XPARTCO 6931EL3001F Dryer Hi-Limit Thermostat
The XPARTCO 6931EL3001F is an aftermarket replacement dryer rear hi-limit heater thermostat compatible with select LG and Kenmore electric and gas dryers. The hi-limit thermostat is a safety switch mounted on the heater housing that monitors the temperature at the heating element. If the heater temperature exceeds the safe operating limit, the thermostat opens its contacts to cut power to the heating element, protecting the dryer and its contents from overheating. When cooled, the thermostat resets automatically — but if it fails internally, it may remain open permanently, causing the dryer to produce no heat despite the thermal fuse and other components being intact.
Rated L125-31C, 250V, 25A, this 3-terminal thermostat measures 2"L x 1-3/4"W x 1-1/4"H with approximately 1-5/8" between mounting holes (center to center). It is constructed from metal and plastic in gray/black and mounts directly on the heater housing. It directly replaces 1377779, AP5072172, AH3530482, EA3530482, EAP3530482, PS3530482, and PD00023316. Often replaced together with the 6931EL3003D thermal fuse — both mount on the heater housing and work as a system to protect the dryer from overheating. Installs in 15–20 minutes with basic hand tools.

Often replaced together with 6931EL3003D thermal fuse. Replaces 1377779, AP5072172, AH3530482, EA3530482, EAP3530482, PS3530482.
Common Problems This Part Fixes
Dryer produces no heat — hi-limit thermostat has failed open and is permanently interrupting the heater circuit
Dryer takes much longer than normal to dry a load
Dryer tumbles normally but generates no heat during the cycle
No heat even after the thermal fuse has already been replaced — thermostat also failed
Dryer overheating intermittently — thermostat not opening at the correct temperature
Multimeter test shows open circuit (no continuity) across the thermostat at room temperature

Tip: When replacing the 6931EL3001F thermostat, also replace the 6931EL3003D thermal fuse at the same time. Both mount on the heater housing and are commonly replaced together — an overheating event that causes one to fail typically stresses both.
Key Features
Hi-limit heater thermostat — safety switch that cuts power to the heating element if heater temperature exceeds safe limits
Auto-resets when cooled — but a failed thermostat that remains open causes permanent no-heat
Rated L125-31C, 250V, 25A — correct specifications for compatible LG and Kenmore dryers
3-terminal design — matches the original wiring configuration on compatible heater housings
Dimensions: 2"L x 1-3/4"W x 1-1/4"H; ~1-5/8" between mounting holes (center to center)
Metal and plastic construction (gray/black) — heat-resistant materials for heater housing application
Mounts directly on the heater housing — accessible from the dryer back panel
Often replaced together with 6931EL3003D thermal fuse for a complete heater housing thermal repair
Test with multimeter before replacing — should show closed continuity at room temperature
Aftermarket replacement built to OEM-equivalent quality standards
Quick DIY repair — installs in 15–20 minutes with basic hand tools

Installation Notes
⚠️ Unplug Dryer and Shut Off Gas Before Starting Disconnect power (and shut off gas for gas dryers) before beginning. Remove the back panel of the dryer by unscrewing the perimeter screws to access the heater housing. The 6931EL3001F thermostat is mounted on the heater housing — it is the 3-terminal component with gray/black housing. Before removing it, test it with a multimeter: disconnect the wires and probe the terminals. At room temperature a working thermostat shows closed continuity. An open reading confirms failure. Photograph the 3-wire connections before disconnecting — reconnecting in the correct positions is important. Remove the 2 mounting screws and lift the old thermostat off. Install the new thermostat in the same position with the 2 mounting screws and reconnect the wires in the same positions. While the heater housing is accessible, also test and replace the 6931EL3003D thermal fuse if needed. Reinstall the back panel, restore power, and run a test heat cycle. Tools needed: Phillips screwdriver, multimeter.
Frequently Asked Questions
What is the difference between the 6931EL3001F thermostat and the 6931EL3003D thermal fuse?
Both are mounted on the heater housing and protect the dryer from overheating, but they work differently. The 6931EL3001F is a resettable hi-limit thermostat rated L125-31C — it opens when the heater temperature gets too high and resets automatically when cooled. The 6931EL3003D is a one-time thermal fuse that permanently interrupts the circuit if the temperature exceeds its rated limit — once blown, it cannot reset and must be replaced. Both should show closed continuity at room temperature when working. Because both are on the heater housing and experience the same thermal stress, replacing both at the same time is recommended.
How do I test the 6931EL3001F thermostat with a multimeter?
Unplug the dryer and disconnect all three wires from the thermostat terminals. Set your multimeter to continuity or resistance mode. At room temperature, a working 6931EL3001F thermostat should show closed continuity (near-zero resistance) across its contacts. If your multimeter reads open circuit (no continuity / OL), the thermostat has failed and needs replacement. Since this thermostat auto-resets when cooled, always test at room temperature — testing while the dryer is still warm may give a false open reading if the thermostat has legitimately opened due to heat.
My LG dryer has no heat but the thermal fuse is good — could it be the thermostat?
Yes — when the thermal fuse tests good but there is still no heat, the hi-limit thermostat (6931EL3001F) is the next most common culprit. A thermostat that has failed internally may remain permanently open even at room temperature, cutting power to the heating element exactly as a blown thermal fuse would. Test the thermostat with a multimeter for continuity. Also check the cycling thermostat (6931EL3002M) and the thermistor (6323EL2001B) — all three are part of the LG dryer thermal control system and any one of them can cause a no-heat condition.
What does the "L125-31C" rating mean?
The L125-31C rating describes the thermostat's operating parameters. L125 means the thermostat opens (trips) when the temperature reaches approximately 125°C (257°F). The 31 indicates the reset differential — the thermostat resets when the temperature drops approximately 31°C below the trip point, around 94°C (201°F). This rating ensures the thermostat allows the heater to operate at normal drying temperatures while protecting against dangerous overheating.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine LG OEM part, but is manufactured from metal and plastic to match the L125-31C rating, dimensions, and 3-terminal configuration of the original 6931EL3001F hi-limit heater thermostat.
