How Easy Is It to Repair the Wiring of an Electric Range?

Most electric range repairs, including the electrical wiring that controls switches, plugs, circuits and heating elements, are easy to diagnose and fix for those with basic repair skills. Many problems can be detected by a visual inspection, while some may require the use of a basic voltmeter. The most common problem with electric ranges is one or more stovetop elements that are not functioning. Typically, the problem results from the heating element, its plug receptacle or the control switch.

The simplest way to check the wiring for a non-working burner is to simply unplug it and switch it with another element on the stovetop that is the same size and working. If the replacement element heats up, the element is the problem. If the prongs of the element are coated in grease and grime, they should be cleaned to ensure poor contact with the receptacle is not an issue.

By lifting the range top off and removing the face plate on the control panel, all of the electrical wiring for the stove is clearly visible and can be inspected for any damaged areas. The repairer should inspect the burner's terminal block that connects to the element in question. If it appears burned or blackened, it needs to be replaced. The voltage can be tested on the block's terminals to ensure it is receiving the proper 240-volt current.

The last item to check is the infinite switch on the control panel for the specific burner. The range must be unplugged before checking the switch for continuity and examining the wires and leads for signs indicating overheated or melted areas.
