These are not very accurate but your reading are out of spec. definitely
check probe and also leave it for some time and then check measurement (5 min or so) maybe it needs longer top stabilize
temperature (K type) uses mV for calculation and therefore cannot be adjusted without adjusting mV DC setting also (if that is possible on this meter)

How to calibrate kenmore meat probe? it says 170degrees when plugged in cool.

170 degrees is likely the minimum it can read. put a container of water in the oven, put the probe in the water, and set the oven for 250 degrees. Watch the probe, and see what temperature it shows when the water boils. Depending on your altitude, it should be 212 or a little less.

We have a 2-year old Viking gas range (model VGCC5304BCC) and lately the oven temperature has beeen running about 25-40 degrees higher than the selected temperature. I cannot find a way to calibrate or...

use a digital thermometer with a probe inside the cavity, normal preheat is 30 mins to 350, wait until the 3rd cycle to see what temps are in the cycle, record high , low temps add and divide. plus or minus 10 are in scope. ex 350 on at 340 off at 360 will avg 350. depending on the serial and age, there is no calibration unless your Electronic thermostat would be suspect. Hope this helps.

Blomberg BEP 906. After power went out a couple

Hello.

When baking or cooking common foods in your oven, it is important that the oven heats to the proper temperature. Otherwise, the food in your oven could become over- or undercooked. The electric ovens are able to be calibrated if only slightly off, however, if the temperature is 25 degrees off or more, you should replace the oven sensor. The oven sensor is the device in the oven the detects the temperature. The control board increases or decreases the oven temperature, depending on the oven sensor reading. Before calling a repair technician, attempt to calibrate your oven or change the oven sensor.

Instruction

1 Turn on the oven and set the temperature to a medium-heat setting, such as 350 degrees.

2 Allow the oven to preheat and then open the door and insert the oven thermometer.

3 Allow the oven thermometer to remain in the oven for a few minutes and the look at the temperature reading, comparing it to the oven temperature setting.

4 Recalibrate the oven if the temperature is only slightly off, or replace the oven sensor if the temperature is greatly off, such as 25 degrees or more.

Calibrating the Oven

1 Turn off the oven to prior to calibrating.
2 Press and hold the "Bake" button until the calibration settings are displayed on the display.

3 Use the arrow buttons or "+" and "-" buttons to adjust the temperature the number of degrees that the oven is out of calibration.

4 Press the "Start" button to save the calibration settings.

Replacing the Oven Sensor

1 Unplug the oven from the wall or cut the power to the oven in your breaker panel.

2 Open the oven door and remove the oven racks.

3 Locate the oven sensor, located at the top-center of the rear oven wall.

4 Remove the mounting screw securing the oven sensor to the wall and then pull the oven sensor away from the wall.

5 Remove the cable connected to the terminal on the rear of the oven sensor and then discard the oven sensor.

6 Connect the cable to the terminal on the new oven sensor and then reposition the oven sensor and secure it using the mounting screw.

7 Replace the oven racks and then restore power to the oven.

Thanks.

Current temperature on Taylor TruTemp 3528 reads "LLL"

It needs calibrated. LLL (low) means you need to put the probe in a glass of ice water. It will then say HHH (high) means you need to put the probe in boiling water, don't let the probe touch the sides of the metal pot of boiling water.

My Super capacity 465 is not cooking at the right temp. It is about 25 degrees off. is it a thermalstat?

most likely yes... there is a thermostat probe that probley needs to be replaced... however 25 degrees is not to far out... some of these units you can get into the control settings and calibrate... if nobody else has ever worked on unit normally there is some literature in the control area behind the panel that is for the servicer and it should tell you how to get into setup and adjust/calibrate the temperature and offsetr it by 25 degrees... you are just reprogramming unit... if that doesn't help then get a new thermostat... good luck to you ....

Kitchen Aid oven does not get up to temp.

you can only calibrate the oven + or - 35 degrees. if you are over 35 degrees off you will need to ohm your temperature probe to see if you get about 1280 ohms if you do then you need to replace the clock control. if you ohm the temperature probe and you are off by more than 10% then you will need to replace the probe. in most cases both the control and probe would need to be replaced.

Digital oven temperate is wrong

Yes, that is the probe that sends info to the controller.

If it's not bad, then the controller is, but normally it's the probe.

Check that the controller has not been incorrectly calibrated before you change the probe out, although most do not allow a swing of more than 15-20 degrees. Yours may allow more though.

I am guessing you measured the actual temperature, to the set point temperature, with a know good thermometer.

Oven heats to 200 and indicator dings

Try to set it at 500 degrees and see if it goes off at 350. If it does, then it probably needs calibrating. You can calibrate it by taking the knob off and finding a set screw in the stem where the knob sits. If this is not the problem, you may have to replace the thermostat. By the way, check to see if your temperature probe is not touching the wall of the oven. It will give it a false reading. Let me know if any of these things work and we will go from there.
