How to Reset Oven After Power Outage

After a power outage, your oven may display error codes, show a flashing clock, refuse to operate, or behave erratically. Here's exactly what to do to reset your oven and get it working normally again.

Step 1: Check the Circuit Breaker

Power outages and power surges can trip circuit breakers. Before anything else:

1. Go to your home's electrical panel
2. Find the breaker labelled for the oven or kitchen range (usually a double-pole 40–50 amp breaker)
3. If it's in the middle position (tripped), switch it fully OFF then back ON
4. If it trips again immediately, there may be a wiring fault — call an electrician

Step 2: Perform a Hard Reset

Even if the breaker hasn't tripped, a power outage can leave the oven's control board in an error state. A hard reset clears this:

1. Switch off the oven's circuit breaker (or unplug if accessible)
2. Wait 5 minutes — this allows capacitors in the control board to fully discharge
3. Restore power
4. The oven should restart normally

Step 3: Reset the Clock

After a power outage, the oven clock will typically flash "12:00" or show dashes. Most ovens won't operate in timed cook or delay start modes until the clock is set:

• Press the "Clock" button
• Enter the current time using the number pad or up/down arrows
• Press "Start" or "Clock" again to confirm

The exact method varies by brand — check your oven manual if the above doesn't work.

Step 4: Clear Error Codes

If the display shows an error code (F1, F2, E1, etc.) after power is restored:

1. Press "Cancel" or "Clear/Off" to attempt to clear the code
2. If the code clears and the oven operates normally, the outage caused a temporary fault that has resolved
3. If the code returns immediately, there may be a genuine component fault — see our guide on oven error codes

Step 5: Test All Functions

After resetting, test the oven's main functions:

• Set to bake at 180°C (350°F) and confirm it heats
• Check the oven light works
• Check the fan runs (fan ovens)
• Test the grill/broil function briefly

Brand-Specific Reset Methods

GE Ovens

Press "Clear/Off" for 3 seconds. If unresponsive, trip the circuit breaker for 30 seconds then restore.

Whirlpool / KitchenAid

Press "Cancel" twice. If still showing an error, disconnect power for 5 minutes.

Samsung

Press and hold "Start/Set" for 3 seconds, or disconnect power for 5 minutes.

LG

Press "Clear/Off" then disconnect power for 5 minutes if the error persists.

If the Oven Still Won't Work After Resetting

Power surges during outages can damage oven components, particularly the control board. If the oven remains unresponsive after a full reset:

• Test for voltage at the oven with a multimeter. The AstroAI Digital Multimeter 2000 Counts measures AC voltage — confirm the outlet or hardwired connection is supplying correct voltage
• If voltage is correct but the oven doesn't respond, the control board may have been damaged by the surge
• Consider having the oven inspected by a professional engineer

Protect Against Future Power Surges

Power surges are a leading cause of control board failure in modern ovens. A whole-home surge protector installed at the electrical panel provides the best protection for all appliances simultaneously.

Summary

After a power outage: check and reset the circuit breaker, perform a hard reset by cutting power for 5 minutes, reset the clock, and clear any error codes. Test all functions before cooking. If the oven remains unresponsive, the control board may have been damaged by a power surge.
