Whirlpool LG7681XSW3 gas dryer Parts

A Whirlpool gas dryer like model LG7681XSW3 typically pulls about 3 to 6 amps on a 120V circuit during normal operation. The electricity mainly powers the drive motor, timer or control, and igniter system; the heat itself comes from gas.

What affects amp draw on LG7681XSW3

• Motor starting surge: brief higher draw when the drum first starts turning
• Igniter on-time: the igniter draws power only while lighting the burner
• Cycle selection: longer run time does not increase amps, it increases total energy used
• Airflow restrictions: a clogged vent can make the dryer run longer (same amps, more time)
• Component problems: failing parts can change how long the igniter or motor runs

Quick troubleshooting if you suspect an electrical issue

• Confirm the dryer is on a dedicated 120V outlet and the plug fits tightly.
• If the drum will not turn, check for a broken belt such as the drum belt 341241.
• If the dryer runs but will not heat, common gas-heat suspects include the dryer igniter 279311 and dryer valve coil kit 279834.
• If the dryer will not start at all, a failed dryer door switch W10820036 can prevent operation.

Typical electrical expectations (gas vs. electric)

Dryer type	Typical voltage	Typical running amps	What electricity powers
Gas dryer (like LG7681XSW3)	120V	3 to 6 A	Motor, controls, igniter
Electric dryer	240V	20 to 30 A	Heating element plus motor/controls

Why it matters

Knowing the expected amp draw helps you choose the right circuit and diagnose symptoms. A gas dryer that repeatedly trips a breaker or blows a fuse usually points to a wiring issue, motor problem, or a shorted component rather than “normal” power use.

Whirlpool Duet steam dryers most often have steam-system faults (no steam, leaks, or steam errors), long dry times from restricted venting, and intermittent heat. Your Whirlpool LG7681XSW3 is a gas dryer; it shares airflow and gas-heat issues, but it does not use the same Duet steam components.

Common Duet steam dryer problems (steam-specific)

• No steam or weak steam: clogged steam nozzle, restricted water supply, failed steam valve
• Steam leaks: loose hose connections, damaged inlet hose, mineral buildup at fittings
• Steam cycle stops or errors: steam valve not opening, wiring/connector issues, control sensing problems
• Wrinkles not improving: steam not generating, cycle selection, overloading

Common problems that affect both steam and non-steam dryers

• Long dry times: blocked vent, crushed flex duct, clogged lint screen, blocked outside hood
• Dryer runs but no heat (gas models): ignition system failure (igniter, radiant sensor, gas valve coils)
• Won’t start: door switch not closing, motor switch issue, power supply problems

Quick checks we recommend first

• Clean the lint screen and confirm strong airflow at the outside vent hood.
• Run a timed dry test; if heat drops out, focus on the gas ignition components.
• For steam models, verify the water supply valve is fully open and hoses are not kinked.
• Check for error codes and match them to the symptom.

Parts on LG7681XSW3 that commonly solve “no heat” or “won’t start”

Symptom on LG7681XSW3	What usually fails	Example part for this model
No heat or heat cuts out	Gas valve coils	Dryer valve coil kit 279834
No ignition	Igniter	Dryer igniter 279311
Ignites then shuts off	Radiant sensor	Dryer radiant sensor WP338906
Won’t start	Door switch	Dryer door switch W10820036

Why it matters

Steam problems point to the water and steam delivery system, while long dry times and no-heat complaints are usually venting or burner ignition issues. Separating steam symptoms from gas-heat symptoms speeds up troubleshooting and prevents unnecessary part replacement.

The Whirlpool gas dryer model LG7681XSW3 is a full-size 27-inch platform; these dryers typically run about 6.5 to 7.4 cu. ft. of drum capacity. Use that range to plan load size, then fine-tune by leaving enough tumbling room for good airflow.

How to size loads for this dryer

For best drying performance on LG7681XSW3, we recommend these practical load rules:

• Fill the drum about 1/2 to 2/3 full for even drying
• Leave space at the top so items can tumble freely
• Dry bulky items (comforters, jackets) alone or with a few small items
• Split heavy loads (towels, jeans) into two smaller loads to reduce damp spots
• If cycles run long, check venting and airflow before assuming the load is too large

Quick capacity guide (typical full-size dryer planning)

Dryer size class	Typical capacity range	What it handles well
Compact (24-inch)	3.4 to 4.4 cu. ft.	Small loads, tight spaces
Full-size (27-inch)	6.5 to 7.4 cu. ft.	Most household loads, queen bedding
Extra-large	7.4+ cu. ft.	Very bulky items, large families

Why it matters

Capacity is really about tumbling space and airflow. When loads are packed tight, a gas dryer can heat but still dry unevenly because air cannot move through thick fabrics.

Parts that affect “usable capacity” (tumbling and airflow)

If the drum slips or airflow is weak, loads behave like the dryer is smaller than it is.

• Drum belt 341241: keeps the drum turning at the correct speed
• Dryer blower wheel WP694089: moves air through the drum and out the exhaust
• Dryer idler pulley WP691366: maintains belt tension so the drum tumbles consistently
