Sparks inside radiator when he automatically kicks off
My di Longhi oil-filled electric radiator seems to work reasonably well, but two things concern me. When the radiator reaches a certain temperature and automatically shuts off, you can see electric sparks through the vent holes on the side. (We are very careful not to have anything on or near the radiator.) Also, the circuit breaker went off recently, while the radiator was on.
Is the unit defective?
Should I suspect problems with the wiring in the wall?

Re: sparks inside radiator when he automatically kicks...
I would suspect the unit is at fault. the sparks from the inside of the unit indicate a short from hot wire to ground (unit itself). this is verified by the tripping of the circuit breaker. I would not use the unit anymore till the short is clean.
this is potential fire hazard.

1. is there coolant in radiator ? yes
is there a problem with thermostat device in cooling system. Google this if you do not understand how a thermostat works or how to check it. Youtube is also good place to research .
check if cooling fan rotates when engine running or radiator is hot. some cars have electric fans that kick in when engine is hot. no Put coolant in radiator run engine in idle check for water leaks
around rubber hoses, from radiator core , from engine welsh plugs
check heater core inside car does not leak.
2. is there adequate oil in the engine ? no
put some oil in engine check dip stick put a little bit in if not at correct level. DO NOT PUT WHOLE container of oil in car engine at once and over fill it. expensive to fix.
degrease engine - clean engine
check over time to see if oil is leaking from engine. yes
good one less thing to think about
1st, check the electrical cord plug; because of the hielectric demand, thesaes plugs overheat and form a burn coating on the prongs that stops the hilevel of electric but allows a small level ofalaectric that still lights the lights but no power for heat.
2nd, the thermostat is not making contact: it is a bi-metal contactor that sometimes burns or loses its strength and no matter where you turn it it wont work. You can simply cross the terminals of the thermostat to see if you get electric flowing (you have to open the oen housing to do this.
3rd, the element could be burned-out or (as often happens) the connection to the heat element burns-off. Again, you need to open the end housing and look, or take it to a small appliance repair place.
Unscrew the four screws holding the front faceplate on (two are on the bottom of the radiator). From the bottom end gently pry up the faceplate, it will stay attached at the top end near the temperature selector. Look inside and you will see a black bridge like piece of metal with a plastic and metal thing stuck to it's center with two wires leading into it. It's basically a connection that melts when high temperatures are reached, therefore it must be replaced (pictured). You can bypass this by prying the metal bridge out, removing the wires leads from the switch and connecting them using a wire nut. BE AWARE THAT THIS WILL OVERRIDE THE HIGH TEMPERATURE SHUT OFF MECHANISM, so don't use it for drying off your coat again.
To whom it may concern
Yesterday, I communicated with one of your colleagues by the name of Ginko. He advised me to contact the factory in New South Wales, Australia by phone and e-mail.
I rang through and they weren't particularly helpful. They said call a service agent with the details of the product, I was supplied with a contact phone number. The service agent was unable to help me, they said they would call back and as yet they haven't.
I also had sent an e-mail to the the customer service reprentative for De Longhi, who responded the following day, and gave me a list of five outlets in Melbourne, which are able to order the part for me. I duly contacted the nearest supplier to myself, rang them and they said they will order the product (after taking down the product details and my home phone number) and will contact me when it arrives.
Thanks to Ginko for his time and help. I will wait to see the outcome of this. This is the most recent update to the situation.
On some car, like in my renault, there is an additional fuse box near the engine. Buy the complete Haynes manual for your car, it will show diagrams and picture of all parts, and eventually tell you which fuses and parts are involved in the radiator fan wiring. Once you have the diagram you follow the circuit leading to fan and find the fault, it shouldn't be complicate.
