Thermador Model#SMW272zp keeps tripping breaker

During self clean mode the oven popped the circuit breaker. Every time I attempt to put the breaker on it trips immediately. I have opened up the panel on top and disconnected the power coming in to make sure there is no short in the wire from the electrical panel. I see no visible signs or scorched wires in the oven panel. The fuse for the microwave is good and there is no short in the outlet for the microwave. Does anyone know what else I can test or look for to try and find what is causing the circuit breaker to trip?

SOURCE: No power and door locked after starting self cleaning cycle

Thermal fuse went out by door latch and thermal fuse on back of oven probably tripped too; once failed they need to be replaced. This is probably a job for the repairman as something caused fuse to go out in the first place; unless resolved it will recur. Please contact me if you need further help or leave feedback if appropriate as that is how I get paid. Thanks for letting me help you!

SOURCE: internal breaker trips

You will need to get an ammeter to see how many amps are being drawn by the motor. You can purchase an inexpensive meter at home depot or Radio Shack, The meter should be clamped around one of the wires from the motor. If the amps are more than the internal breaker, the motor is bad (even a new motor) if the amps are lower than the internal breaker, the breaker itself is your problem. You should also verify that you have the proper voltage motor and input to oven. Hope this helps

SOURCE: zanussi 360 just tripped and now keeps tripping

You will probably find that it is the oven element that needs replacing, located at rear of oven compartment behind rear panel.

SOURCE: My Belling E641 keeps tripping out. Now the trip

You evidently have an earth fault on the cooker i.e one of the heating elements has failed and the trip switch is operating to prevent you getting a shock.

Most likely it is one of the radiant rings that is at fault but it could also be an oven element.

There is no easy way to tell without checking with a multi-meter for earth continuity between each element and the cooker frame, you can do this with the power off and the meter set to resistance or continuity test.

There should be no reading between healthy elements and earth but a faulty element will normally show a reading when the probe touches the cooker frame.

SOURCE: DeLonghi EOF260 tripping the circuit breaker

It is probably an element that is causing the trouble, as it gets hotter, the insulation resistance breaks down, and if there is a weak spot or hot spot it causes the trip to operate.
I'm afraid it is a question of elmination, trying different functions, until you isolate the problem.

We set our wall oven for self-clean and received an error message after about 4 hours that told us to turn off the circuit breaker. We are unable to turn the circuit breaker back on again.


Hi,
If you cannot turn the breaker back on then it is no good...some breakers do take some very firm effort to get them to come on...but the oven may have ruined the circuit breaker...

The clock works but the oven does not heat up


Hello George, welcome to fixya.

The symptoms you describe are a common occurrence when the hi-limit has tripped. This typically occur's following a self clean cycle. The display will indicate the oven is indeed "on" but it will not heat do to the circuit being interrupted by the hi-limit ( which is what it was designed to do ).

Fortunately if it is tripped, they are the manual reset type and are accessible behind the black grill/vent just above the door and just below the control panel next to the lock latch assembly. **Turn off the 40amp breaker at your service panel or sub-panel in the home before attempting any service...safety first**

With the power off, you should be able to remove the grill and push the red button in the center of the thermostat and that should fix your problem...if indeed the hi-limit is tripped you`ll know immediately because you`ll feel it click as you push it down. It will look like the image below...52bc5ab.jpg

Let me know if I can assist you further. If this solves your problem please rate the solution accordingly, if not let me know and I`ll try to guide you through other possible scenario`s.

Thanks for visiting "fixya" and good luck.

Oven door remains locked after self-cleaning


Hi,
Cycling the power off and then on again will sometimes reset it...often you will have to call the customer service number to get the steps to take to unlock that...

Thermador SC302T clicking noise, locked door after power outage


iodine, open the upper oven, look thru the grill below the control panel on the right side and there is your model number. The issue here is that when the power came back on the oven run thru a test and your lower lock motor has failed. It will need to be replaced. Yes the only way to stop this is to shut off the breaker.

Whirlpool RBS305PDQ11. After self-clean, oven won't heat up.


This seems to be a common problem with these ovens. The oven got too hot and the tco (Thermo cut off)tripped. This will have to be replaced. It is located behind the control board.

Thermador Oven won't heat after running self-cleaning cycle


SOunds like you need to reset the oven high limit switch. It should be located behind the grille obave the oven opening and below the control panel. There should be about 4-6 screws you need to take out to remove the grille to gain access. Turn the power of to the oven at the circuit breaker, then rech in with a screwdriver and push down on the little red button in the center of the hig limit until it clicks. the high limit should be about as big around as a quarter and have a wire going into one side and out the other. If this keeps tripping, you may have a bad cooling fan. When you run a self clean it should also run a fan to cool the components. You should be able to feel a breeze coming out of the bottom of the oven when the cooling fan (not the convection fan ) is running. If this fan doesnt run, it will trip that switch. Hope this helps!
