Heater tipped over now it won't heat up. I looked for a reset switch, there isn't one. What do I do

SOURCE: Lakewood oil filled heater model 5500

Follow up to my post of 13 January. Out of desperation, I took the heater apart and determined that an electrical fuse-like thermal overload device had opened on the neutral side of the feed to the heating element thus rendering the unit non-working. This device is wrapped in a sheath around the underside of the heating element's electrical connections where the element enters the radiator's core. If the element exceeds the rated temperature it apparently "blows" or electrically opens much like a fuse. The lights still come on but no electricity is getting to the element. When I removed this from the circuit, the the unit began making heat. Apparently, when the heater is on full (both switches on for the full 1,500 watts) the core temperature gets too high. So, I now use my heater on only the 900 watt setting and it's putting out plenty of heat. Today's high is 2F and the room is comfortable. I've no doubt the manufacturer would not condone this modification and I have no intention of turning my modified heater back on "HIGH." Therefore I do not recommend doing this yourself unless you are competent in electrical and soldering work and are sure you won't overheat the unit. Having said that Lakewood clearly has either a design flaw or a bad batch of heater elements or overload protectors out there. When I have time, I'm planning to send my defective protector back to them with a letter. But given that they never responded to my e-mail to their customer service don't expect much in the way of a reply. As they say on TV, don't try this at home.
