Toasters aren't just for toasting bread anymore. If your toaster doesn't, fix it!
Remove the carriage lever and unfasten the cover panel.
Inspect the latch assembly and check the carriage for debris that may stop smooth operation.
A toaster is an electric heating appliance with a timer, carriage, and latch. Most pop-up toasters work in the same manner. A slice of bread or other appropriate food item is placed through a slot in the top of the toaster and into the carriage. A lever lowers the carriage. When the carriage reaches the bottom of the chassis, it latches in position, an internal switch turns on the heating elements, and a timer starts. Once the timer finishes its cycle, it turns off the elements and a solenoid releases the spring-loaded carriage that pops up the toast. A toaster oven works differently to do the same thing on a wider variety of foods.
Service the latch assembly:
Unplug the toaster from the electrical receptacle.
Remove or open the crumb tray and empty it. Turn the toaster over above a trash container and carefully empty out any crumbs before continuing.
Remove the toaster cover by removing levers, knobs, and fasteners (typically on the underside or underneath labels).
Inspect the latch assembly for obvious damage or crumbs. Use canned air to clear debris from the latch assembly.
Move the carriage lever up and down to check for smooth operation. If the carriage moves stiffly, sparingly apply an appliance lubricant on the latch rod.
Verify operation of the latch to ensure that it works smoothly. If necessary, carefully bend the latch to make sure it catches properly.
You also can inspect and test the heating element(s) while you have the toaster open.
Service a solenoid:
Remove the crumb tray cover to access the solenoid switch, typically located near the thermostat on the controller side of the toaster.
Use a continuity tester or multimeter to test the solenoid switch. If faulty, remove and replace it.
To replace the solenoid you may need to disassemble the toaster, as above. If the solenoid is installed with rivets, replace the chassis as a unit or the entire toaster.
