Message panel keeps flashing F10 error

The error message "5h:0" on a Teka HL890 oven indicates that the oven is in demo mode. Demo mode is a setting that is used by retailers to show off the oven's features without actually cooking anything. To turn off demo mode, follow these steps: Press and hold the "+" and "-" buttons on the oven's control panel for 10 seconds. The error message will disappear and the oven will be in normal mode. If the oven still does not heat up after turning off demo mode, there may be a problem with the heating element or the temperature sensor. In this case, it is best to contact a qualified technician for assistance. Here are some other possible reasons why your Teka HL890 oven might not be heating up: The oven is not plugged in. Make sure that the oven is plugged into an outlet that is working properly. The oven door is not closed properly. Make sure that the oven door is closed all the way. The oven thermostat is set too low. Make sure that the oven thermostat is set to a high enough temperature. There is a problem with the heating element. The heating element may be broken or it may not be getting enough power. There is a problem with the temperature sensor. The temperature sensor may be broken or it may not be reading the temperature correctly.

A faulty RTD sensor probe is one of the causes for an F10 code or overheating oven. The sensor probe is supposed to detect the exact temperature in the Frigidaire electricrange cavity and relay it to the oven's main control so it knows when to shut off the heating elements.
Hope this helps

The F10 error means that the high temperature sensor is reporting a runaway temperature and shut down to avoid a potential fire. Try unplugging the stove or tripping the circuit breaker to reset the code.

If the error recurs, unplug the stove (or turn off the circuit breaker) again. Look at the broiler and bake elements with a flashlight. If it has any damage (breaks, char, melting), you will need to replace the element. Check where the elements connect to the oven and replace them if there is any charring on the back wall.

If the elements are undamaged, you need to check the wiring to identify if the problem is at the elements, the high temperature sensor, wiring or the control board. You will need to access the wiring from the back of the stove. Disconnect the wires to the heating elements. Then disconnect the wiring connections at the high temperature sensor and the control board. Without a model number, I can't be completely sure of the resistance that should be seen at various points. Please post a comment with the model number of the stove and I'll try to confirm the expected and faulty resistance values. Most likely, the resistance should be under 50 ohms but above zero between the left and right contacts of the elements and the violet wires in the wiring harness at the control board. The high temperature sensor should probably have a resistance between 1,000 and 1,200 ohms. If the resistance is high, you'll need to replace the appropriate parts. (Note: if the wiring at the control board gives a reading similar to the resistance of the high temperature sensor, the control board is the likely suspect.)

I hope this helps. If your stove is under warranty, contact Sears/Kenmore to fix the issue. If you aren't comfortable testing the wiring, contact Kenmore for a service call.

The thermostat is defective. It is a temperature sensor operated switch. It turns the heating element on and off to regulate the proper temperature in the oven at all times.

Just went thru this with my GE/Hotpoint oven....the oven temp sensor removed from oven should measure about 2K ohms and vary when put in ice water and hot water...if it does then problem is control panel circuit board.My oven's board was listed at $300+ so I bought new range ($500+).

Your Kenmore oven has a built-in fault detector. When the oven detects an issue, the display screen on the control panel will flash a fault code. The F10 fault code on your Kenmore oven indicates that the thermal protector on your oven's control unit, or microcontroller (MCU), has overheated. If the MCU overheats, the computer stops all motor functions. Several items on your oven could cause the thermal protector to overheat. Therefore, you must troubleshoot the F10 code to determine why it appeared on your display panel. Instructions 1 Inspect the area around and behind the oven to ensure you did not place the oven next to a source of heat, such as a register vent or other appliance that becomes very hot. If this is the case, you must remove the oven from the heat source to prevent the issue from occurring again. 2 Inspect the oven to ensure all vents on the oven are open and unblocked. This includes heat vents that vent to the outside of the home. Remove any clogs from the oven's venting and check to see if the code reappears. 3 Inspect all of the wiring harnesses that connect to the MCU. Remove the back cover from the control panel with a screwdriver. Look for disconnected harnesses or any harnesses with black residue on them. This indicates an issue with the MCU. Remove the bolts that secure the MCU to the control panel housing and then replace the MCU with a new one. Reconnect all of the harnesses and retest.

HI, this control(clock/timer), will need to be replaced at this time. this code represent a control fault within the chip set(logic). this control has failed.

its your temp sensor. replace it and it should fix ur prob
F2=overheat
is your bottom element connected?

sure its possible, sounds like you've blown an over limit thermostat behind stove, gets too hot and for safety reasons cuts off unit untill replaced

please tell about the make & serial no. of oven.
