This safety feature stops the magnetron to avoid overheating, often triggered by loose wires, burnt sensors, or humidity damage in models sharing GE\/Whirlpool DNA. Unlike Samsung SE (keypad), F1 ties directly to thermal protection, echoing prior F2 thermistor shorts but focused on disconnection.<\/p>\n<p class=\"my-2 [&amp;+p]:mt-4 [&amp;_strong:has(+br)]:inline-block [&amp;_strong:has(+br)]:pb-2\">In Kenya&#8217;s variable grid, F1 spikes post-blackouts when capacitors retain charge, mimicking faults.
