Product review (5 stars): Fix for intermittant heating
Kenmore gas dryer worked great for years then started not fully drying. Heat was intermittant and getting less and less with each load over the course of days. Vacuumed out lint in exhaust line but didn't fix problem. Looked through viewport on bottom of front panel (remove small plug) and saw igniter was getting red hot but no gas was flowing. Replacing these was the fix. Look for youtube videos on how to open front panel. Working well for a couple months so far.
