I removed the top, back and kickplate panels. After vacuuming out a ton of lint, I started doing some basic troubleshooting. I ran the front panel diagnostic tests as described in the tech sheet (MORE TIME -> LESS TIME -> MORE TIME -> LESS TIME) and all of the console switches and LEDs seem to be fine (i.e. pressing each switch controls the LEDs as described in the Tech Sheet).
The moisture sensor also appears to test out: when I bridge the two metal strips I get a beep and the two-digit display reads "02" (the Tech Sheet says that "a software revision number" displaying indicates the sensor is OK).
However, when I open the door in diagnostic mode, I get a beep tone and a "09" is indicated in the two-digit display. The TS says that I should get a beep tone and "a number and letter" on the display. This test seems a little inconclusive since the "09" could be interpreted as "O9" in which case I have a letter and a number on the display. The door switch test section of the TS it elaborates that the "number and letter" should be "i.e., '0E', '0G', '1E' or '2G', etc." When I close the door (or close the switch) the display goes back to "88," which is as expected.
In the "Moisture Sensor Test" section of the TS, it again has me put the dryer in diagnostic mode and open the door. Again I get a beep and "09" on the display. Here the TS states "if a beep tone is heard and a software revision number is displayed on the console as soon as the door is opened, a short circuit exists in the moisture sensor system." So, is "09" a "software revision number"?!? Does this "09" indicate a short in the moisture sensor or a faulty door switch circuit or neither?
So from the inconclusive door switch test, and the moisture sensor test, it appears my issue may be in the moisture sensor. I didn't have the time/patience this evening to complete the moisture sensor test. But before I invest the time in doing so, I just wanted to get a reality check: Does a diagnosis of a moisture sensor issue fit at all with the symptoms I am experiencing?
Other diagnostic tests I ran:
- tested the thermal fuse which had continuity, i.e. it is "good".
- tested both the main and start winding coils on the drive motor and both tested within the specified range for resistance.
- test the belt switch which passed
Before these symptoms started I had disconnected and reconnected the dryer (to paint behind it). When I reconnected it, I forgot to turn the gas back on to it. My wife ran the dryer and it tumbled, but obviously never got hot. Once I turned the gas on, I started the dryer and it appeared to start and run normally (at least for the few seconds I remained in the room after starting it). A bit later, my wife noticed the current behavior when she attempted to re-run the cycle. It didn't appear to have dried the clothes much (at all) when it "ran" after I started it.
So, any guesses as to what my problem is likely to be? Any suggestions on what troubleshooting steps I should take next? Any assistance you can provide would be greatly appreciated.
