I purchases a Kenmore gas dryer in 2007. The unit has been problematic from the
beginning. I again have no heat. The thermal fuse (AP3132867), cycling thermostat
(AP3131939) and high limit thermostat (AP3084674) are all shorted at room temperature as
they should be. Upon start up the system tries to light with the igniter, but I get no
gas. The problem is definitely the coils. On the three terminal coil I have just over
1380 Ohms between the left and middle pins, but have no conductivity between the middle
and right pin.
I now have ten sets of dead coils with the same failure mode from one dryer. That means
I average about six months on a set of coils. Should I be thinking about replacing the
gas valve? My thoughts are that I have a sticky mechanism that requires more current to
actuate, and I ultimately burn out the coil.
ANSWER Hello Donald. Based on the information you provided, it sounds like the valve 279923 is bad and will need to be replaced. The power coming to the valve can have this effect on the unit as well. Make sure there is 120 volts coming to the dryer. If so, replace the valve. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
