The issue you're experiencing with your Frigidaire Oven's clock resetting to a blinking 12:00 when you push any of the 4 top burner knobs is likely related to an electrical problem or a glitch in the oven's control system. While I can't diagnose the exact cause without inspecting the appliance, there are a few potential reasons for this behavior:
Power surge: If there's a sudden surge in electrical power, it can temporarily disrupt the oven's control panel, causing the clock to reset. Power surges can occur due to various reasons, such as lightning strikes or fluctuations in the power grid.
Loose connections: Loose electrical connections within the oven's control panel can result in intermittent power loss to the clock and cause it to reset when you interact with the burner knobs. Vibrations from pushing the knobs might be affecting these connections.
Control board malfunction: The oven's control board or electronic control module may be faulty, causing intermittent issues with the clock display when the burner knobs are operated.
Capacitor discharge: Some ovens use capacitors to retain power and settings during brief power outages. If the capacitors are malfunctioning, it may lead to the clock resetting randomly.
Electromagnetic interference: In rare cases, nearby electromagnetic interference from other electronic devices or appliances might interfere with the oven's control panel, causing the clock to reset.
To resolve the issue, you can try the following steps:
Check the power supply: Ensure the oven is properly connected to a stable power source. Consider using a surge protector to protect the appliance from power fluctuations.
Tighten connections: If you have the necessary skills and knowledge, you can try opening up the oven's control panel (make sure the power is off) and check for any loose wires or connections. Reconnecting them securely may help.
Reset the oven: Sometimes, a simple reset can resolve glitches. Turn off the oven at the circuit breaker for a few minutes and then turn it back on to see if the issue persists.
Contact Frigidaire or a professional technician: If the problem persists or if you are not comfortable performing any troubleshooting yourself, it's best to contact Frigidaire customer support or a certified technician who can diagnose and fix the issue safely.
Remember, troubleshooting electrical appliances can be dangerous, and it's essential to prioritize safety. If you're unsure about any step or feel uncomfortable with the process, it's best to seek professional help.
