How To Calibrate Tappan Oven Temperature
Below, we have listed the steps you need to follow in order to calibrate your Tappan oven temperature…
Step 1: First, you will need to determine how much the oven needs to be adjusted by. Open the oven door and place a thermometer on the center rack.
Step 2: Shut the door.
Step 3: Set the oven to bake at 350 degrees F.
Step 4: After about 25 minutes, look at the reading on the thermometer. If the temperature is off by up to 10 degrees, you should calibrate the oven accordingly.
Step 5: Turn off the bake function.
Step 6: Hold down the “Bake” button for a few seconds or till the oven enters temperature calibration mode.
Step 7: Using the arrows, enter how much you want to add or deduct from the oven’s current temperature.
Step 8: Once you have entered your desired temperature, press the “Start” button to save your selection.
Note that if your Tappan oven temperature is off by over 30 degrees, it cannot be calibrated. An oven that is off by over 30 degrees indicates a faulty temperature sensor or thermostat (depending on which one your oven uses). Read the section below to replace the thermostat or temperature sensor in your Tappan oven.

Tappan Oven Temperature Not Accurate — How To Fix
Below, we have listed the possible reasons why your Tappan oven temperature is not accurate and what to do about them.
1. Temperature Sensor
The sensor monitors the oven’s temperature during the bake and broil cycle. If this component fails, it could cause the oven to heat to the wrong temperature. Below, we have listed the steps you need to follow in order to replace your Tappan oven temperature sensor…
Step 1: Disconnect the power to the oven by unplugging the power cord from the outlet or switching the circuit breaker off.
Step 2: Pull the oven away from the wall and go to the rear.
Step 3: Get a Philips head screwdriver.
Step 4: Using the Philips head screwdriver, take out the screws which hold the oven’s lower rear access panel in place.
Step 5: Lift the access panel off and set it aside.
Step 6: The temperature sensor is on the left side of the oven. Disconnect the wire plug from the sensor.
Step 7: Take out the two screws which hold the sensor to the oven’s rear.
Step 8: Pull the sensor out of the oven.
Step 9: Get a new Tappan oven temperature sensor.
Step 10: Push the new sensor into place.
Step 11: Secure the sensor to the oven using the two screws.
Step 12: Reconnect the wire plug to the new temperature sensor.
Step 13: Reposition the oven’s lower rear access panel.
Step 14: Hold the panel in place with the screws.
Step 15: Reconnect the power to the oven by switching the circuit breaker on or plugging the power cord back in.
Step 16: Push the oven back to the wall.

2. Thermostat
A thermostat is used in some Tappan ovens to monitor the temperature. If your Tappan oven temperature is not accurate but it doesn’t use a temperature sensor, the thermostat is most likely faulty. Below, we have listed the steps you need to follow in order to replace the thermostat in a Tappan oven…
Step 1: First, disconnect the oven’s power to avoid the risk of electrocution. Do this by switching off the oven’s circuit breaker.

Step 7: Lift the door off the oven and set it aside on a sturdy cloth lined surface.
Step 8: Slide out the racks in the oven and set them aside.
Step 9: The thermostat’s capillary tube is on the upper back wall of the oven’s interior. Lift the capillary tube off the clips.
Step 10: Go to the oven’s rear.
Step 11: Using a Philips head screwdriver, take out the screws which hold the oven’s rear panel in place.
Step 12: Set the panel aside and take out the screws which hold the oven’s top panel in place.
Step 13: Set the top panel aside.
Step 14: Pull off the oven’s control knob.
Step 15: Now, take out the two screws which hold the thermostat to the oven.
Step 16: Lift the thermostat off the oven. If the thermostat is attached to a selector switch, pull it off.
Step 17: Note where each wire goes on the thermostat by taking a picture.
Step 18: Now, disconnect the wires from the thermostat using a pair of needle nose pliers.
Step 19: Pass the capillary tube out through the hole in the top of the oven.
Step 20: Fully remove the thermostat.
Step 21: Get a new thermostat for your Tappan oven.
Step 22: Insert the capillary tube through the hole in the oven.
Step 23: Position the thermostat on the selector switch and push it into place.
Step 24: Connect the wires to the new thermostat making sure that each one goes to the right place.
Step 25: Secure the thermostat to the oven using the two Philips head screws.
Step 26: Push the oven’s control knob back into place.
Step 27: Return the oven’s top panel and secure with the screws.
Step 28: Reposition the rear panel as well and hold it in place with the screws.

3. Bake Element
If the temperature sensor isn’t faulty, you should check the bake element next. The bake element is one of the main heating components in an electric oven. If the bake element starts to fail, it could cause to oven to heat up to the wrong temperature. Read this article: Tappan Oven Element [Issues & Proven Solutions] to learn how to replace the bake element in your Tappan oven.
4. Control Board
If the bake element, thermostat, and sensor aren’t faulty, the control board may be faulty. If the board fails, it could cause the oven to heat up to an incorrect temperature. Since it is difficult to test the control board, make sure to check the bake element, sensor, and thermostat before replacing the board. Read the “Tappan Oven Element” article in the section above to replace the control board in your Tappan oven.
