White Knight tumble dryer
Fault
The tumble dryer turned but produced no heat, even though its rear heater and thermostats appeared sound.
- Assessment
- Testing beyond the rear heater assembly found an open-circuit forward thermostat in the air duct. The ducting was checked for lint restrictions before replacement.
- Work
- We fitted the correct forward thermostat, cleared the accessible airflow path and refitted the duct and panels.
- Parts
- Forward duct thermostat.
Checks and outcome
A test load confirmed heating, airflow and temperature cycling. The dryer produced warm air and continued running without overheating.
