Dualit 20245

Posted by Steve

This is a faulty MI-7 electro-mechanical timer from a Dualit 20245 toaster that my mother in law was going to throw away. The timer kept sticking, so the heating elements wouldn't turn off. If you weren't there to keep a close eye on it, your toast would be burnt to a crisp!

I had a look online and found that a replacement timer from Dualit was approx £50, whereas I could get the same part on eBay for £15. Since a new 20245 toaster costs about £120, it's definitely worth repairing!

Doing the actual replacement was fairly straightforward. Turn the unit upside down and unscrew the feet and any other screws in order to remove the bottom panel.


Make a note of which wire goes to which terminal on the back of the timer. Remove the connectors from the four terminals.


Pull off the timer knob to access the screws holding the timer onto the case. Undo the screws. Take it out.


Reassembly is the reverse of removal, but make sure you get the wires right.

It turned out that the replacement timer I bought had a slightly different design and the pins were labelled differently. I emailed Dualit customer support and they sent me PDF documents for both models of timer. Here they are:

I matched up the wires and got it all put back together. The other difference I found was that I needed to use machine screws instead of the original self-tappers, since the screw holes on the new timer are in metal instead of plastic.

I cleaned it up and sold it about eighteen months ago. As far as I know, it's still toasting.
