Why did my wall unit space heater quit working?

My heater is suddenly not working. I have tried it in different working outlets. How can I tell if the problem is with the bulb or the machine? I will try to get the bulb out and see if it looks dark on the ends...and if there is movement inside when shaken, as with incandescent bulbs??? Need replacement bulb for Sears quartz heater 1500 watt model 344.7147.

There could one of many possible failures preventing the heating element from working.

Failed tip-over switch

Control

Heating element

Burnt wire connection

The heating element is inside the glass tube and if element wire is not burnt in two, the heating element is likely OK. The element can also be checked with an Ohm meter for continuity. If the element is found to be burnt out, the heating element is NO LONGER AVAILABLE.

In order to diagnose the failure will require a volt/ohm meter to check the continuity of the heating element, control and the tip-over switch.
