LG gas dryer wont heat

<< < (4/4)

On this dryer the sensor must send signal to the board that ignition has occured and then 90 vdc is sent to the gas valve right? So if his ignitor is firing up that means he has power coming from some relay somewhere other than the control panel. Therefore the  the control thermistat must be some sort of thermister connected to the main board. Are the coils remvable on the gas valve or do you have to replace the whole gas carrying assembly?

yes, transformer on control board

(120v AC) ignitor is controller by main board & flame detector & limit thermostats

gas valve is controlled by main board (90v DC)

I'm not sure about the separate coils (I'll check later)
