I have a 12 fin Radia Delongi oil heater that is about 4 years old. For a two week period there had been the odd whiff of fuel type small when the heater was on then one evening the lounge absolutely stunk of this smell and we had to air out the room all evening to get rid of the small. We turnrd the heater on the next day to teat it to find it didn't work. Is it completely kaput or can it be fixed. What do you think caused the presumed oil leak? There was no evidence of fluid leaking from anywhere. I have already emailed DeLongi and haven't heard from them. I would really appreciate a response. Thanks, Trudi Hill.

Make sure the unit is level, this is very important. Check for blocked drain tube, which runs from the bottom of the drain pan under the cold coil to the outside. Clear tube with a piece of coathanger wire, be gentle.

Threr are suppose to be two sounds comming from the window unit. One, the fan sound and the compressor sounds, (this compresses the refrigerants aove room temperatures (around 240*) & send it to the back coils and remove it to room temperatures and send it to the front coils which if enough freon, it will cool to at least 40*. Turn the thermostat all the way up or down while its off and see if you hear a clicking noise which tells you the thermostat is working which that what calls for cool. If it started loosing cools little by little, then you have a leak, and leaked all the freon out! If it stopped cooling all of once, then your compressor is not kicking in.

I have heard that there is a spray you can use that will not damage your system and seals the leak when it comes in contact with oxygen

The water in the machine comes from the cooling coil, and is condensate. This happens with all cooling systems. And no, no water in the cup will not burn the machine up.

Please reply if you are having problems with the unit.
