Electric heater does not blow hot air

My white-Westinghouse air heater of model WWRH3010 only blows cold air, not hot air, when turn ON. Checked heating wire-resistance, there is not broken from outer view. Before it stops blow hot air, seems heard a light burnt sound, Is there any inside thermal part or others needs be checked (dis-assemble)? Is there any part maybe dead and needs be replaced w/o big cost (otherwise buy new one)? Thanks



?

There are two safety thermal devices in that heater.
One is cycling and if it gets too hot.... opens and causes the caution light to come on.
The other is a thermal fuse that blows open on high heat.
It can be replaced but you'd need to open the unit to identify the value off the part.
You want the part with the crimps as it cannot be soldered in place.
Example only
