Timer 5210910021

The timer was an exact fit replacment for my Delonghi Dragon Radiator and works well despite the part number being slightly different than my original timer. However, it's a bit tricky to replace as you must first remove the entire front metal panel of the unit to disconnect the timer, then you must remove the plastic facia trim which is held in with 4 plastic snap-in tabs and 3 screws to remove the timer. Hard to undo the tabs without breaking them but fortunately by removing only 2 of the 4 tabs I got enough movement/space between the trim and the panel to remove and replace the timer (in the reassemble, the remaining 2 tabs and 3 screws seem to hold the plastic fascia in place adequately).

Most excited to buy here.

The part was exactly what was replaced. The heater is now working as before.
