This failure mostly due to M1 stator winding open or burn. Check the M1 (yellow, blue wire) Plug terminal contact normal. Unplug the plug wire terminal block with a multimeter R × 1k M1 ​​measure both ends, the normal resistance of about 1.9kΩ, if it is ∞, explained winding circuit. M1 has burnt roast split out phenomenon is a serious damage, re-weld can be put into use. If the winding has burnt roast phenomena are severely damaged, due to the small diameter wire windings and the number of turns, not rewound, available TM30MU01 type, 250V, 8A integrated timer fire selector replacement.83qservice manual download site
