Convections heaters use no moving parts. As the name suggests, they use the natural movement of air, rather than forced air from a fan, to distribute warmth. An electric element at the base of the heater draws in cold air from floor level, which heats up quickly as it passes through the element and then rises through a metal vent at the top of the heater. Very little can go wrong with a DeLonghi convection heater, but if your heater isn't working you can troubleshoot the problem to decide whether to get it repaired or buy a new one.


Step 1

Remove the plug from the main electricity socket before troubleshooting your DeLonghi convection heater. Undo the screw on the cover of the plug, using a screwdriver so you can access the wiring and fuse.

Step 2

Check the three wires are connected to the plug terminals. If any are loose, undo the terminal screw using a small screwdriver, and insert the wire into the hole. Tighten the screw.


Step 3

Remove the fuse from the fuse holder. Pry it out, using a small screwdriver. Put in a new fuse. Make sure it's the same ampere rating as the one you removed. The rating is printed on the side of the fuse. Replace the plug cover and insert the plug into the mains socket. Turn on the DeLonghi convection heater. If it works, you've solved the problem. If it doesn't, continue troubleshooting.



Step 4

Check the thermostat dial on the top or side of the DeLonghi convection heater. Set it to "0" or "*" then slowly turn the dial clockwise until you hear it click. Turn it slightly more once it's clicked, and check if the heater is working. If it is, the dial was set too low for the heater to start working. If you didn't hear a click when turning the dial, the thermostat isn't working and needs replacement. If the dial clicked and the heater isn't working, the heater element or the internal safety fuse needs replacing.
