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.
What's In The Set
| Component | Type | Function |
|---|---|---|
| 8557403 High-Limit Thermostat | Auto-resetting | Cuts power to the heating element if temperature exceeds safe limits, resets automatically once the dryer cools. |
| 8318314 Thermal Fuse | One-time, non-resettable | Backup safety device — permanently opens the circuit if temperature exceeds safe limits. Must be replaced once blown. |
Common Problems This Set Fixes
- Dryer runs but produces no heat at all
- Dryer won't start at all — no lights, no tumble, no response
- Drying takes noticeably longer than it used to
- Dryer overheating before shutting down
- Dryer that stopped working suddenly after running unusually hot
- Repeated thermal fuse failures on a dryer with a known venting issue

Installation Notes
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.
