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.

SOURCE: 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.

Double check each connector to be sure it is installed (aligned on pins) properly. Also check wiring diagram for a safety limit thermal switch. If it has one, push to reset it.

Oven takes forever to heat up - its a thermador double oven - me272


Hello- Check these things first-  Door seals tend to get stiff over time. This is normal. Door hinges can become loose or get bent a bit, causing door to not close tight. This little gap can allow heat to escape, causing extended pre-heat times and frequent cycling of elements. If door doesn't seem to pull shut tightly- hinges will need to be replaced. If oven appears to operate normally otherwise, this should solve problem.  Let me know if the info helps- have more if needed- Thanks  - Ed

We've had the same problem. I contacted a local sales room and they contacted their rep who promptly mailed the replacement parts I requested (I'd looked up the part numbers already). Now I'm waiting to find someone who will reasonably do the work.
