Our Bosch WTA 3510 will not heat up when using any of the Auto Dry Cycles. It will only heat and dry using the "Timed Cycles".
I checked the following:
Lint filter is clean
I cleaned the humidity sensor inside the door opening .
Heating resistors E2 and E3 measure correct resistance.
The Hi-Limit Overheat Thermostat B9 has continuity - I am assuming it is OK.
Two items I found not be correct:
[LIST]
*]On the front operating panel, from all of the "Moisture Level Indicator Lights" in the left top corner of the panel, only the LED "Drying" lights up when dryer is running.
*]The Temp Sensor NTC R2 is open (meter should read 18 to 22 kOhms) - I am assuming that it is defective and the reason why there is no heat in the Auto Cylces.[/LIST]Other than replacing the NTC R2, what else would need replacement, if at all?
Thanks in advance for any advice.
