Question about Kitchen Ranges

2 Answers

I have a Bosch oven model HBN58066OB. It was used in an exhibition and de-commisioned. The element wires were disconnected for safety reasons and then re-connected. I think the wires are connected incorectly because although the LED display and programmer works none of the elements work. It is not in demo mode. Is there a wiring diagram available?

Q - The microwave display counts down and the inside light is on, but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.

HI
Step 1: If the oven element doesn't work, first check to see if the range is receiving power. Don't overlook the fusing system inside the range.

Step 2: If the range is receiving power, set the timer on the range to the MANUAL position.

Step 3: If the element still doesn't heat, turn off the power to the range and test it with a VOM set to the RX1 scale. 

Step 4: Remove the screws or plugs that connect the element to the power. Remove the retaining shield, which is usually held by two screws, and remove the element from the brackets that hold it in the oven. The element is usually held in these brackets by screws.

Step 5: Clip the probes of the VOM to each element terminal. If the element is in working order, the meter will read from 15 to 30 ohms. If the meter reads higher than 30 ohms, the element is faulty and should be replaced. If the element tests all right but doesn't work, the problem may be at the terminals. Make sure the terminals are clean and tight at the element connections.

Oven and broiler elements cannot be tested without a VOM. If you don't have a VOM, take the element to a professional service person for testing. The problem is usually a malfunctioning element; however, you aren't risking much by replacing the element without a professional test.

Magic Chef cgr3765adc, oven will not turn off. If the unit is plugged in the oven ignites and would continue heating unless disconnected from electricity.


follow this test and fix it. God bless you

Bake Element

If the oven won't turn on, check the bake element. The bake element is a black tube near the bottom of the oven about as thick as a pencil. When it is operating normally, the bake element will glow red hot. If the oven won't turn on the bake element may have burned out. It is often obvious to see where the bake element has shorted out because there will be a hole or break in the element. If the bake element has burnt out or shorted it should be replaced.





Oven Igniter

Even though the oven igniter may be glowing, it may be too weak to allow the gas valve to open. If the oven won't turn on and the oven igniter glows for more than 90 seconds without igniting the gas flame, the oven igniter should be replaced. This is the most common part that fails when the oven won't turn on.




Broil Element

If the oven won't turn on, check the broil element. The broil element is a black tube near the top of the oven about as thick as a pencil. When it is operating normally, the broil element will glow red hot. If the oven won't turn on the broil element may have burned out and caused something else to short out. It is often obvious to see where the broil element has burned out because there will be a hole in the element or blisters on the outside of the element. Test the broil element using an Ohm meter. If it has continuity it's OK. If not, it should be replaced.





Incoming Power Problem

Although not as common, if the oven won't turn on it is possible that the appliance is not receiving proper voltage. Electric ovens require 220 volts of alternating current. If for some reason the appliance is receiving significantly less, the oven won't turn on. Check for proper voltage using a volt meter at the socket where the appliance plugs in.


Oven Control Board

The oven control board has a set of relays that turn on and off power to the bake and broil circuits according to the customer settings and sensor input. If the oven won't turn on the problem is usually with the heating components. However, if the oven control board is bad, it might not send voltage to the heating components. To determine why the oven won't turn on, first test the simpler components in the circuit. The oven control board usually can't be tested and will have to be replaced if it is defective.





Thermal Fuse

Although not as common, if the oven won't turn on the thermal fuse may have blown. The thermal fuse is designed to protect the appliance and help to prevent a fire. If the oven gets too hot, this fuse trips. The thermal fuse is not resettable and will have to be replaced. It can be checked for continuity. If it has continuity, it's OK. Not all ovens have a thermal fuse.






Relay Board

If the oven won't turn on and the appliance is equipped with an oven relay board, one of the relays on the board may have failed. Normally the oven relays are located on the main clock control board and not on a separate oven relay board. If the oven won't turn on it is more likely that the cause is one of the more common problems listed for the model. If the other, more common problems have been checked and Your oven has a relay board, it may need to be replaced. Oven relay boards are not repairable.





Oven Thermostat

If the oven won't turn on, the oven thermostat might be defective. Although this is not as common as other components, the oven thermostat sometimes fails completely and does not allow current to pass through. After checking other, more common components, consider replacing the oven thermostat.





Heat Selector Switch

If the oven won't turn on, be sure the heat selector switch is set to the right position. The heat selector switch completes the circuit to either send voltage to the bake or broil circuit. If the oven won't turn on, the heat selector switch might also be defective, although this is not very common. The heat selector switch is not repairable, if it is defective it will need to be replaced.





Oven Safety Valve

The oven safety valve works with the oven igniter to provide gas to the burner. If the oven won't turn on it is possible that the oven safety valve is defective. However, this is very rare. Most often, the oven igniter is too weak to allow the oven safety valve to open. If the oven won't turn on, check the igniter first.





Oven Valve and Pressure Regulator

If the gas oven won't turn on the oven valve and pressure regulator might be at fault. This is not common. Very often people misdiagnose a defective oven valve and pressure regulator when the oven won't turn on However, this is almost never the cause. Look at other, more common components before replacing these.

I replaced the the convection heating element on a Bosch HBL 455 AUC electric oven. The power trips when I turn on the upper oven (where the repair was made). The lower oven clock and lights are working...


sounds like a short in one of the wires has a short in it where it was replaced. That would explain the power tripping. Search for any rips in the wire or where the wiring might come in contact with a sharp piece of metal.

Bosch HBN 70 Fan oven will not heat up to temperature, fan and light are working just no heat


99% of the time the problem will be a faulty element or burnt off wire at the element terminal. Best way is to pull the back cover off the oven and check the terminal connections. If these are okay put a set of test lamps across the terminals and you should have 240 volts. If you have 240 volts this tells you that the wiring is okay and the element is faulty. When you turn the oven setting to fan forced selection the power is delivered to the fan forced fan motor and the oven element at the same time. I am not familiar with this exact oven but most fan forced ovens have two fans. There is the fan at the back of the oven that comes on with the oven element and then the extractor fan in the cavity of the oven, which you cannot see but can hear. I trust you are talking about the fan forced oven fan which is generally at the back of the oven.

The bottom element in my Kenmore oven just got red


Yes. Unplug the range, remove the screws, holding the element, remove element, disconnect wires on the ends of the element. Installation is the same in reverse. Complete model number is needed for the part# of the element

We have a digital display on our Frigidaire stove it is not working and nor is the oven. The elements are fine. Any suggestions please?


Hi.

A technician should read voltage to the electronic oven control board, to test the EOC in full. For safety reasons testing hot wires is an operation that must be done by a repairman.

If there is no power to electronic control, then the wiring harness must be replaced.

If the oven control display is blank I would exclude that the problem is being caused by faulty element, faulty temperature probe, or defective door latch, all this faults do not cause the display and controls being non-responsive.

Most ovens have display, control board and pads as separate parts, in that case the connectors between parts in the control assembly must be tested.

Parts and diagrams for most models are available here.

Regards.

Ginko.

The top burners work fine and the oven does not appear to have any problems but the heat elements (bake & broil) suddenly quit working.


Usually a safety thermostat, but it can also be wiring, a control board, or a dlb relay. Call Kitchen Aid warrantee service on this, as some of the electonics have a longer warrantee on them. Good Luck, Appliance Specialists.

Cooking element


You do not list a full model number. Typically a JBP78_____ uses a WB44X10013 bake element. Disconnect power to range. Take out two 1/4 inch hex head screws holding element in at back of oven. Pull element out a few inches into oven. Disconnect wires. Reverse to install. Not too hard if it is an exposed element. A bit more involved on ranges with "hidden" bake elements (which are under the floor of the oven).
