Open Question

Oven slow to heat up

The JennAir gas stove takes a long time to heat up in either convet or normal bake mode. What normally would take a few minutes to reach 300 degrees now takes 30 minutes and sometimes does reach the set temperature. There seems to be enough gas presure to work the gas top range and other gas appliences in the house. Any suggestions.

Thanks

Richard, sounds like you did all the pretests. You'll need a new display panel. When you work on it, be sure to cut the power.

SOURCE: Possible Control board problem

You may not necessarily need a new control panel. Sometimes the oven temperature can be calibrated. Look in your owner's manual (if you have one) for calibration instructions. This will usually take care of the problem. If not, you may have to replace the oven sensor located inside the oven in the upper right or left hand corner of the back wall. Good luck.

SOURCE: Re: GE Electric Range JBP67BD1WH Baking Element Problem

Before you replace the range, I'd try replacing the oven temp sensor (part number WB21T10007 ) which is rather inexpensive. If I were able to get my hands on your range I'd first test to see if the control is sending 240 volts to the bake element. We know there is 240 to the range because the burners and broiler work, but is the control sending the full 240 to the bake element ? The only way for you to know this is to use a meter and test the voltage across the terminals of the bake element when in bake. Of course you should also test the bake element with power off and at least one terminal disconnected to see if you have about 20 ohms resistance across the terminals and no resistance from a terminal to the frame of the range. If not, you may need a new bake element (part number
WB44T10010 )
Let me know if I can be of further assistance. Thanks for using fixya.
If this helps, a fixya rating would be appreciated. Thanks.

SOURCE: oven slow to heat

An extremely common problem on these models is a weak silicon carbide ignitor. You may be able to see the ignitor glowing, but that is not an indicator of it being functional or not. When the ignitor gets "weak" over time, it will not create enough amperage in the circuit for the gas valve to open. You can test this using an amprobe around one of the ignitor leads and looking for at least 2.9 amps, but years of working on these appliances has shown that if you are getting the glow from the ignition but the oven is often slow to come on, you need a new ignitor. Do-it-yourselfers often mistakenly replace the oven valve or the oven temp sensor, figuring the ignitor must be good because they can see it glowing.
Replace the ignitor and your oven will work great again.

could be a bad bake element, bad temperature sensor, or control board problem

what does the oven readout display for temperature? if the readout agrees with the actual oven temperature ... it is probably the element

if the oven readout displays a much higher temperature it may be the temperature sensor (the probe in the oven cavity) or the control board

the temperature sensor can be tested by measuring its resistance with power off and unplugged from the control board, should be about 1100 ohms at 75F

If the sensor is good, then it is probably the control board ... in which case we can repair it for you at www.fixyourboard.com

Oven slow to heat , oven burner goes on and off a lot, oven igniter glows....broiler works fine


Hello. I need the make/model number to help you accurately. It sounds like the bake ignitor is worn out and not consistently igniting the gas. How old is the unit? If it has more than a few years on it, the ignitor can wear--it might glow, but not enough to ignite gas. Remove the racks.Remove the bottom cover of the oven(usually there are 2 screws, right and left side at the rear, inside the oven. There usually will be a heavy steel flame shield held on by a single nut underneath the cover. Remove this shield. This will expose the ignitor(called a glow bar). One of the classic symptoms of a worn bar is that the center of the glow material will turn bright orange but not the rest of the resistive material. Also, you can test the viability of the bar using a meter. Normal amp draw on either of the 2 wires connected to it should have approximately 4 amps. Use a clamp-on voltage/ohm meter set to amps. Under normal conditions, the electric gas valve senses the current draw and will open, letting in gas to ignite. From activating "bake" to ignition *usually* takes 20 to 30 seconds. If you find yours is worn, HANDLE THE REPLACEMENT GENTLY. Don't knock it, drop it, or touch the resistive material. It is FRAGILE AND BREAKS EASILY(ask me how I know this!)The mount screws(usually 2) can become seized due to heat. Take your time removing them. Another symptom of a worn ignitor can be the "WHOOF" sound of too much gas building up in the oven prior to ignition. I've seen oven doors knocked open by too much gas saturation suddenly igniting from a slow glow bar. I hope I helped you!

Whirpool gas range - propane gas not sure oven is working right


First, the flame should be blue and without much visible yellow. You need to give the gas tube a good cleaning to get out any soot buildup and any partial obstuctions that might be causing the problem. Since you started with a yellow flame and soot, you need to get the burner tubes clean to see if you have resolved the problem after adjusting the regulator and burner valve(s).

You might need to install a different regulator to match the pressure of your gas supply source, as regulators have a specific working range of inlet (supply gas pressure) that they can operate properly at to "regulate" the supply pressure to the stove's needed pressure.

Check your manual and the installation guide to verify what the gas inlet pressure requirements are and check with your gas supplier to see what they are providing you.

To your 2nd question, yes, the gas will cycle on and off when you are using the oven, since the thermostat will call for more heat when needed and shut off the gas/flame once the temperature you set the control at, has been reached. The cycling is a result of the oven trying to maintain the desired temperature for baking.

One reason that you can smell gas when the oven is being used, is because all gas ovens have a surface vent to allow excess heat to escape from the oven compartment, however you should not be smelling raw gas (actually you're smelling the "rotten egg" additive that's put in the gas) all the time, since when the oven is turned on, a small electric ignitor is heated up VERY HOT glowing bright orange inside the oven compartment. Once it's hot enough a sensor opens the gas valve and lets gas into the burner tube to be ignited instantly by the VERY HOT ignitor. It is rare to smell raw gas with this system, but sometimes you'll get a stronger "rotten egg" smell at different times due to the gas company and their system, etc.

As to the gas smell, you should NOT be smelling gas every time the oven cycles on when baking, as a normal ongoing occurrence. During the first few uses, it is normal to smell some gas, but this should go away after a couple of uses. If it doesn't, you should look to make sure the regulator and oven controls are PROPERLY configured and set - Since you've already fiddled with these, it's probably a good idea to have someone from your gas company (or a gas appliance tech) come out and do this. Improper settings can cause some serious problems.

Hope this helps!

This is your igniting bar it regulates the gas and the start up of the oven. It is at the bottom of the inside of your stove and if you take off the cover you will see it. It is rectangular and when you try to start up the oven it glows orange. Change this and it should work fine.

Oven will not heat


ok few things sound like the gas valve may be turned off what i mean about turned off is at the gas valve contro;l normally installed under the stove on the left side of the valve tere is a verry small lever that serve as a shut of vave i have seen those lever in plastic normally red it may have sticked it self close or fallen out check on the floor if you do not see any small parts another thing check for fuse also there is a solenoid valvve that possibly not opening up one more thing does your stove connect to a normall 120 volt plug or does is connect to your 220 volt electric stove plug with a adapter if so check your breakers thanks gilles_dumais@hotmail.com

It sounds like you have some condensation in your gas lines.
The fact that it only does this when preheating kind of reinforces that suspicion.

By the time the oven has reached temperature setting, the bit of moisture has been either blown or baked out of the system.

Steam clouding the window would confirm this or if don't have one, you clould put a shiny pot into the oven and check it for condensation after a few minutes while the popping is taking place.

Preheat taking long time


If your oven has the hidden bake element then it is probably working properly. A standard oven with an exposed bake element will usually take about 12-15 minutes to preheat. The hidden element models take a little longer but they usually heat a little more evenly.
Post back if you have any more questions.
