Richard for Model Number GGW9200LQ0 I have a Whirlpool Duet gas dryer that won't dry clothes. Cleaned out the exhaust tube & inside of unit. Wasn't that bad due to previous cleaning on yearly basis for efficiency purposes. I have gone thru the diagnostic test on the board & it shows no error codes. I've checked the thermal fuse & thermistor & gas coil & those readings are as they should be. Glow coil comes on & ignites gas but flame shuts off after a few seconds & the process begins again. It has a blue flame but doesn't appear overly robust. Looking for ideas!
Answer Richard, You may want to recheck the vent system and hood, make sure there aren't any kinks or clogs, or the hood isn't crushed or blocked. Remove the front tumbler support and remove any lint that has built up in the duct, under the filter and any debris in the blower wheel and housing. If all's OK, chances are you have a weak set of gas valve coils. Run the dryer for 15 or 20 minutes, then test the coils for proper resistance readings, coils will check OK when "cold" but you'll see the resistance change once the gas valve has cycled a few times, if they're weak.
