Disconnecting the old transformer

Now that the electronic parts are clearly visible and easy to reach, the connections to the electromagnet can be unsoldered. Initially, only unsolder one of them.
With a testmeter on the resistance or Ω range, touch the two probes together and ensure the meter reads zero. Now touch one testmeter probe on the end of the now free electromagnet wire and the other on the other wire still soldered to the circuit board.
If you get infinite resistance then the electromagnet is faulty. Unsolder the other wire, remove the electromagnet by removing 2 screws, and replace.
If the electromagnet shows a resistance of a few hundred ohms then the fault lies elsewhere. Check the circuit board for any obviously overheated components, and if you are able, check there is a good connection to the circuit board from a tap on the element which taps off a small fraction of the mains voltage.
DO NOT attempt to test the toaster whilst dismantled as this would constitute a serious electric shock hazard.
Follow the instructions on properly using a soldering iron. Failing to do so can result in injury.
