The contacts for these toasters fail. The plasic cam that depresses the contacts also can melt. The design is poor and no replacement parts are available. When selecting a setting, if the selection is not exactly perfect, the contacts arc and eventually fail. Unless cuisinart changes the selection cam to a solid state or relay, this failure will continue to happen during normal use. If your unit works properly do not switch the function setting while heating, this will cause the contacts to arc and erode the contact surface. This posting is applicable to the TOB-30BC, TOB-30BCC and probably all TOB-30XXX models.

    You can try to clean the contacts with alcohol (and/or very fine sand paper) as stated in other discussions, but the fix is a near term solution and eventually the contacts will arc and pit again. This leads to higher temperatures across the contacts and if the contacts fail before the plastic cam melts, your free to address the contacts for cleaning again. Just remember this failure will occur more frequently each time. Once the cam fails (melts) your out of luck. Write Cuisinart and tell them how unhappy you are with your toaster oven. If you get the same response I did (we only will replace it under warranty) then feel free to recycle it (or throw it away) and spend your money on a delonghi (no affiliation - my hand me down 7 yr old one keeps working great) or another brand. Companies these days should have better quality control on the products (from china) they slap their name on.



    For the record, mine TOB030 has about 10 hrs run time on it before it failed @ 1.5yrs old. The inside is still brand spanking new!



    Just my 2 cents.

    My TOB-30 failed after 5+ years. I opened it up and found that the cam had melted on the first contact. Ugh.

While the contacts on the cam do get dirty from the arcing that is not the main reason these units have all been failing with the same problem. The "toast" problem is caused by bad capacitors on the 2 small circuit boards inside. The reason the toast function fails and the rest of the oven works is because the toast function has a seperate set of electronic circuits for the timer and heating elements. If you change out the 4 electrolytic capacitors this will fix the problems. There are three 220uf 16V and one 1uf 50V. I would change out the 220uf with at least a 25V since this is activating the 12v relay circuit.
Before changing these out the Toast function would buzz when selected, it should not...this means the heating elements are on, though just barely. Next, the unit would just go out or stop working when you press the Start button....and lastly the timer stopped beeping. After replacement all functions returned to normal. My guess is that the heat from the unit (and a current limit resistor on the circuit board) simply dries these caps out and they fail.

The best solution based upon the dates of the post are that it has a 3 year warranty.

I have the same problem. It is due to a bad relay switch in the toaster. I have found that for now, my toaster will work if I leave it on the "TOAST" function rather than "OFF" overnight. I think it lets some current or voltage hit the relay and encourages it to work.

I will try to replace the relay and post a "how to" on that when it is done.

May all of your toasting be succesful.

    I replaced the relay switch, but the problem was not fixed. Du-oh! Looks like it wasn't the relay after all. At this point, I'm not sure what is wrong, but my work around seems to work still.

I have a cuisinart toaster oven. Model TOB 30BWC. The selector/timer dial doesn't work so the oven is always on when it is plugged in. I would like to get a new dial


Looks like replacement knobs are not available from Cuisinart.
However, any 1/4" shaft knob with setscrew should work.
If you have a Radio Shack still in business near you, they are blowing them out for under a buck a knob:
RadioShack Hexagonal Control Knob
Other styles and sizes are also available.
If you do not feel like looking around, here are a pair of universal knobs that should work, although they do not look the same:

Lower heating eliments don't heat or glow. Only top ones work


The elements are not orderable, but you can call Cuisinart with your serial number - the product has a 3-year warranty, and that is definitely a defect - will they glow if you put them on Toaster setting?

Broiler element


Its an on or off thing. No way to control the flow of electricity.

The elements are bigger than necessary to heat the unit quickly, the problem you have is a bad thing with food that burns easily but a good thing that makes these units come up to temp so quickly after turning on.

Unfortunately the only thing you can do is put more space between the element and your food or use aluminum foil (not suggested, its too close to the burners).

Eventually the contacks will fail (unless you are one of the lucky ones).

Good Luck
