LG DLGX5681V dryer Parts

LG gas dryers such as model DLGX5681V do not use a homeowner “gas regulator reset button.” If your dryer is not heating, the correct reset is to restore safe operating conditions (gas supply on, proper airflow, and power reset), then run a heat cycle and confirm the burner ignites as described in the DLGX5681V owner's manual.

Safe reset steps for “no heat” on a gas dryer

• Turn the dryer Off, then unplug it (or switch the breaker off) for 1 minute.
• Confirm the house gas shutoff and the dryer gas shutoff are fully open.
• Clean the lint filter before the next test run; a clogged filter can cause poor drying and overheating.
• Check the vent path for restrictions; use heavy metal venting (not plastic or thin foil duct).
• Restart the dryer on a heat setting and watch for ignition.

What “normal ignition” looks like on DLGX5681V

When you start a heated cycle, the igniter should light the main burner. If air is still in the gas line (common after installation or a gas interruption), the igniter may shut off before the burner lights and then reattempt ignition.

What you observe	What it usually means	What to do next
Igniter glows, then burner lights	Normal operation	Let it run and verify warm exhaust
Igniter glows, no flame, repeats	Air in line or gas supply issue	Confirm shutoffs open; retry cycle
No igniter glow at all	Electrical/control or safety circuit issue	Check power; then move to diagnostics

Why it matters

Gas dryers rely on correct gas flow and proper airflow. A restricted vent can trigger high temperatures and shutdowns, and gas supply issues can prevent ignition even when the dryer tumbles.

Parts that commonly relate to “no heat” symptoms

If troubleshooting points to a failed component, these are common heat-system parts for DLGX5681V:

• Dryer burner igniter 5318EL3001A (ignites the gas)
• Dryer thermistor AGM30045804 (temperature sensing)
• Dryer high-limit thermostat 6931EL3003C (overheat safety)

The most common problem we see with LG dryers (including model DLGX5681V) is restricted airflow from lint buildup or a clogged exhaust vent. Poor airflow causes long dry times, overheating, and airflow alerts; it can also contribute to heat-related shutdowns and error conditions.

Quick checks that fix most “LG dryer not drying” complaints

• Clean the lint filter before every load; never run the dryer without it installed.
• Inspect the vent hood outside; confirm the flap opens strongly while the dryer runs.
• Check the entire vent run for crushed ducting, lint blockage, or excessive length.
• Use heavy metal venting (not plastic or thin foil duct).
• Avoid overloading; heavy fabrics and large loads dry slower even when the dryer is working normally.

What your DLGX5681V is designed to tell you

Your DLGX5681V includes a duct blockage sensing system that detects restricted household ductwork and alerts you when exhaust airflow is reduced. When you see an airflow restriction alert, the fix is to clean or repair the ducting to remove the restriction (details and safety guidance are in the owner's manual).

Common symptoms and the most likely cause

Symptom	Most common cause	What to do first
Clothes take too long to dry	Lint filter dirty; exhaust ducts blocked/too long	Clean filter; clear/shorten vent run
Dryer shuts off or seems to “overheat”	Airflow restriction	Check venting and outside hood airflow
No heat on gas model	Gas supply off; airflow issues; failed heat-safety parts	Confirm gas is on; then check venting
tE1/tE2 error	Thermistor problem	Test/replace the thermistor

Parts that often come up when airflow or heat problems persist

If venting is clear and dry times are still long, these model-matched parts are commonly involved in temperature control and safety:

• Dryer thermistor AGM30045804 (can relate to tE1/tE2)
• Dryer blower thermostat 6931EL3002M
• Dryer high-limit thermostat 6931EL3003C

Why it matters

Restricted airflow is the root cause behind many LG dryer complaints because it reduces drying performance and forces the dryer to run hotter than intended. Keeping the lint filter and exhaust ducting clean improves efficiency, shortens cycle times, and helps protect key components like thermostats and sensors.

On your LG DLGX5681V dryer, the model number is printed on the rating plate inside the front door. Open the dryer door and look along the door opening area for the label that lists both the model and serial number; confirm the characters match exactly.

Where to look (fast checklist)

• Open the dryer door fully.
• Look for a rating plate or data label on the inside front opening.
• Find the line labeled Model (it should read DLGX5681V).
• Record the Serial number too; it helps match the correct diagrams and parts.
• Use the exact model number when ordering parts or checking troubleshooting steps in the DLGX5681V owner's manual.

What the rating plate typically includes

Label item	What it’s used for
Model number	Ensures correct parts and service info for DLGX5681V
Serial number	Identifies production details and version changes
Electrical and gas info	Confirms power and fuel requirements

Why it matters

LG dryers can have similar-looking models (for example, DLGX and DLEX versions) with different components like the electronic control board, thermistors, or drum belt. Using the exact model number prevents ordering the wrong part and helps you follow the right troubleshooting steps.
