Question about Black & Decker CTO650 1500 Watts Toaster Oven with Convection Cooking

No Oven but still Toasts

My Toaster Oven still toasts but the oven function no longer works. It does not heat up nor does the blue indicator lamp light. I've checked all knobs to make sure they are set to "oven". I was able to get inside the right-hand side, but no obvious non-functioning items (i.e. loose wires, broken wires, etc). I called customer service but they only recommended a new oven or a repair center. I have not tried yet but I can follow the wires logically and with a continuity tester to try to determine the faulty item. Any help would be appreciated (e.g. machine idiosyncracies, where to get parts, etc.) Thanks, merl

    Tried cleaning the contacts last night, no success.
    I then followed the wires to determine logically (without a schematic) how the current flows. If my continutity tester is correct, the switch that sets the oven temperature & selects "toast" no longer functions. This knob also physically sets the pressure on a set of contacts. Can this be repaired/replaced? Where can I get parts?

    I dis-assembled & removed the switch in question. The housing just snaps together so I carefully pried apart one end of the housing & noticed one contact was stuck in the open position, its arm was rubbing against the housing. A small file & a little elbow grease later the contact & arm were free floating. Snapped that end back on then checked the other end (since the switch was out) but looked fine. Re-assembled & the oven now heats!
    Thanks for all your help & suggestions!

    I have the same problem with a CTO650 that is less than 1 year old. I use to be an appliance repairman and have determined that the toast/bake control is bad. Black & Decker tells me that that part is not available. I can not find my reciept so warranty is not an option.

    can anyone explain how to fix this in simple terms so that someone who has no idea about taking apart and fixing a toaster oven can fix it. i opened up the right hand pannel and read the other solutions but am still confused. when i turn the button from toast to oven the switch still turns so that is not stuck, but i am not sure what else to check for...

    thank you so much

Never buy black & decker they don't supply parts they want you to rebuy the same junk over & over. its a shame this is what american companies have become buy japanese they last longer and make replacement parts.(I'm not unpatriotic just an informed consumer).

I did the same repair as merlin. Unplug from wall.. take the side panel off. Take knob off the temp. control. Loosen 4 wires that go into the module. (make a note of which wires go where)... take 2 screws out from the front of unit. The module can now be removed. use a small flat balde to open the bottom end.. slowly. .. a small ball bearing may come out (it's needed). Then you will see the contact arms that depress in to a small spring.. if contact is not being made. you need to file the housing that is rubbing on the one contact bar.. I also had to take it out and bend it a little to make it contact correctly.. once you have both arms depressing normally.. you can put back and test.. work good for me.. thanks merlin

Hello, I had the same problem on the CTO 650C. Toasting but no oven. It turned out that the housing of the temperature selection dial had melted slightly during use. There was a small obstruction inside the plastic housing preventing one of the spring loaded contacts from making a strong connection (possibly some plastic from the melting covered the contact). I simply removed the build-up and it is working so far.

Hi. I have a B&D toaster with a timer which works slightly different than yours, but probably close enough for this possible solution. My oven stopped working recently, but the toaster function worked normally much like your problem. What I did to get the oven working again was to first unplug the toaster power cable from the wall outlet, then remove the right side cover as you mentioned, get a small piece of sandpaper with fine grit and carefully sand between the electrical contacts that open and close when a knob or button is pushed. You'll have to try turning a knob and/or pushing a button while looking for contacts that come together and spread apart. On the other hand, these same contacts may be greasy as well. Take a Q-tip , trim it down with some scissors so that it can fit between the cantacts without bending them, dip it in alcohol and clean between the contacts. Again be very careful not to bend the contacts out of place. These contacts are in a tight space, so be patient and set aside an hour or so to perform this. This might get the oven function working again and save you the price of a new toaster. Good luck, tuneman

My Toaster oven top elements are not heating up on the toaster function

If the bake function still works you can keep it for that. But the heating/toasting elements are not meant to be replaced / repaired because the lawyers told them there is too much risk.

Another matter if still under warranty.

follow this steps and fix it. God bless you

f the oven doesn't work at all, make sure the circuit breaker or fuse is on at the electrical service panel and test the electrical cord . If the oven doesn't work on its toaster and oven functions, test the main switch . As needed, check the fuse .
If the toaster function doesn't turn off unless the door is open, test the solenoid, the switch and if necessary, the thermostast.

Location of the typical toaster oven's thermal fuse.
If the toaster oven stays on when the door is opened, check the main switch . If the oven doesn't heat, test the heating elements.

The blue light does not go on and the heating element does not wo

The problem is most likely the timer switch. They are very poorly made and tend to overheat causing eventual failure. B&D will be of no help and you will not be able to find the original switch. There is a switch made for Delonghi ovens that will work if you need a timer. The part # is 5218104600 and can be purchased for $10.98 at the Gourmet Depot website. This switch has a toast timer only if you turn it clockwise and turn counterCW for oven ON. Timer is only about 13 minutes. There is another switch that has a 120 minute timer. It looks the same and the part # is Delonghi 5218101800. May be harder to find. Another solution and a much cheaper one is to replace the broken switch with a single pole single throw toggle switch rated for 20 amp's at 120 volts. You will need to turn the oven on and off manually and you will no longer have a timer but at least you will be able to use your oven!

Top element not heating

I found that the heating element in the top front was burned off at the end. I removed the side cover and the ceramic insulator from the broken end. I then grabbed the broken end of the spring inside the glass tube and stretched it to where I could re-attach it to the connector. It now works after getting it back together.
If you attempt this repair, UNPLUG THE OVEN FIRST!
There is also a security screw at the bottom of the side cover.
