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.

Need manual for self cleaning, please?


Hello Mary;

You can get a user manual at the following website.

Locate your oven model number. It is located on a label either on the face of the oven when you open the door or on the side of the door. Put he model number into the website and you will get diagrams, component part numbers and manuals.

http://www.searspastsdirect.com/

I suspect the user manual is not going to help you. Tell me the model number and what is going on.

Manufacturers offer the self cleaning feature on ovens because customers like this feature and the ovens sell. Yet, the manufacturers engineers have not been able to provide a design that will protect all of the components from self cleaning temperature of 900-1,000 degree F.

When you go into the self cleaning model, the door will lock when you reach 500-550 Degree F. The oven temperature will raise to 900-1,000 degrees F. The oven door will not open until the oven temperature drops to 500 degree F after the self cleaning cycle is completed.

Now, You have a high temperature limit switch in your oven. If this switch fails, you will loose power to your control board and you will not be able to open the oven door.

If you have never used your self cleaning feature, the high temperature limit switch may have failed.

Do to the problems involved with the self cleaning feature, knocking out the control board from heat, additional heating element failure, and other components; It is in my professional recommendation as well as my fellow technicians not to use the self cleaning feature. If you do, do not run it for more than 1 hour instead for the manual 4 hours.

Periodicly I won'y be able to get the grill temp to over 200 degrees. sometimes it is ok and can reach as high as 500 degrees other times it will just not generate enough heat to grill.This is a five...


zonfish - if you're tuning the gas tank off at each use, as you should. The problem lies in your grill's gas regulator, but it also is not a big deal and is easily solved.

Whenever, you open the tank valve, do it VERY, VERY, SLOWLY (Slow Motion, slow), until it is fully open. Then light the burners.

What happens is this, LP Gas Grill Tanks are now equipped with an Overfill Protection Device ("OPD"). And often time, when you turn the valve on like you would normally do, the OPD Valve sends a hot load of gas to your grill's regulator and partially locks it up or locks up entirely. Therefore, the burners are not getting enough gas to heat the unit up to 500 degrees. Opening the valve very, very, slowly, overcomes this problem.

I hope this helped you and Happy Grilling.

When I preheat the oven it takes an hour to reach 200 degrees. Is this normal? I am sure it was a lot quicker than this.


An hour to go from room temperature to 200 degrees F (or even C for that matter) is unacceptable.

There is a problem with either a control, sensor or heating element. You should have this oven serviced to restore it to proper working order.

My Magic Chef gas oven thermostat is not working properly. At 400 degrees it only heats to 200 degrees and at 500 degrees it only heats to 300 degrees. Do I need to replace it or can I calibrate it?


ther is a temp sensor that goes from the control valve to the oven,this may be the problem, make sure sensor probe is tight where it screws into the gas valve and other end is not just hanging in the oven, it attaches to the top of oven,if it's where it's supose to be, I'd change that first

Oven temperature does not get hot enough.


Hi, It sounds like the ignitor might be getting weak and opening the gas valve conditantly. Try setting a temperature and watch to see the ignitor glow. The flame should ignite within 30-45 seconds. If the flame ignites to heat rith away, it should get up to temp before shutting down.
I hope this helps you. Please let me know if I can assist you further with this issue.

Thanks
Vic

15 yr-old GE electric oven takes over an hour to preheat to 450


After jiggling the lower burn element the oven heated up in the normal time. Perhaps a connection had come loose.

Oven slow to heat


In alot of ovens preheat will cause the both the broil and bake element to come on. You are most likely getting heat from the broil element. This means either the bake element is bad or the relay on the oven control is bad. If the element shows resistance with an ohm meter then replace the oven control board.
