GE & Hotpoint Dryer Cycling Thermostat Parts — Models & Compatibility

Your GE or Hotpoint dryer is either running too hot and scorching clothes, or it's not heating at all. Both symptoms often point to the same culprit: a failed cycling thermostat. This hub covers the WE4M181 4-wire cycling thermostat that fits over 100 GE, Hotpoint, RCA, and Kenmore dryer models — the workhorse part that regulates your dryer's temperature throughout the cycle.

Is This the Right Part for Your Model?

The WE4M181 works across multiple GE-manufactured dryer lines, including GTX, GTD, PTM, DCX, DWX, DRS, DPS, DBX, DHD, DJX, DLS, DBL series, plus many Hotpoint HTD models. You'll find your model number on a label inside the door opening or on the back panel near the power cord. Common compatible models include GTX18GSSJ1WW, GTDX400ED4WS, PTMX910EM1WW, HTDX100GD4WW, and dozens more across the GTD, DRS, and DBX families.

About This Replacement Part

The cycling thermostat is what keeps your dryer from overheating or running cold. It's a 4-wire bi-metal sensor mounted to the blower housing that opens and closes contacts based on temperature — telling the heating element when to fire and when to rest. When it fails, you'll notice clothes coming out either damp and cold or dangerously hot with scorch marks. This thermostat replaces original part numbers AP2044414, WE4M245, WE04M0181, and PS267926. At $35.99, it's the exact OEM-spec part that restores proper temperature regulation across all compatible GE and Hotpoint models. One customer who's ordered multiple parts from us over the years noted: "This was exactly the part we needed... always impressed with how quickly our part is shipped and delivered."

Common Models Using This Thermostat

This cycling thermostat appears across GE's electric dryer lineup from the early 2000s through mid-2010s models. You'll find it in residential GTX and GTD series dryers, commercial-grade PTM models, and Hotpoint's HTD line. It's the same part whether you have a basic white GE dryer or a stacked Hotpoint unit — GE used this thermostat design across their entire electric dryer manufacturing run for nearly two decades.

Why GE & Hotpoint Cycling Thermostats Fail

Lint buildup around the blower housing causes the thermostat to read false temperatures and cycle erratically. Over thousands of heating cycles, the bi-metal contacts inside wear out and either stick closed (causing overheating) or fail to close properly (no heat). Restricted airflow from clogged vents makes the problem worse — the thermostat works overtime trying to regulate temperatures that shouldn't be that high in the first place. If your dryer has been running hot for months before finally going cold, the thermostat contacts have likely welded themselves together and then burned out completely.

What You'll Need for Replacement

Replacing the cycling thermostat requires basic tools: a 1/4" nut driver or socket set, needle-nose pliers for the wire terminals, and about 30 minutes. You'll need to pull the dryer away from the wall, disconnect power, remove the front or top panel depending on your model, and access the blower housing where the thermostat mounts. The hardest part isn't the swap itself — it's remembering which wire goes where on those four terminals. Take a photo before you disconnect anything.

Verify Before You Order

Match your model number against our compatibility list — this thermostat works with GE, Hotpoint, RCA, and some Kenmore models manufactured by GE. If your model starts with GTX, GTD, PTM, DCX, DRS, DPS, DBX, DHD, DJX, DLS, DBL (GE) or HTD (Hotpoint), you're likely good. Kenmore models in the 600-series that were GE-built also use this part. When in doubt, check the existing thermostat label on your dryer — if it says WE4M181, WE4M245, or any number starting with WE4M or WE04M, this replacement will work.
