XPARTCO 280148 Dryer Thermostat Set
The XPARTCO 280148 is an aftermarket replacement thermal fuse and high-limit thermostat set for Whirlpool electric dryers, and also fits select Kenmore, Maytag, Amana, Roper, Estate, Crosley, Admiral, KitchenAid, and Norge models. This set bundles the 8557403 high-limit thermostat, which monitors temperature and automatically cuts power to the heating element if it overheats, then resets itself once the dryer cools, together with the 8318314 thermal fuse, a one-time backup safety device that permanently opens the circuit if temperatures climb high enough that the thermostat alone doesn't prevent an overheat.
These two parts are sold together and commonly fail around the same time, since they protect the same circuit and respond to the same underlying overheating conditions — most often restricted exhaust venting. Symptoms include the dryer not heating at all, taking longer than normal to dry a load, or overheating before shutting down. It directly replaces 280148VP, 1175772, AP3874047, PS991443, EAP991443, and 314634.
Quick Answer
The XPARTCO 280148 Dryer Thermostat Set fixes Whirlpool, Kenmore, Maytag, Amana, Roper, Estate, Crosley, Admiral, KitchenAid, and Norge electric dryers with no heat, drying that takes too long, or a dryer that overheats before shutting down. Includes the 8557403 high-limit thermostat (auto-resetting) and 8318314 thermal fuse (one-time). Replaces 280148VP, 1175772, AP3874047, PS991443, EAP991443, 314634. Always inspect and clean the exhaust venting when replacing this set — a blown thermal fuse is a symptom of restricted airflow, and skipping the vent check leads to repeat failures.

Installation Notes
⚠️ Unplug Dryer Before Starting — Inspect And Clean The Venting Before Reassembling Disconnect power at the outlet or shut off the circuit breaker before beginning. Wear work gloves. Access is typically through the rear panel, near the heating element and blower housing where both components are mounted. Photograph the wiring connections before disconnecting anything, since the thermostat and fuse can be easy to swap positions by mistake. Remove each old component from its mounting position, noting orientation, and disconnect its wiring. Before reassembling, fully inspect and clean the dryer's exhaust vent, from the lint trap housing all the way to the exterior vent hood, checking for lint buildup, crushed sections, or excessive length. Restricted airflow is the leading cause of failure for both of these components, and skipping the vent check often leads to repeat failures even with new parts installed. Install the new 8557403 thermostat and 8318314 thermal fuse from this set in the same positions as the parts they replace, reconnecting wiring exactly as photographed. Reassemble the panel, restore power, and run a full test cycle to confirm normal, consistent heating with no premature shutoffs. Tools needed: Phillips or nut driver (model-dependent), work gloves.
Frequently Asked Questions
Why replace both the thermostat and the fuse together instead of just the one that failed?
These two parts protect the same circuit at different thresholds and tend to fail from the same underlying cause. If the high-limit thermostat isn't regulating temperature correctly, the thermal fuse often ends up blowing as the backup safety measure. Replacing only one risks the other failing again shortly after, so they're sold and serviced together as a set.
I replaced this set and the dryer failed again. What should I check?
This is a strong sign the underlying cause — almost always restricted airflow — was never addressed. Thoroughly inspect and clean the entire exhaust path from the lint trap housing to the outside vent hood, checking for lint buildup, crushed or kinked ductwork, or a vent run that's too long. Failing to correct a venting issue will cause repetitive failures of this set even when it's brand new.
Should I replace the heating element at the same time?
It's worth considering if your dryer's heating element (commonly WP8544771 on compatible models) is original and has been running alongside a failing thermostat, since sustained overheating can stress the element as well. It's not required, but since you'll already have the panel open for this repair, it's a reasonable time to inspect the element for visible damage.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured to match the temperature thresholds and mounting configuration of the original 280148 high-limit thermostat and thermal fuse set used in compatible Whirlpool, Kenmore, Maytag, Amana, Roper, and related electric dryers.
