Gas Oven Won’t Turn Off — Gas Range Troubleshooting

Introduction

This tutorial provides a step-by-step guide for troubleshooting a gas oven that won't turn off. Understanding the common issues and parts involved can help you effectively diagnose and resolve the problem, ensuring your oven operates safely and efficiently.

Step 1: Identify the Symptoms

• Check if the oven is still heating: If the oven remains hot after the timer has expired, this indicates a malfunction.
• Listen for sounds: If you hear the gas flow or the igniter clicking, the oven may not be shutting off properly.

Step 2: Inspect the Temperature Sensor

• Location: The temperature sensor is usually located inside the oven cavity.
• Testing: Use a multimeter to check the sensor's resistance. The typical resistance should be around 1100 ohms at room temperature. If it’s outside this range, it may need replacement.
• Common Pitfall: Ensure the oven is unplugged before performing any tests to avoid electric shock.

Step 3: Examine the Relay Board

• Function: The relay board controls the power to the oven and can malfunction, causing the oven not to turn off.
• Visual Inspection: Look for any burnt or damaged components on the relay board.
• Testing: If you have a multimeter, check for continuity across the relay contacts. A lack of continuity may indicate a faulty relay.

Step 4: Check the Control Board

• Signs of Damage: Look for physical damage such as burnt traces or components on the control board.
• Reset the Control Board: Sometimes, simply resetting the control board by unplugging the oven for a few minutes can resolve issues.
• Replacement: If the control board is defective, it may need to be replaced. Ensure you get the correct part for your oven model.
