Before I run out to replace this 15[?]yr old Magic Chef, I thought I'd
ask for a second opinion.
I took it apart yesterday because it wasn't heating. I checked the
limit switch & thermostat & both had continuity. Put things back
together & it seemed to work fine. I had a small load of clothes
So I put in a full load & went away. When that was still wet after
a couple hours I went back to the drawing board.
With the dryer apart I fired it up this morning & watched the gas
ignite fine, run for a couple minutes, then cycle off like it was
supposed to. But when the dryer called for more heat I could hear
the click and see the igniter light-- but there was no gas. It would
try to light for 5-10 seconds, then shut off for a minute-- then try
to light again.
I rechecked the thermostat & limit switch & they both still had
Then I noticed the igniter sensor that doesn't seem to be mentioned in
the schematic. That tested open when tested with my ohm meter.
When cool, it tested closed & the dryer ran a single cycle again
before shutting the gas off. [The igniter still lights & tries to
light the gas.]
This is the part-
I'm guessing that this $30 part might be the culprit, but it looks
like it operates on light, not heat, so I'm hesitant to spend $30 for
nothing. [My limit for this beast today is $100]
But then I checked the coils while cold & hot.
When cold I got continuity between terminal 1 & both of the other
terminals on the 3 terminal coil. The 2 terminal coil had continuity
between the 2.
When hot, I only get continuity between terminals 1 & 3 on the 3
terminal coil. [and between the 2 terminals on the other] No
continuity between terminals 1&2 on the 3 terminal coil.
It is a Magic Chef YG20FN1 .
My instincts say get the coils-- but I'd hate to get them. . . then
the flame/igniter sensor. . . then a new dryer. [The gas valve
alone, if that is the culprit, would send me off in search of a new
dryer.] Does the above test sound like a faulty coil?
