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.

De Dietrich oven not working


1.Even a bad relay door switch will hinder your oven from operating.

If your oven has internal fuses, a wiring or component problem could have caused a fuse to blow. A blown fuse is an indication that a component has shorted or failed, and the problem will need to be corrected. Most ovens that use fuses will have an indication of the circuits that are affected by a particular fuse. If an oven fuse has blown, then you should inspect the oven element and the associated wiring to determine the cause before replacing the fuse.

THINGS TO CHECK:

the broil element
is the heating element that is found at the top of the oven and produces a very high heat for broiling. If the broil element isn't working, you should first do a visual inspection for signs that the element has blistered or separated. If the element appears normal then you can check for continuity with a multi-meter. Remove power from the appliance before performing this test. Remove the back panel and locate the terminals for the broil element and inspect the terminals and wires for signs of overheating or damage.

If there is no continuity then the element will need to be replaced. If the wires are damaged then they will need to be repaired. If the element is ok then you will need to check the broil circuit to determine the cause. This involves live voltage checks and should only be performed by qualified persons. Components to check include fuses, if the range is equipped, and oven control thermostat or electronic control. Depending on the manufacturer of the element, you will normally read between 19 ohms and 115 ohms


The bake element
is the heating element that is found at the bottom of the oven. Most electric ovens use both the bake element and the broil element in a bake cycle, with the bake element performing 90% of the heating. If the bake element isn't working, the oven may not heat. To help determine if the bake element is defective you should first do a visual check. If the element is blistered or separated then it should be replaced. If the element appears to look normal, then turn the oven on to a bake function for a minute and then turn it off.

Check the element for signs of heating and if it is still cold then it may be defective. Disconnect the power and then remove the back panel. First check the wires as they may have become loose or corroded. If the element appears to be fine visually, test it for continuity with a multi-meter. ( by placing the each of the meter prongs on each end of the heater element connectors) If the element is burned or no longer has continuity, it will need to be replaced. Depending on the manufacturer of the element, you will normally read between 19 ohms and 115 ohms

The oven safety valve
(also called the gas valve) is the part that ensures that gas is not released until the igniter has reached the correct temperature needed to ignite the gas. While this part can fail, it is uncommon. If the hot surface igniter does not glow you should first verify that you have voltage to the circuit. This is a live voltage check and should be performed by a qualified person. If voltage is lost at the valve terminals then you should verify the continuity of the bi-metal in the valve using a multi-meter.

Is it possible to turn my Bosch oven in to 110 volt? Model number HBN58T650A Thanks


I did a search for this Bosch oven-
It sounds like the oven is not a conventional Resistance heating oven-
So it might be possible--

Do you have the manual for it?

I tried this web site: visit the website: www.bsh-group.com.
But It was not much help

Perhaps you can look in the phone book, and contact your local BOSCH appliance dealer, and have them look up the model in their Model catalogs?

Or-- You could pull the oven out, and check the wiring harness--
No doubt it will tell where the main cord comes in, -- if there is a hook up diagram for both 110 Volt,and 220 VAC connection diagrams-

When you get it out, tell us what you find-- maybe we can help further..

Grill wont stay on


Hi.

If this is an electric model, test the upper element.Before replacement the element can be tested removing it from the cavity and reading Ohms at the element terminals, with a multimeter set at Rx1. Disconnect power before removing the element.

If this is a gas oven, and the grill igniter is working, then test wiring to valve, valve solenoid and safety switch.

Regards.

BOTTOM ELEMENT DOES NOT WORK


If the top element is working, then it is either the element, the wiring harness , or the control board.

Since both elements are controlled through the same temperature probe, then the temp. probe should be OK.

The heating element must be removed and tested using a multimeter.

The part is tested disconnecting wiring from element contacts, setting a multimeter to read impedance at Rx1, and reading Ohms on element contact.
If the circuit is open (no continuity and infinite Ohms value), then the element has blown and must be replaced.


If the element has continuity, test the wiring harness, then replace wiring harness or control board.

All the test must be done by a trained repairer, strictly observing all health and safety rules.
