Kenmore Dryer will not heat

Dryer stopped heating. Have used service instructions inside with multimeter...fuse looks ok, the hight limit thermostat shows good, and when I check the three resistances on the gas valve coil - terminals 1 to 2 read 1399 (1365 +/- 25 typ), terminals 1 to 3 573 (560 +/- 25) and terminals 4 to 5 read 1305 (supposed to be 1220 +/- 50. This made me think the coil was bad so I ordered a new one...but it reads the same. Does anyone know if the terminal 4/5 range is really 1270 max or if 1305 is ok. Next step - I think - is to order replacement machine control electronics ($170). Any other suggestions...help???
