When troubleshooting an energized electrical circuit on an electric heat section, if 244 volts is measured across the element at points A and B but no amperage is measured, what is the likely problem?

In the scenario described, measuring 244 volts across the element at points A and B without any current flow indicates that the electric heating element is likely open.

When an electrical circuit is energized, voltage present without any measurable amperage typically suggests that the circuit is not complete, which means there is no path for current to flow. In the case of an electric heating element, if the element is open, there will be continuity issues that prevent current from flowing through the element, resulting in zero amperage despite the presence of voltage across the terminals.

An open element means that a break in the internal circuit has occurred, often due to a failure in the wire or the heating material itself. This situation results in the heating element not functioning, even though the circuit is energized and voltage is present.

Understanding this helps clarify why the other potential issues, such as a short circuit, short to ground, or an open fuse link, would not fit this scenario. A short would cause high amperage, a short to ground would similarly register as amperage, and an open fuse link would disrupt the voltage supply. Therefore, the evidence points decidedly to the heating element being open as the root cause of the issue.
