I have replaced the hi-thermal cut out that has blown twice. Checked air path for obstructions......none found. Cleaned lint screen, and entire assembly, and checked blower impeller housing. Blows hot air with good velocity without vent hose attatched. Will replace vent hose also. All other thermals checked with meter, none open. Am I good to go, or should there be something else to check before assuming it is now ok. Thanks
