How do I get my oven to work again?

To get your oven to work again when it will not heat, will not turn on, or shows error, you need to troubleshoot power, controls, and heating components. First, check power supply: ensure oven is plugged in, check circuit breaker for electric ovens that require 240 volts from two breakers, reset breaker if tripped, for gas ovens ensure gas supply valve behind oven is open and 120-volt outlet has power. Second, check control lock: if control lock light on, press and hold Control Lock or Start button for 3 seconds. Third, perform hard reset: unplug oven or turn off breaker for 5 to 10 minutes to allow control board capacitors to discharge, then restore power, this clears error codes like F1E0 after power outage. Fourth, check door: ensure door fully closed and latched, as oven will not start if door not closed. Fifth, test heating element: for electric ovens, if oven does not heat, bake element at bottom may have burned out, visible as blistered or broken coil, replace element at 20 to 60 dollars. For gas ovens, if oven does not heat but you hear clicking, igniter may have failed after 3 to 6 years, costing 30 to 80 dollars, it glows but does not open gas valve. Sixth, check temperature sensor at back wall inside oven, if oven overheats or underheats. After checking, run empty bake cycle at 350 degrees for 10 minutes to test. If still not working after reset and element check, control board may have failed and needs professional replacement.
