Gas Oven Not Heating? Here’s What Might Be Wrong – and How Matt’s Appliance Care Can Help

If your gas oven won’t heat, you’re likely dealing with a frustrating dinner delay — or worse, a holiday cooking disaster. But don’t worry, Matt’s Appliance Care is here to help.  Whether your gas oven won’t ignite at all or it's just not getting hot enough, here’s what you need to know.

Common Reasons Your Gas Oven Isn’t Heating Properly

If your gas oven isn’t heating, the issue usually falls into one of a few key categories. Here’s a breakdown of the most common causes:

1. Faulty Igniter

The igniter is the most common cause of a gas oven that won’t heat. Over time, igniters wear out and can’t draw enough current to open the gas valve.

🔧 Signs of a bad igniter:

• Oven clicks but doesn’t ignite
• You hear a buzz or hum, but no flame
• Burner glows but no heat builds

Fix: Matt’s Appliance Care can test and replace the igniter safely.

2. Defective Gas Valve

If the safety valve doesn’t open when it should, gas won’t flow into the burner. This can happen if the valve itself is faulty or if the igniter isn’t triggering it properly.

Important: Gas valves are not DIY-friendly. Call a tech to handle this repair safely.

3. Thermostat or Temperature Sensor Malfunction

If your oven turns on but doesn’t reach the desired temperature (or heats unevenly), the oven thermostat or temperature sensor might be to blame.

Fix: I will test the sensor’s resistance and recalibrate or replace it if needed.

4. Control Board Failure

In newer gas ovens, a faulty control board may not send the correct signals to ignite the igniter or maintain temperature.

Warning Signs:

• Display shows error codes
• Oven starts but cuts off randomly
• No response from controls
