Hi, replace the oven temperature sensor if "F2," "F3" or "F4" is displayed. "F2" indicates the oven temperature is too hot and the oven temperature sensor is suspect. "F3" or "F4" indicates the oven temperature sensor or shorted or open.

F3 usually means, that the oven temp. sensor is bad and one need to replace it.
The fact, that it's not heating tells me, the fuse in the back also needs to be replaced (requires pulling out).

Error E3-F3 says that the Oven temperature is too high(Clean mode).You might have to replace the Oven Temperature Sensor(RTD).

While using the self clean feature you burned out the oven temp sensor.
Replace the oven temp sensor.
Do not use self clean on any oven unless you want to replace parts,

The F3 error on this model is an open thermostat circuit. The F6 is a control or loss of power. Make sure the unit is plugged into a good 120 Volt outlet. Test this outlet with a power drill or lamp, wiggle cord in receptacle, if no other test experience or equipment is avaliable. Check the thermostate in the oven for physical damage. There may be a loose connection in the oven. This would require a good technican to find.

i think f3 error code has something to do with the temp probe maybe it is the problem. the temp probe is located if you open the door directly in the back wall. it looks like a prong. should read 1100ohms the f2 error code though usually has something to do with the keypad i would check all the connections maybe they are loose.

f-3 means the oven temp sensor is bad. replace the sensor and problem solved
