What parts did you end up getting?

Flame sensor, main board, ignitor

back to square one ....

The valve resistance is 1995 ohms and the ignitor is 185 ohms. 


Square one...  I had a appliance repair tech tell me it was the coils, without even looking at the dryer and that it would be $375 to fix.

Valve resistance.... Do I test across the terminals of each valve with the plug connected and and 120v AC unplugged?  Also, will this tell me if the coil is stuck or too weak to stay open? (that's what the repair guy told me)

Unplug the dryer

Disconnect the wires at the gas valve coil # 02

Check the ohm of the # 02 valve--if not within spec or "open"--replace the GAS VALVE COIL ASSEMBLY.

With my ohm meter on 2k, I get 1.922

Did this ever get resolved, I am having pretty much the exact same symptoms with the LG 7188WM, I suspect the control board, but after reading your posts I'm not so sure.. would be nice to find a smoking gun, but it is eluding me thus far.

Most of the time those coils fail. Unplug the dryer AND coil to check the ohms.
Those coils are expensive and fail often.

About the icons: The beer is tip link, if a tech saves ya some money buy em a 6 pack. The small green square=personal message. The green dot is a link to my web page on appliance repair and other general BS I love to post. The letter sends me email.
I love fan letters! LOL
