If the oven light, stovetop fluorescent light, clock or range outlet does not function correctly, often the problem can be a blown fuse or a tripped circuit breaker. Many electric ranges include a fuse in the 120-volt circuit that operates such items as oven and stovetop lights, the electric clock, convenience outlets, etc.
In order to check the fuses on your electric range, the following steps should be taken:
- Before repairs or testing can begin you must disconnect the electricity at the fuse panel, at the circuit breaker panel, or by pulling the plug. Make sure the power is off before proceeding. A jolt from 220 volts can be fatal, use caution!
- Refer to the owner's manual or to the wiring diagram for your electric range to locate the fuse you need to examine. The type of fuse used in electric ranges is usually the plug-type. This type has a threaded metal base (similar to a light bulb's base) and a flat top marked with an amperage rating. The fusible link is visible through a glass window in the top.
- Visually inspect the fuse to see if it has blown. The fusible link is visible through a glass window in the top. If the fuse is good, this link will be intact. If the fuse has blown due to an overload, this link will be visibly broken. If the link is broken and the glass window is also blackened, this indicates a short circuit. In either case, the problem that caused the blown fuse MUST be identified and corrected before installing a new fuse of the correct amperage rating.
REMEMBER YOU ARE WORKING WITH 220 VOLTS - USE EXTREME CAUTION!!!
