On electric ovens, the leading causes are a failed bake element ($150 to $280 replacement), a failed broil element ($150 to $280), or a failed control board ($250 to $500). Vintage Sun City electric ovens (GE, Whirlpool, KitchenAid from the 1990s) often just need a heating element replacement — a routine repair that keeps the range going for years.
On gas ovens, the leading causes are a failed igniter ($180 to $320, and one of the most common gas oven failures across all ages) or a failed gas valve solenoid ($150 to $250). Igniters are considered wear items and typically fail at 8 to 12 years of moderate use, sometimes earlier in households that cook frequently.
