Your oven is showing an F2 error code and refusing to heat up, which typically means the temperature sensor or control board has detected an overheating condition. This safety feature prevents potential fire hazards, but it also means you can’t use your oven until the issue is resolved.
Step-by-Step Fixes
Step 1: Power cycle your oven (2 minutes)
Turn off your oven completely and unplug it from the wall outlet. If you can’t reach the plug, flip the circuit breaker for your kitchen. Wait 60 seconds before restoring power. This simple reset clears temporary glitches in about 30% of F2 error cases.
Step 2: Let the oven cool completely (30-45 minutes)
If your oven was recently in use or running a self-clean cycle, the F2 code might appear because internal temperatures exceeded safe limits. Open the oven door and let it cool down completely. Once cooled, try turning it on again at a low temperature like 200°F to test if the error returns.
Step 3: Check and clean the temperature sensor (15 minutes)
Look inside your oven for a thin metal probe sticking out from the back wall – that’s your temperature sensor. Make sure it’s not touching the oven walls or racks. Gently pull it forward about half an inch if needed. Clean any food debris or grease buildup around the sensor using a damp cloth. Never use harsh chemicals or abrasives on this delicate component.
Step 4: Inspect the door seal (5 minutes)
Run your hand along the rubber gasket surrounding your oven door. Feel for tears, gaps, or areas where the seal has come loose. A damaged door seal lets heat escape, causing the oven to overcompensate and trigger the F2 error. Small gaps can be temporarily fixed with high-temperature silicone sealant, ideal for quick repairs when you need your oven working immediately.
Step 5: Test the temperature sensor resistance (20 minutes)
This step requires a multimeter and is best used in situations where previous steps haven’t worked. Disconnect power to your oven first. Remove the temperature sensor by unscrewing it from inside the oven. Set your multimeter to measure resistance (ohms). At room temperature (around 70°F), the sensor should read approximately 1,080 ohms. Significantly different readings indicate a faulty sensor that needs replacement.
Likely Causes
Cause #1: Faulty temperature sensor
The temperature sensor monitors your oven’s internal heat and sends this data to the control board. When this sensor fails or gives incorrect readings, your oven’s computer thinks it’s dangerously hot and displays the F2 error. You can identify this issue when the error appears immediately after turning on the oven, even when it’s completely cold. The solution involves replacing the sensor, which costs between $20-50 and takes about 30 minutes to install.
Cause #2: Control board malfunction
Your oven’s electronic control board acts like the brain of the appliance, processing all inputs and controlling heating elements. Control board failures often happen after power surges or in ovens manufactured between 2015-2020, which had higher failure rates. Signs include random error codes, unresponsive buttons, or the F2 code appearing even with a new temperature sensor installed. Control board replacement typically costs $150-300 and is not recommended when your oven is over 10 years old.
Cause #3: Stuck relay contacts
Inside your control board, small electrical switches called relays turn the heating elements on and off. Sometimes these relays get stuck in the “on” position, causing continuous heating that triggers the F2 safety error. You might notice your oven getting extremely hot very quickly or heating elements glowing even when the oven is supposedly off. This problem requires professional control board repair or replacement.
When to Call Expert Help
Contact a professional appliance technician when the F2 error returns after trying all basic troubleshooting steps, or if you smell burning plastic or see visible damage to wiring. Professional help is essential when dealing with gas ovens showing F2 errors, as gas appliances require certified technicians for safety reasons.
Most reputable repair services in 2025 offer video consultations where you can show them the error code and get immediate guidance. Expect to pay $75-150 for a diagnostic visit, though many companies waive this fee if you proceed with repairs. If your oven is under warranty or less than 5 years old, contact the manufacturer first as F2 errors often qualify for covered repairs.

“My [oven brand and model] displays error code F2 and won’t heat. I’ve already tried [list what you’ve done]. The oven is [age] years old and was working fine until [when problem started]. Should I attempt to replace the temperature sensor myself or call for service? What other troubleshooting steps are specific to my oven model?”
Remember that F2 error codes are safety features designed to protect your home. While frustrating when you’re trying to cook dinner, these errors prevent potentially dangerous overheating situations. Most F2 errors can be resolved with basic troubleshooting or affordable sensor replacements, making this a manageable problem for most homeowners to tackle.
