My pelonis oil heater has a diode? on the blue power wire behind the end cover. i think this is why mine does not work. can you help me find a replacement?

Check for power at the heater. Switches can be tested. Don't just replace on a guess. If you don't have a test meter, but drop it into a local appliance repair shop.

burnt thermo fuse or element. be sure to connect any wires tightly if you replace thermo fuse. test it with a mulimeter should show less than 1 ohm. no you do not need to add oil, if the unit leaks throw it out.

Unplug it, then open it and inspect for a loose wiring connection. If that doesn't help, then jumper across the tip-over switch to see if the switch is bad.

they r cool on the on line help and do respond

I would definitly try to give your heater a through cleaning before before giving up on it. Remove screws that hold back cover on and remove cover. There shoulb be a fiter directly behind it,remove it and give it a through cleaning. I don't know on the new ones if the filter is made of foam material,the older ones like mine are.It is safe to wash them in warm water and a little dish soap. Rinse fully and pat dry. Clean any lint,hair,dust or any other foreign material from fan motor. Blow it out with compressed air if you can. You can use a tooth brush to clean around motor shaft and air ports on motor. You can use a couple of drops of fine grade machine oil on motor shaft,such as 3 in 1 oil or WD-40. Wipe off excess. Lightly brush heating elements and reassemble. I hope this works for you.

The oil does not circulate or lubricat anything. It just holds heat. No harm done.
