I've got a several-year-old Holmes floor model space heater (no model

I assume it's a thermostat problem. I suspect it's fatal but if anyone
knows of something that might help you'll save me the expense of a new
heater.

May be the thermostat, could be the safety switch that turns if off
when knocked over. Or some overheating sensor. Does it go back on by
itself once it shuts off?

Problem is, the part will probably cost about the same as a new
heater.
