Have a whirlpool duet gas dryer not heating, but running as for as the display is on and the drum turns. Model #: GGW9200LW0, S/N: MM3518408, TYPE: BADT-NAT-120600fi-EL22 .
Things I have tested so far:thermal fuse - OK, both by meter & just connecting the wiresignitor - test at 72 ohms of resistanceflame sensor - zero ohms of resistancehigh-temperature thermostat - zero ohmsthermistor - about 0.5 ohmsThings Replaced:Gas Valve Solenoid Setthanks for your assistance.
Welcome to JustAnswer
Are you saying you get continuity through the flame sensor and the high limit thermostat? does the igniter glow at all? did you test voltage to the igniter?
No you didn't miss anything, sounds like the igniter is good you're just not getting power to it, your absolutely sure you get continuity through the flame sensor correct? I you testing these with the wires attached? It's important you unplug the dryer and test these components with at least one wire disconnected from each component such as the flame sensor or the thermostats because you can get residual feedback from another component saying there is continuity so I suggest possibly retesting these with at least one wire removed from each component, let me know if you have done that already.
Okay well you did that right, there are two things that maybe issue in this, one is the control board itself is not sending the power to the igniter or two the motor centrifugal switch is not engaging sending power through to the igniter, these are difficult things to test however when the motor starts there is a centrifugal switch that kicks in and the sends power to the ignition system in the dryer, if this has failed then it's not connecting sending power to igniter, however this is not a real common issue with these, most likely it's in the control board, there are relays on the board which send power to the parts of the dryer once you start it, this should be a wiring diagram in the dryer somewhere possibly up in the control panel or inside the dryer somewhere, this will tell you which wires go to where off the motor and the control board, you need to trace these and see if you can find if it's coming from the control board on the motor that's the issue, these electronic machines can be a real pain in the neck to diagnose, if you can't find the issue will need to call it technician unfortunately, there's only so much I can do online, thanks and well wishes, Bryan
