Troubleshooting your Tappan gas wall oven when it won't broil

A failed relay on the electronic oven control board could prevent the broiler from heating. Disconnect electrical power from the oven and check the electronic control board. Replace the electronic control board if you see a burnt spot or melted relay. Some wall ovens have a relay control board that's separate from electronic control board. The relay control board has the electrical relay that controls voltage going to the broiler element or broiler burner. Examine the relay control board and replace it if you see a burnt spot or melted relay.

Gas wall ovens often use a glow-bar igniter and a safety gas valve to control the broiler burner. Those components are connected in a series-type electrical circuit. When the glow-bar oven igniter is hot enough to safely ignite the gas, the safety gas valve opens. Replace the broiler igniter if doesn't glow when activated, or if it glows but doesn't get hot enough to open the safety gas valve.

How to replace the temperature sensor in your Tappan gas wall oven

• Shut off all electricity to the gas wall oven. Turn the gas shut-off valve to the off position. Wear work gloves to protect your hands during the repair.
• Find the temperature sensor probe in the top left corner of the back wall of the oven interior. Using a 1/4-inch nut driver, remove the 2 hex head screws from the base of the temperature sensor probe.
• Carefully pull the oven temperature sensor probe forward into the oven interior. The wires connected to the probe have enough slack that you can pull it a just few inches—far enough to disconnect the wires. As you pull, use needle-nose pliers to guide the wire harness connector through the hole in the oven wall. Pull the temperature sensor probe a few inches forward so you can reach the wire connector.
• Holding the connector with needle-nose pliers, depress the locking tab on the plug and disconnect the plug from the sensor probe. Don't let the connector slip back through the hole, or you must remove the back panel of the oven to retrieve it.
• While holding the connector with a pair of needle-nose pliers, snap it into the plug of the new probe. Push the wire into back wall of the oven. Position the new sensor probe and line up the holes for the mounting screws. Insert the mounting screws and tighten firmly using a nut driver.
• Turn on the electricity and the gas.
