Oven Not Heating to the Right Temperature? GE Oven Control Thermostat WS01F02660 – Fix Temperature Failure Fast
If your GE range oven runs too hot, too cold, or fails to hold temperature, the control thermostat is the most common cause. In most GE Profile and GE Café ranges, this is caused by a failed oven control thermostat. When it fails, the oven cannot regulate heat accurately — resulting in undercooked or overcooked food, error codes, or a completely unresponsive bake/broil cycle. ⚡ Common failure point in GE-built freestanding and slide-in ranges. Part WS01F02660 is the genuine OEM replacement that restores precise temperature regulation and normal oven operation.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ QUALIFIER 1 — appliance powers on and the display functions normally
- ✔ QUALIFIER 2 — burners and other cooktop functions work correctly
- ✔ QUALIFIER 3 — oven ignites or heats but temperature is inaccurate or unstable
- ✔ ONLY problem is oven temperature not reaching setpoint or cycling incorrectly

🔧 Common Symptoms
- Oven runs significantly hotter or cooler than the set temperature
- Bake or broil cycle starts but shuts off prematurely
- Oven takes excessively long to preheat or never reaches setpoint
- F3 or temperature-related error codes displayed on the control panel
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this oven control thermostat restores normal operation immediately.
📦 Part Details

⚠️ Recommended While Repairing:
While the oven is open, inspect the oven temperature sensor (RTD probe) — a failing sensor can mimic thermostat symptoms and cause a repeat failure. Replacing both at the same time eliminates the most common root causes in a single service call.

⚙️ Installation
Skill Level: MODERATE — 30–45 minutes. Disconnect power before servicing. Remove the rear panel or control console to access the thermostat mounting location, disconnect the wiring harness, swap the thermostat, and reassemble. Calibrate oven temperature after installation if your model supports it.

💡 Pro Tip
Test Before You Replace:
Use an oven thermometer to verify the actual cavity temperature vs. the setpoint before ordering. A 25–35°F offset that is consistent across temperatures typically points to the thermostat or sensor — not the control board. This saves you from replacing the more expensive board unnecessarily.
