My dryer blows the thermal fuse without going into overheat as it used to. I have replaced the thermal fuse twice and the thermistor. My dryer wont go into diagnostic mode.
Clogged or restricted exhaust vent air flow is the most frequent cause of a thermal fuse blowing. Check the lint screen for lint or a build-up of debris that could be inhibiting air flow through the dryer. … Check the flexible vent hose behind the dryerfor kinks or clogs.
