The oven heat will not regulate. At 450 degrees cooking thermometer is around 200 degrees. At 550 degrees the cooking thermometer reads over 600 degrees. I have replaced the temp sensor (thermocouple), no help. Inspected the control panel, can't see any obvious defects. At this point I am guessing it is a problem with the control panel. Are there any adjustments or other parts that could be the problem?

have you checked with an oven type thermometer for 350 degrees against the setting of 350 degrees,if its off very far then its the oven temp sensor in the upper left middle or right rear wall of the oven thats bad it looks like a small pencil type rod 2" to*' long it merely unplugs off the oven s control panel in the rear,you can test its resistance also to get an idea if it is your culprit,otherwise the oven element could have a hot spot in it and not letting all the current thru to properly heat the element,it will be dis-colored in that area
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.
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.
If you are monitoring the oven temperature with an analog style thermometer you may actually be ok, but seeing the thermometers slow reaction time.
Some newer ovens actually do pre-heat beep prior to reaching temp in an effort to conserve eelectricity.
A good home test is to try your oven at several different temps to see if there is any variation in internal temperature. Try it one day on 300, the next at 375 and another day at 450. Give your analog style thermometer time to catch up (usually just about 15 min) and leave it on for a half an hour to see if the temp maintains.
Also Beware of aluminum foil AND THE NEW OVEN LINER MATS as they can alter oven performance bay absorbing and blocking the ovens natural heat radiation and convection air flow currents that happen in all ovens, not just convection models.
Another interesting fact is that older ovens used a thermostat in them that operated much like your thermometer and was very slow to react making the oven typically about 100 degrees hotter than where the customer set it. This was just a fact of life before the advent of electronic temperature management and became noticeable when people began trying to bake older "hand me down" recipes in the newer ovens with less than stellar results.
You can mimic the older oven performance by preheating the oven about a hundred degrees higher than called for and after it reaches temp, re-set it to the correct temperature and put the items in right away.
If you find your temperatures fluctuating ask your servicer to replace first the temp sensor and as a last resort the control board as this part is usually pretty expensive.
Good Luck with this!
This sounds like a weak igniter, it would have to be a gas oven and the symtoms usually are: takes longer than normal to ignite the burner, may or may not smell gas in the oven, does not maintain set temperature, eventually won't heat at all. On gas ovens, a glo igniter is like a light bulb, the more you cook, the faster it wears out. Bottom line, needs to be replaced. Good luck.
I recommend you buy a cheap oven thermometer and check the oven temperature yourself. As a gasfitter I know temperature conversions (numbers to degrees) are approximate and I think may be done on purpose so consumers won't complain if they put a thermometer int he oven and it differs from the thermostat. Check the temperature in the centre of the oven. do not use pans and trays that fill the sheld as gas ovens need room to circulate the hot air. Also do not place items in the oven so the top of it is near the top of the oven - otherwise it will burn. I have found when cooking a chicken it needs to be turned otherwist the bottom of it may not be cooked.
Set the oven thermostat to 100 degrees ( very low heat) and wait to see if the onen indicator goes off. If it doesn't then the oven thermostat may be faulty. If you have an oven thermometer, then use that to check the oven temperature.
The Taylor oven thermometer you bought is decent at best. It is most likely the sensor inside the oven. Has your clock displayed any fault codes? F, followed by a number? Changing the sensor will probably correct the problem.
you might have already thought of this, buy an oven thermometer you can pop in the oven.
I bought one from my local cook shop
I have a the same cooker and similar problem - mine gets hotter by 50 degrees so I set the temperature 50 degrees lower than needed.
I noticed the problem a few years a go and luckily hasn't got any worse.
