Oven will not heat; convection fan runs when in convection mode, but elements won't heat for convection bake, pure convection, bake, or broil; it comes on as if it's going to work but the temp gauge never goes above 135 and elements never heat up

Part F161 is the Convection Element. Check it for continuity with a multimeter and also check the connection tags to it as they can melt.

f the oven doesn't heat and the on-off light works, test the appliance controls, motor,
and heating element .

The issue you're experiencing with your Bosch convection microwave not heating in convection mode could be caused by a few different things. Here are a few things to check:

1. Check the settings: Make sure that the microwave is set to convection mode and that the temperature and time settings are correct.
2. Check the element: The bottom heating element is responsible for providing heat during convection mode. Make sure that the element is not damaged or burnt out. You can visually inspect it, if it is damaged it will need to be replaced.
3. Check the fan: The fan is responsible for circulating hot air during convection mode. Make sure that the fan is not blocked or damaged. If it is, it will need to be replaced.
4. Check the control board: The control board is responsible for controlling the functions of the microwave. A malfunctioning control board could prevent the microwave from heating in convection mode.
5. Check for a blown thermal fuse: A thermal fuse is a safety device that cuts off power to the oven if it overheats. If the thermal fuse is blown, it will need to be replaced.
6. Check for a blown thermal cut-off: A thermal cut-off is a device that cuts off power to the oven if it overheats. If the thermal cut-off is blown, it will need to be replaced.

There is no such thing as a hidden heating element.

Manufacture and model would be nice ohm out the bake element might be open some are in the oven cavity others are hidden below the lower oven plate and have to check from the rear by removing back cover in the bake mode the broil element element cycles on/off thats why you have some heat.

Good Afternoon Gwen - Try reprogramming the range by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes and turn the unit back on. If issue persists, then the unit could possibly be experiencing an issue with a wiring failure, EOC (electronic oven control), sensor probe and/or faulty bake or broil element. I would strongly recommend consulting a professional to narrow down the precise issue before investing in parts that may or may not be the root cause.

Bake and convection bake settings both use the bottom bake element to heat. It would be unusual for bake to work without conv. bake working. You also have pure convection which uses a different element surrounding the conv. fan on the back of the unit. If you press a feature and nothing happens it's the touch pad. If it comes on then turns back off it's probably the ERC (clock). If it comes on and wont heat only in pure conv. possibly an upper relay board or element problem.

Hello stevefer
Welcome.

You said, Your Electrolux built in wall oven, lights and digital display work fine, fan works fine, but the oven will not heat regardless of the mode (broil, bake, convention roast, convection bake)

First,
1.What is the Model Number and the year of your wall oven?
2.Did the oven light up and display with any error codes?
3. Did you try to turn the breaker off for 5 minutes to see if this will reset the system?

Perhaps the heating element is failing and may need to be replaced.
I will be able to better assist you when you reply with this information.
Waiting your response.

Bake- Normal convection- both upper and lower heating elements.

Conv. Bake- Semi-forced convection- both upper and lower elements, heat is then distributed throughout the oven via the fan.

Broil- radiation- The heat is radiated by the ifrared broil element.

Broil & Fan- Radiation and Ventilation- The radiated heat from the infra-red broiling element is distributed throughout the oven via the fan.
