Gas dryer no heat?

Whirlpool LGR7646AQO running on LP, cycles work, drum spins, Replaced ignitor,flame sensor and gas coils. Still no heat, ignitor coil will not glow. Checked voltage on blue and red wires to ignition coil and reads 3.5VAC, red wire marked 3V and blue wire marked 1V. Any suggestions?

Thanks, Dennis

Test the thermostats on the back of the dryer for continuity. If it is blown it will not heat. Part #AP3131939 Thermo fix or AP3094085 High limit thermostat.

part 3392519 continuity when running. ( Thermal fuse)
part 3387139 continuity when running and not running ( cycling thermostat)
part 3388697 continuity when running and not running ( High limit thermostat)
??

Did you check for continuity with the wires disconnected?

Thank you libertyappl, I remove the wires off the thermal fuse and disconnected the power and got no continuity. i then taped the wires together just to test and the dryer fired right up. so i will order a thermal fuse. Well i guess i spent about a hundred bucks to fix the dryer but i saved a thousand instead of buying a new one and learned a bit about dryers.
Thanks again for your help

Glad to help, You might want to hang on to the other parts, may need them later, they may not be bad.
