LG Dryer Not Heating or Overheating? Thermostat 6931EL3003C – Fix Thermal Fuse Failures Fast

If your LG gas dryer produces no heat, overheats, or keeps blowing the thermal fuse, a failed cycling thermostat is the most likely cause. In most LG-built gas dryers, the cycling thermostat monitors exhaust air temperature and cycles the burner on and off to maintain the correct drying temperature. When it fails open, the burner never activates and the dryer runs cold; when it fails closed, the burner runs continuously, overheats the drum, and blows the thermal fuse. ⚡ A failed cycling thermostat is the most common root cause of repeat thermal fuse failures on LG gas dryers. Part 6931EL3003C is the genuine OEM replacement that restores accurate temperature cycling, directly superseding AGM30045804 and 6931EL3004B with no modification required.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dryer powers on and drum rotates normally
• ✔ Gas supply is confirmed on and the igniter has been tested
• ✔ Thermal fuse has been tested and replaced if blown — but the dryer still won’t heat or overheats again
• ✔ Exhaust duct and exterior vent are clear of lint blockage
• ✔ ONLY problem is no heat, insufficient heat, overheating, or thermal fuse blowing repeatedly after replacement

🔧 Common Symptoms

• Dryer runs but produces no heat — clothes come out damp after a full cycle
• Dryer takes 2–3 cycles to dry a normal load — insufficient heat output
• Thermal fuse blows repeatedly after replacement — thermostat failing closed
• Dryer overheating — clothes or drum excessively hot to the touch
• Dryer shuts off mid-cycle due to thermal overload
• Burning smell during operation — burner running without cycling off

✔ If these symptoms match, the cycling thermostat is the most likely failed component in the system.

✔ In most cases, replacing the thermostat restores normal heat cycling and drying performance immediately.

📦 Part Details

• Part Number: 6931EL3003C
• Type: Dryer cycling thermostat — monitors exhaust air temperature and cycles the gas burner on and off to maintain correct drying temperature
• Replaces: OEM direct-fit thermostat — supersedes AGM30045804, 6931EL3004B (no modification required)
• Brands: LG

⚙️ Installation

Skill Level: EASY — 15 to 25 minutes. Disconnect power to the dryer at the breaker and turn off the gas supply before starting. The cycling thermostat is located on the exhaust duct or burner housing inside the dryer cabinet — access it by removing the rear panel or lower front panel depending on model. Disconnect the two wire terminals, remove the mounting screw, and install the new 6931EL3003C in the same position. Reconnect the terminals, reassemble the panel, restore power and gas, and run a heat cycle to confirm normal operation. Do not overtighten the mounting screw — the thermostat housing is plastic and cracks easily.
