If the fan is working, but there is no heat, it means the element is faulty.
Fit a new element and it should be o/k.
Plz rate my solution.
Thanks.

I have a New World Double oven, dual fuel range cooker - NW 90DFD0 The main oven isn't heating up.


Hello Ally;

My name is Peter. I am a retired field service appliance technician.

You may not have a problem. Normally your oven will rise about 40 degrees F. above the set temperature and then shut down, until the oven temperature falls 40 degrees F. below the set temperature, then the oven turns back on.

Your oven temperature is controlled by you oven thermocouple.

You also have a high temperature limit switch, which turns the fan on when you go too far above the set temperature to vent the oven. This may be bad.

Why does my Oven not heat up ?


Did you check to see if the element is receiving power? Is element open?

Temp not accurate


Why is the oven temperature incorrect?

The oven temperature control is usually controlled by a thermostat that uses a capillary and liquid filled bulb. When the bulb's liquid gets heated up, it expands and puts pressure on a diaphragm which opens and closes a switch that controls the gas to the burner. Just set the dial to what you need the temperature to be. Over time, it is possible for your thermostat to lose its calibration. Sometimes, the thermostat sensing bulb comes loose from the holder. If it is out of place, the thermostat may be getting faulty readings. If this is the problem, re-aligning the bulb properly will take care of this problem.

Digital display models use a sensor to control temperature. If this is faulty, replace it. Other ovens use a mechanical system to control the temperature.

On many models, you can adjust your oven thermostat using a small screwdriver. The adjusting screw is located on the thermostat valve stem. Remove the knob and you'll see the screw underneath it. You want to turn the oven on and run it through at least two cycles while watching a calibrating thermometer in the oven for high and low temperatures. Adjust the screw as necessary to fine tune the temperature.

Some models don't have an adjustable thermostat, and you will have to replace the thermostat if you want to resolve the problem.
The oven sensor: works with the oven control board to regulate the oven temperature. If there is an oven temperature problem, this sensor might be defective. The sensor can be tested by using an ohm meter. As temperature rises, the resistance measurement also rises. The manufacturer of the oven sensor determines the correct resistance, Oven temperature problems can be caused by other things, but this is one of the common causes.
Beware on some models now most of these ovens they are electronic and they are integrated into the control itself
some different sensor ohm readings at room temp. approx 16 ohms at room temperature and at 350?F it is 29~33 ohms.

When on fan symbol only and with a temperature set manually, the oven will not heat. The bottom and top heating elements will heat up seperately on other settings


My oven is DOP705X. It had the same problem on two occasions. First time it was simply the fan element. Second time I thought it was the element so replaced it again, but no fix. Turns out it was the relay for the fan element, it had got sooty and black. A quick clean of the contacts with emery paper and it was all working again. If the relay needs replacing, a new one is £2.88 from RS Components, but replacing it will require a spot of skillful soldering.

Circulating oven function not heating up properly and fan not going round


Oven comes on and off intermittently or heats very little:

If the timer feature is activating and you have not touched the timer button at all, this would have to be a failed Electronic Oven Control. The timer button is either shorting at times or closing on its own from heat or moisture. The Electronic Oven Control would need to be replaced to repair the problem.

Or Why does it take the oven so long to bake?
When the food is taking way too long to bake, it's probably a weak bake ignitor. Replacing the ignitor usually fixes this problem, but you probably want to verify that the ignitor is the problem before replacing it.

Sometimes the oven thermostat or oven sensor can be calibrated wrong, or it may be faulty. If your particular range has an oven that uses an electronic thermostat, and the oven temperature is off by tens of degrees, you probably have to replace it.
On most units that have a mechanical thermostat, you can actually remove the thermostat knob, and adjust the knob to more accurately represent the actual setting of the thermostat. On many models, there's a screw on the back of the knob with a small calibration plate or ring. You can loosen this screw and adjust the calibration plate. Remember to tighten the screw again. If yours isn't adjustable, and the temperature is off by a large amount, you should just replace the thermostat.
Or Oven safety valve needs to be checked with multi meter ohms / voltage

ALSO Test the Burner Heating Element
The stove's burner heating element is a coil of metal sheathed in an insulator. Electrical current travels through the element. Resistance to the passing of electrical current causes the element to heat up. A precise temperature cannot be set for a burner, instead it is turned on and off repeatedly by the control to the achieve an average temperature. When it is set to a low temperature, the element is cycled on and off more frequently. For high temperatures, the heating element is energized longer with fewer on and off cycles. Some burners have two elements, with the second only being used only for high heat settings.
Before testing the heating element, unplug the appliance or shut off the power at the fusebox or breaker panel to avoid an electrical shock hazard.
When a burner does not heat at all, or only heats up to a lower than expected temperature, the problem is likely to be with the heating element, the temperature control switch, or the wiring. If it only heats at the highest temperature, the problem is with the control or an electrical short, not the burner. If the burner works only intermittently, the problem is likely in the wiring or connectors. To test the heating element, try the following steps.
First, disconnect the heating element from the stovetop. In most cases, this is done by lifting up the burner on the side opposite of the terminals (the part of the burner that disappears under the stovetop). Remove the decorative ring.
Inspect the style of connection. If the burner element has visible blades that fit into the receptacle block, pinch the block with one hand, and pull the heating element free with your other hand. If the terminal block clamps over the element, the housing must be removed and the burner wires disconnected. Unsnap the metal piece or remove the screw that secures the receptacle block and then disconnect the element.
Inspect the heating element. If you find bubbles, warping, or damage to the insulation sheath, the burner must be replaced. If the terminals are dirty or corroded, this can cause poor temperature control, intermittent problems or complete failure to heat. Clean the terminals with steel wool or very fine sand paper to restore good conductivity.
Test the resistance of the heating element using amulti meter. Set the multi meter to the ohms setting X1 and touch one probe to each of the terminals. A normal reading is typically somewhere between 20 and 120 ohms. The exact reading differs by manufacturer and mode. If the meter reads infinite resistance or the other extreme of the scale, zero resistance, then the element is damaged and should be replaced. If the measured resistance differs significantly from the expected range, the element is probably bad, but if possible, determine from the manufacturer what the actual resistance should be.
To test for a grounded or shorted element, touch one probe to the surface of the burner and the other probe to each terminal in turn. If you get continuity at any time, the heating element is defective and should be replaced.

Hi Maurice.

Circulating is Fan Assisted mode. In this mode the fan kicks in when temperature is reached and runs all the time.

Here an extract from manual.

There is no preheat unless you set temperature. That is why you get the fan from start.
