Troubleshooting a Bosch Tumble Dryer Model WTA74200GB/07: No Heat Issue and Early Shutdown. Despite the drum rotating normally and running for about 15 minutes, my Bosch tumble dryer fails to produce any heat, leading to incomplete drying cycles. This issue persists even though the moisture sensor, often a common culprit in drying problems, seems operational (as seen in your informative YouTube video). Additionally, I have attempted a diagnostic approach using an amperage meter, noting that the dryer only draws 170 watts of power. Could this indicate a malfunctioning heating element or thermostat? Or might it be related to other components such as the thermal fuse, drive motor and belt are all okay do you think it could be the control board? Your expert guidance on identifying and resolving this issue, including insights into the dryer’s electrical and mechanical systems, would be highly appreciated. Jim Hawthorne
