📋 Step-by-Step Instructions
Turn off power at breaker
Locate the temperature sensor inside the oven (usually back wall, top corner)
Remove the mounting screw and pull sensor through the hole
Disconnect the wire harness
Test resistance with multimeter — should read ~1080 ohms at room temp
If reading is way off, replace the sensor
Push new sensor into place and secure
Don't put this off.

🔍 Why This Happens
Root cause analysis for your oven / range's not reaching temperature
The oven temperature sensor in your oven / range has degraded or accumulated residue that prevents accurate readings. Sensors work by detecting a physical change (temperature, flame, position) — when they're coated in carbon, mineral scale, or corrosion, they send false signals or no signal at all. Cleaning the sensor often restores function temporarily, but replacement is the reliable fix.

🛡️ Prevention Tips
How to prevent your oven / range's not reaching temperature from happening again after this repair.
Clean spills promptly after the oven cools. Baked-on food and grease can damage heating elements and sensors over time.
Avoid using the self-cleaning feature frequently — it heats the oven to extreme temperatures that stress elements, wiring, and thermal fuses.
For gas ranges, keep the burner caps and igniter ports clean. Food debris on the igniter is the most common cause of ignition failure.
Don't slide heavy pots across coil elements — this damages the terminals and can cause intermittent connections.
When replacing a sensor, avoid touching the sensing element with bare hands. Oils from your skin can coat the sensor and cause false readings.
