If any of the reading is wrong then the transformer has to be replaced. If there is nothing wrong then remove the wires from the transformer primary windings and check for 120VAC between these wires while the control calls for heat and the door is closed. Post the results. Here are the break down diagrams for the Frigidaire microwave Model FMT148G1W2 Gene.
