dacor oven heat quits before it reaches set tenp
Set over for 400 and quits at 280. Reset it to 400 and it quits at 300
We really need a model number to even determine if this is a gas or electric oven as Dacor makes both. That will help us eliminate half of these possible causes.
Most Frequent Causes for Oven temperature not accurate
When the bake element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the heating element has burned out, it will be visibly damaged. Inspect the heating element for holes or blisters. To determine if the bake element has burned out, use a multimeter to test the element for continuity. If the bake element does not have continuity, replace it.
The igniter draws electrical current through the gas valve to open it. As the igniter weakens over time, it takes longer to open the gas valve. As a result, the oven temperature will drop too low before the burner reignites. The oven temperature should not drop more than 40 degrees Fahrenheit before the igniter relights the burner.
The broil element may have burned out. When the broil element is heating properly, it glows red hot. If the element does not glow red, this indicates that the element is not heating. Often, if the element has burned out, it will be visibly damaged. Inspect the broil element for holes or blisters. To determine if the broil element has burned out, use a multimeter to test the element for continuity. If the broil element does not have continuity, replace it.
Temperature Control Thermostat
The temperature control thermostat monitors the temperature inside the oven and cycles on the heat when the oven temperature gets too low. If the temperature control thermostat is not calibrated correctly, it won't cycle on the heat at the proper time. As a result, the oven temperature might be too high or too low. Due to its complexity, the thermostat is very difficult to test.
The oven sensor works in conjunction with the oven control board to regulate the temperature. The sensor regulates the oven temperature by varying its resistance to electrical current as the oven temperature varies. As the oven temperature rises, the oven sensor creates greater resistance. If the sensor gives the wrong amount of resistance, the oven may not bake evenly. On some models, you can recalibrate the oven control up to 35 degrees Fahrenheit higher or lower. Refer to your owner’s manual for instructions on how to recalibrate the oven control.
Oven Control Board
The oven control board works in conjunction with the oven sensor to regulate the temperature. The sensor regulates the oven temperature by varying its resistance to electrical current as the oven temperature varies. As the oven temperature rises, the oven sensor creates greater resistance. If the sensor gives the wrong amount of resistance, the oven may not bake evenly. Or if the oven control board does not read the sensor resistance correctly, the oven temperature may be inaccurate. On some models, you can recalibrate the oven control up to 35 degrees Fahrenheit higher or lower. Refer to your owner’s manual for instructions on how to recalibrate the oven control.
In a convection oven, the convection element works with the other heating elements to heat the air circulating inside the oven. If the convection element is burned out, the oven won’t heat evenly. To determine if the convection element is burned out, use a multimeter to test the element for continuity. If the convection element does not have continuity, replace it.
In a convection oven, the convection motor drives the convection fan to circulate the air inside the oven. If the convection fan isn't circulating the air, the oven won't bake evenly. Try turning the convection fan blade by hand. If the blade is hard to turn, this may indicate that the motor bearings are worn. If the motor bearings are worn, you will have to replace the convection motor. To determine if the motor is defective, use a multimeter to test it for continuity. If the motor does not have continuity, replace it.
Make sure the oven temperature is calibrated. You can find instructions on the net. Be also aware that the oven relay board can be difficult to get repaired. We had a terrible time getting someone to repair the board in our Dacor. The company did not make that board anymore and they were of very little help in getting me to a place who could do a board level repair. I honestly thought I was going to have to scrap the $2200 oven, just because of the inability to get the board repaired or even replaced? The company does not do it, and the referral they provided did not do it, they did the newer boards. Mind you, our Dacor oven is only about 10 years old. I finally found a company that would do it. Relay boards are in EVERYTHING. They 'relay' the commands from a touch panel and get a product to do something, like get to a temperature, switch on, etc. There are a few companies that seem to specialize in repairing these boards and the repair is cheaper than a replacement.
Sorry to hear about your board. Check your oven paperwork and look on the schematic for the drawing for the relay board and note the part number. I actually had the board repaired by a company I found on E-bay. If you Google "control board repair' you will find several companies that now repair them. They are in nearly all home appliances: dishwashers, refrigerators, ovens, some cook tops. Consequently, there are several companies servicing them so the consumer can cut the costs of replacing them. Look at a couple of sites and type in the make and model of the appliance and you can get the repair charges. I took mine out myself, it's not too hard. Take a couple of pictures. Pay particular attention of the little plugs and mark them with numbers on a piece of tape. Send the board in and get it repaired. A couple of places even give you a 2 year warranty. My problem was enhanced by the fact the the board I had, the 72720, about 10 1/2 years old, was 'obsolete' and several places would not fix it. I checked with this company on e-bay and they would be able to fix it. (Hold on to your hat: $86.00!). Core-Centric is the largest servicer, but at the time, they could not fix my board. At the time of my repair, Dacor had no boards, not even a supplier. This has changed, and they now have boards, but they are expensive. I put in a new updated board a couple of years later and had it done by a Dacor service agent. Do you use the 'self clean' feature? We were told never to use that. Heat's up too much and can damage the board. Also, let the oven cool down with the door closed, so the heat does not come out and heat the front control panel. The service company will need both, at least in my experience. Then the oven will have to be re-calibrated. Ours was off from the factory (when we bought it).
Go to E-bay and search for DACOR relay board repair (your part number). You will find several repair places.
Regarding the Dacor line: I have heard that the company was bought by Samsung. I guess we consumers should ALWAYS buy an extended warranty. Next time, I won't spend so much on a 'premium' brand. According to all the research I did, nearly EVERY brand has issues.
If its an electric i can say this is a thermal fuse problem. Usually the one on top of the oven basket. These are round fuses and can be checked by connecting a continuity tester on it and placing it on the stove. Have a thermostat on there too. The heat should match the rating and it will then disconnect the current when it reaches its designed temperature. These are cheap to replace and will be the best bet
