Part 2 Dryer with no heat: • Kenmore Gas Dryer 400 ...
Problem:
Dryer Take too long to dry. Got heat when turn on and running but when it finished, the cloth is still too cool to touch.
After replaced the 2 gas Solenoids and clean out front and back areas including vent duct and blower motor casing,
it's still not working. Seem like cooling cycle kick in too early and stuck in that position.
When heard a buzzer, immediately open the dryer door and feel no heat, just cool clothing.
Test or checking::
Dryer Ignitor on, got flame. Check the following for continuity:
1. Cycling or Operating Thermostat (4 pins)
2. Thermal Fuse
3. Thermal Cut-Off Fuse
4. High-limit thermostat
ALL are good.
Solution: Blindly replaced Cycling or Operating Thermostat (4 pins), Thermal Cut-Off Fuse, and High-limit thermostat on the back of the dryer and the problem is solved.
