My heater will turn on but does not blow heat

The thermostat has failed. It is closed circuit all the time.

Check to see if it has a fuse. it might of blown it.

Use a vac on blow or a air line to blow it clean

I don't know how to make your heater work again, but I do know (from long experience with Lakewood 707s) that the setting knobs often fail to function properly even if the heating element still works. My solution is to plug the heater into an adapter with an on/off switch on it and use that to control the power. I leave the setting knobs on the heater itself in the position where I usually use them (max heat). These are excellent heaters except for the knob problem.

Thats a thermal limit, youre heaters junk!

I just drill a hole and I put old oil in my used motor oil

I went to buy a new oil filled heater because mine was blowing the breaker. After I bought two, I heard the sales rep telling a customer to store the heater on it's side or upside down or give it a good shake to loosen the oil from the bottom. So, I went home and tried this...it may take a couple of times before it stops blowing the breaker, but it works.

Some of the newer models have a thermal fuse which may be blown. It doesn't look like a normal fuse at all. It is similar to a transistor in looks and should have continuity from one end to the other. It will be tied in to the incoming power cord inside the heater, and may be covered with rubber coating within the wire. It will look different when you notice it. Sometimes its too far down inside where the heat causes it to blow prematurely. The purpose is to cut the power to the unit in case it overheats. You can get one at radio shack for less than a couple of bucks. The older models don't normally have one, but I would suggest you put one in it if that's the case.
