Maytag oven needs temp calibration

I have an electric maytag oven (CRE8700ADE) and the temperature is way off. I did a test where I set the oven to 350 degrees for 30 minutes and the oven thermometer I had placed inside read only 290 degrees!

I am looking for information on how to correct this. Can it be calibrated easily?

Take your temp knob off and look in the center of the stem and you should find a small set screw. Using a small precision screwdriver, turn the screw until you see the light come on. (You won't have to turn it far.) Turn it a little at a time, maybe a 1/16 of a turn. Leave your thermometer in the oven with the door closed and at or near the temp probe that is in the oven. This way, you are getting a true reading.

I have a Jenn Air JJW9830DDP double oven electric, and the temperature in the oven is about 100' less than what it reads on the display. I tested the temp sensor and it ready 1073 ohms. Any s


Well, your temp sensors can still be bad. If not, there's always a new control board you buy!

However, I wouldn't drink water from that oasis without making ABSOLUTELY sure I'm not seeing a mirage.

The only common denominators between your upper and lower oven temp readings is the firmware and the oven thermometer you are using to visually check the temps.
What type of thermometer are you using to check your oven temperatures with?
If it's not a digital thermometer used specifically for testing ovens, you might just be leading leading yourself astray.
You need a calibrated thermometer. If I don't have a calibrated digital thermometer on me, I use two or three oven thermometers (the dial type) and average the readings.
It's the only way to be as close as possible with a digital probe.

If you have thoroughly verified that your oven is in fact not reading the correct temperature, then you can adjust it +/- 35 degrees F via your oven's control panel.
To adjust the oven temperature:
1 - Press Setup pad.
2 - Select the down arrow to scroll to the next screen.
3 - Select Temp Adjust using the Quickset pads.
4 - Select upper or lower oven (select models).
-"Set temperature offset using the Upper Set Knob" is displayed.
5 - Enter the desired temperature change using the Set knob.
The temperature can be increased or decreased up to 35 degrees.
The temp. change is displayed at the top of the window.
6 - Press the Set knob to accept the change.

Now, if you are still worried about the temp. reading being off, replace both the upper and lower temp sensors. That's all you can do besides replace the main board.

My Maytag MGR5750ADW oven will take forever to preheat. It does get hot, but the preheat light takes a very long time to go out. Food takes much longer to cook as the oven does not seem to get up to temp.


Hello there and welcome to fixya
When the food you're baking is done on top but not on the bottom--or when baking just takes far too long to finish--the bake element may be burned out. You may get fooled into thinking it's working, because the oven is hot inside. But many electric ovens use the broil element, too, during the preheat and bake cycles. So the food may be getting heated only by the broil element, which causes poor baking results. If the bake element is burned out, replacing it should solve the problem. To determine if the heating element is burned out, watch the part testing video at the bottom of this page. Otherwise, you need to further troubleshoot the oven's electrical system to locate the defective wire or component. When the temperature is consistent but too high or too low, it could be one of several different things. First check to see if the thermostat sensing bulb has come loose from its holder. It could be lying on the floor of the oven or resting on the heating element. This would cause the oven to not heat correctly. If the thermostat bulb is not dislodged, it's likely that the thermostat or sensor is either mis-calibrated or defective. Electronic ovens with a digital display use a sensor to monitor oven temperature. To solve temperature problems for these models, you may need to replace the sensor. On some digital-display models, you can calibrate the temperature using the key pad. See your operator's manual for details. Ovens without a digital display often use a mechanical system for controlling temperature. On many of these units, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat. If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.

My oven will not warm up. It will just stay at 100 degrees. The gas stove works fine but the oven will not warm up to the desired heat. It worked fine 2 days ago, any suggestions.


My dear friend, i suspect the oven thermostat to be responsible for this. It is a switch that opens when the temperature of a oven is set. Therefore it is bad and cannot work according to the temperature it is set to. The thermostat is located at the control panel where a liquid filled temperature sensor bulb which senses and maintains the temperature of the oven by turning it on and off at every cycle.
First You have to test the thermostat before replacing it. Before repairs or testing can begin you must disconnect the electricity at the fuse panel, at the circuit breaker panel, or by pulling the plug. Make sure the power is off before proceeding. A jolt from 220 volts can be fatal, use caution! Since i do not know the exact maytag oven type, here is the general process for all types of oven.
  1. Access the oven thermostat, which is located in different places depending on the make and model: On freestanding ranges, access the thermostat by removing the screws that hold the back panel in place at both ends. On models with front-loading controls, remove the panel and tilt it for access. Be careful not to let the wires disconnect from their components. Some built-in models have a removable back splash. Lift the backsplash, rest it on the cook top and remove the screws from the back splash, which holds the rear panel. On wall ovens or eye-level ranges, access the control panel by opening the door and removing the screws that secure it. The screws may be under the exhaust hood or below the control panel. If the control panel is hinged, simply tilt it towards you. On some models both the rear and front control panels must be removed. The screws may be found on the trim and occasionally the trim must be removed.
  2. When testing the thermostat switch contacts for continuity, refer to the wiring diagram and remove only those wires being tested - and only one pair at a time. Test switch contact terminals as per your wiring diagram. If the switch lacks continuity at any of the contact terminal points then the entire thermostat switch needs to be replaced.
  3. Adjusting the thermostat: Test the oven temperature by placing the tester in the oven's center and leaving it for 30 minutes at 350 degrees. Record the minimum and maximum temperatures of three cycles, then add those figures together, divide the result by six and you have the oven's average temperature. If the average temperature is more than 25 degrees off, try calibrating the thermostat by following your appliance manual instructions for thermostat calibration.
  4. Normally, thermostats are calibrated by pulling the oven's thermostat knob off, turning the knob over and adjusting the calibration ring on the back. If your oven doesn't have a calibration ring you may need to replace the thermostat.
To replace the thermostat of the oven, please follow the steps below:
  1. Disconnect the capillary tube and push it through the back oven wall, being careful not to break the flammable capillary tube wire.
  2. Remove the screws that secure the thermostat to the control panel and gently pull the thermostat out, leaving the wires in place.
  3. To install a new thermostat, reverse the disassembly procedures, transferring the wires individually from the old unit to the new.
Hope this helped you. Thank you for using fixya.

You will need to have the thermostat looked at or replaced, it may be defective and not reading the correct temp, also try using a manual oven thermometer to check the actual temp in the oven to give you a better idea of what the actual temp is inside

OVEN WILL NOT COME UP TO TEMPERATURE


Hello,

You can calibrate the oven on this model. Press the bake button, adjust the bake temperature up to 550 degrees and then press and hold the bake button until a 0 displays. Now you can adjust the oven temperature up or down to match the display.

Here is a repair manual link that you can use to download frigidaire repair manuals. The one for 30 inch freestanding ranges will have the section on calibrating the oven's electronic control.

Thanks

Could be a couple things. If your machine is actually failing either a control board or an oven sensor.

Also measuring the temperature can only be done by a tech unless you have a special tool. Oven thermometers are inaccurate. Plus most ranges should vary temp between 50-75 degrees unless has a feature or the more recent ones keep it between 15-25 degrees.

Try the biscuit test, buy some biscuit, brand not important, i just say pillsbury. Cook exactly as recommended on package. If results are a little overcooked or a bit undercook try a feature called Adjusting the oven temperature or Calibrating the oven. This can be done by following the instructions in your book.
