Oven repair ranges from simple element replacement to igniter and thermostat work. Electric ovens use bake and broil elements—test for continuity with a multimeter. Gas ovens need a working igniter (it glows but may not ignite). Convection fans can be replaced. Temperature calibration is often possible via a hidden menu. Our guides cover GE, Whirlpool, Samsung, LG, and Bosch. Always turn off the gas or circuit breaker before servicing. Oven elements are high-wattage—ensure the replacement matches the original rating.
