Tappan Oven not heating

Is your Tappan oven not heating? The range/stove/oven igniter is the most likely cause. A weak igniter may glow for more than 90 seconds without lighting the gas, while a failed igniter will not glow or will lack continuity when tested with a multimeter. If the igniter checks out, inspect the bake element for holes, blisters, or a failure to glow red, then test it for continuity. A defective oven control board can also prevent voltage from reaching the bake element, broil element, or igniter. Next, test the temperature sensor for the correct resistance at a set temperature, since a faulty sensor can cause a Tappan oven not heating problem. A damaged bake or broil spark electrode may not ignite the gas burner, so check for cracks in the porcelain or a worn electrode tip. Finally, inspect and test the broil element for visible damage and continuity. Disconnect power before testing or replacing parts, and shut off the gas supply when working on gas components. Enter your Tappan range, stove, or oven model number to find the exact replacement part for your appliance.

01 - Tappan Range/Stove/Oven Igniter

The igniter is the most commonly defective part for an oven not heating. The igniter has two main functions. First, the igniter draws electrical current through the oven safety valve to open it. Second, the igniter gets hot enough to glow and ignite the gas in the oven burner. If the igniter gets weak, it will fail to open the safety valve correctly. If the valve does not open, the oven will not heat. To determine if the igniter is defective, observe the igniter when the oven is on. If the igniter glows for more than 90 seconds without igniting the gas flame, this indicates that the igniter is too weak to open the valve. I...f the igniter is weak, replace it. If the igniter does not glow at all, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it.

02 - Tappan Range/Stove/Oven Bake Element

When the bake element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the heating element has burned out, it will be visibly damaged. Inspect the heating element for holes or blisters. To determine if the bake element has burned out, use a multimeter to test the element for continuity. If the bake element does not have continuity, replace it.

03 - Tappan Range/Stove/Oven Control Board

An oven's control board will often be used to send voltage to the bake and broil elements or the igniters. If the control board is defective, the voltage may not be sent to these components and the oven will not heat. You can inspect the board for signs of damage or a shorted component. You can also use a multimeter to test for voltage reaching the bake or broil elements or igniters after reviewing the appliance's wiring diagram.

04 - Tappan Range/Stove/Oven Temperature Sensor

An oven's temperature sensor monitors the temperature inside the oven cavity in order to maintain an accurate temperature. If the temperature sensor is faulty, the oven may not heat at all. The sensor can be tested for a proper ohm reading at a set temperature with a multimeter to help determine if the part is defective or not.

05 - Tappan Range/Stove/Oven Bake or Broil Spark Electrode

For bake & broil burner ignition an oven burner spark electrode is used to ignite the gas. The electrode is a device that sits right next to the burner. It functions like a spark plug. As power is applied to it a spark jumps from the spark electrode tip to the to the electrode shield, igniting the gas. If the electrode is broken or worn out the spark may not occur. Visually inspect the electrode assembly for cracks in the porcelain housing or damage to the electrode tip itself. Be aware that a proper ground and the correct polarity of the incoming voltage to the range is necessary for the electrode control to sense the p...resence of a flame once the burner is ignited. If the burner goes off after ignition check for proper ground and the correct polarity at the wall outlet.

06 - Tappan Range/Stove/Oven Broil Element

Inspect the broil element for holes or blisters. When the broil element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the broil element has burned out, it will be visibly damaged. To determine if the broil element has burned out, use a multimeter to test the element for continuity. If the broil element does not have continuity, replace it.
