[quote=wpstrassburg;820865]Thanks Joe. I’ll give it a shot and see what i get for a defect. I jumped the thermocouple and the gas didn’t fire, so that doesn’t look to be the problem. I disconnected the humidity sensor, but didn’t jumper the wires together as it didn’t look like the sensor usually has power between the leads due to the design of the sensor. Can I jumper the humidity leads together without damaging the board?
I’ll check the door switch as I don’t remember seeing the light going on and off. Would the dryer even start if the door switch was failed open?
Gas will fire for just a second or three before it trips out to the E68 code. Would it even fire if the flame sensor is bad (open)?
Is the control thermistor the sensor on the motor or the one on the back right near the drum or is it the high limit stat?
Will any sensor faults come up as an individual code or a generic one besides the Error codes listed on the tech sheet?[/quote]
WP, Manipulating the sensor wires won’t really solve the issue, and jumping the wires will make the control “think” the clothes are wet and cause the dryer to not shut down. Besides there is the possibility of damage to the control board(even though very slight).
No, the dryer would not attempt to start if the door switch circuit was defective or stuck in the “open” position, there’d be no circuit or L1 voltage (120 VAC)to the motor through the door switch, and the dryer would not start.
If the flame sensor were defective, the burner would not even attempt to glow or ignite.
The Thermal limiter is located on the right rear wall of the dryer cabinet. The Hi Limit thermostat is located on the top of the heater housing (shroud) and the control thermistor is mounted on the front of the blower housing. The thermostats need to be “closed” at room Temp. and the thermistor should be approximately 50 K ohms on a meter test.
The heater and sensor circuit failure codes are listed on pg.1 of the tech sheet, there are a couple of codes for the control thermistor and one ( E5B) for a no heat situation. The information advises of checks to make at the heat circuit components. The majority of the error codes pertain to the control board, so when you conduct the diagnostic error codes, you may want to write them down, so you can compare them to the list and determine the possible issues.
