Possible Causes

Blocked lint filter, restricted exhaust duct, failed blower motor, faulty exhaust NTC sensor

Safety first: Disconnect power before cleaning or disassembly.

Reduce exhaust temperature:

Clean the lint filter and any secondary filters thoroughly.
Inspect and clean the entire exhaust duct to the outside vent; ensure the vent flap opens freely.
Check blower motor operation; if the fan is not running at full speed, test and replace the motor as needed.
Test the exhaust NTC sensor for correct resistance; replace if faulty.
After corrections, run a test cycle and monitor exhaust temperature if possible.
