I have a Patton Digital Plus accutemo oil heater. I bought it new and I have had it a number of years. I went through your current line of oil heaters and could find my model. I can't find the manual and I don't know how to turn off the machine so I have to pull out the plug to turn it off. It does not have a simple on/off switch. Can you tell me how to turn on and off the heater that works exceeding well.Thank you. Malcolm my email is [email protected]

The DeLonghi 5108 has no thermal fuse. There was a problem with the control panels and DeLonghi was to offer free repair. Details on http://www.cpsc.gov/cpscpub/prerel/prhtml91/91108.html
which includes a toll free number.

Hi, Here is the link to the manual. I think something like 'thermo coupling' probably means you need a technician!

check that the rocker switch inside isn't stuck, when the rocker swings it shuts the unit off. if it is full of dust it may be stuck. may just be bad.
