A detector for detecting the condition of an ignition assembly in a burner is disclosed. The flame in the burner is ignited in a fuel medium by means of an electric arc across a spark gap in the ignition assembly. The assembly is substantially inaccessible for the purpose of testing through direct electrical contact without disassembling the burner. A detector detects the radio frequency emission of the arc at a distance from the burner and the control system for the burner. The output of the detector is rectified and displayed to provide a visual indication of the condition of the assembly.
