Oven Not Holding Temperature? GE Thermostat Control Knob WS01L06055 – Fix Inaccurate Baking Fast
If your GE range oven won't hold temperature, runs too hot, or bakes unevenly, a worn thermostat control knob is the most common cause. In most GE and Hotpoint ranges, the thermostat knob is the primary interface between the user and the oven's temperature regulation system. When it fails or wears out, the oven may overshoot or undershoot set temperatures, making consistent cooking impossible. ⚡ Common failure point in GE-built ranges and ovens. Part WS01L06055 is the genuine OEM replacement that restores accurate temperature control and consistent oven performance.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Your range powers on and the burners/elements function normally
- ✔ The oven light, timer, and other controls work correctly
- ✔ Electrical supply to the range is confirmed OK
- ✔ ONLY problem is inaccurate oven temperature or a damaged/missing control knob

🔧 Common Symptoms

- Baked goods consistently over- or under-cooked
- Thermostat knob spins freely, feels loose, or is cracked/broken
- Knob markings worn off — difficult to set accurate temperature
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this thermostat control knob restores normal oven operation immediately.

⚙️ Installation
Skill Level: EASY — 5 to 10 minutes. Disconnect power before servicing. Pull the old knob straight off the thermostat shaft, align the D-shaped bore of the new knob WS01L06055 with the shaft flat, and press firmly until seated. No tools required in most installations.

💡 Pro Tip
Before installing the new knob, inspect the thermostat shaft for wear or stripping. If the shaft is damaged, the knob will not seat properly and temperature control will remain unreliable. A damaged shaft indicates the thermostat itself may need replacement — address the shaft first to avoid a repeat service call.
