, idler, or rollers)
If the dryer runs but gets noisy, stops tumbling, or dries poorly, these are frequent culprits.
| Symptom | Common cause | Example part for DLE3733W |
|---|---|---|
| Drum not turning | Worn/broken belt | Dryer drum belt 4400EL2001F |
| Squealing or tension issues | Worn idler pulley | Dryer idler pulley 4560EL3001A |
| No heat or overheating | Heating or temperature control issue | Dryer heating element 5301EL1001J |
A dryer that runs hot because of poor airflow can prematurely wear the heating element, thermostats, and motor. Keeping exhaust airflow strong is the simplest way to protect performance, drying time, and long-term reliability.
For model-specific specs and care guidance (including size and operating details), use the owner's manual. If you need to purchase replacement parts beyond the list shown for this model, search by model number on Sears PartsDirect.

How do I hard reset my LG dryer?
To hard reset your LG DLE3733W dryer, we recommend disconnecting power for a full 1 minute, then restoring power and starting a new cycle. This clears many control glitches and forces the dryer to reboot its control board.
- Press Power to turn the dryer off.
- Unplug the dryer (or switch the dryer breaker OFF).
- Wait 1 minute.
- Plug back in (or switch the breaker ON).
- Press Power, select a cycle, then press Start/Pause.
For cycle and Start/Pause behavior (including the 10-minute auto shutoff after selecting a cycle), follow the DLE3733W owner's manual.
A reset will not fix a failed safety device or a mechanical problem. Check these common causes:
- Door not fully closed or latch issue; the dryer will not start if the door switch is not made.
- Overheating from restricted venting; clean the lint screen and confirm strong airflow at the outside vent.
- Temperature sensing problem; a failed thermistor can cause odd heating or cycle behavior.
- Drive system issue; a broken belt or seized pulley can prevent tumbling.
- Control knob damage; a cracked knob can keep you from selecting a cycle correctly.
| Symptom you notice | Part to consider (for DLE3733W) | What it affects |
|---|---|---|
| Dryer runs but drum does not turn | Dryer drum belt 4400EL2001F | Drum drive |
| Squealing, binding, or intermittent tumbling | Dryer idler pulley 4560EL3001A | Belt tension and drum rotation |
| Heat is erratic or cycles end too soon | Dryer thermistor AGM30045804 | Temperature sensing |
A proper hard reset is a fast first step because it clears temporary control logic errors. If the problem returns immediately, focusing on airflow, door closure, and key components like the belt, idler pulley, and thermistor helps you move from “resetting” to a real fix.
You can order the correct replacement parts for LG DLE3733W from the parts list for this model, or search by model number on Sears PartsDirect.
