Question about Whirlpool RBS305PDS Electric Single Oven

1 Answer

Oven does not maintain temperature while cooking. Oven will come on and preheat as it should but then temperature drops while cooking and remains below preheat value. Every 15 minutes or so we set the temperature to 5 degrees higher and wait for the preheat just to keep it going. The self clean function and broil work OK. I have changed both the thermocouple and the control board. Oven temp will not go above 450F and heat seems really uneven.  This started happening suddenly about three weeks ago.

Is this a gas unit? If so you might have a weak oven igniter.

Why oven cools automatically after preheat

Others are having problems with this unit. Have the manufacturer support their product and fix it. It should be covered if it is new. Don't delay in hounding them. Time will expire and you will be left with an expensive ordeal.

Is it dangerest when your oven beeps f2

Typically an oven beeps when the interior temperature macthes the temperature where you set the dial. This is an audible signal to that fact and particularly helpful when you need to pre-heat the oven. For example it you want to cook something at 350 degrees, you set the dial at 350. When your oven reaches that temperature it beeps to let you know. Some cooking directions tell you to preheat your oven. In that case, when you set the dial to 350 and wait for the know you are safe to start your cooking process because the oven is now pre-heated to the temperature you set. If your recipe requires a pre-heated oven, and you don't wait for the beep, your taking a guess at what temperature you're cooking your food. Additionally, if you want to know what the internal temperature of oven is and your oven is simply turn you dial setting and listen for the beep. Again, if you set your oven at 350 and you want to know how hot your oven is... slowly turn the dial setting. If the oven beeps at 275 then that's how hot your oven has gotten. To let it finish heating to 350 just reset the dial and wait for the beep.

Oven temperature fluctuates.Oven heats to correct temp on preheat, but as the food cooks the temperature drops.


If your electric oven is taking too long to heat or just not heating up right, then check out this tip that will give more detail about your problem.

Oven Problems Electric Oven is Heating Slowly or Poorly


Nov 17, 2010 | Frigidaire Ovens

1 Answer

Oven sometimes doesn't heat up. Sometimes heats up to desired temp, then quits working. Sometimes doesn't even heat up at all. When preheated light comes on, thermometer in oven usually says about 100...

This sounds like a weak igniter, it would have to be a gas oven and the symtoms usually are: takes longer than normal to ignite the burner, may or may not smell gas in the oven, does not maintain set temperature, eventually won't heat at all. On gas ovens, a glo igniter is like a light bulb, the more you cook, the faster it wears out. Bottom line, needs to be replaced. Good luck.

5 yr old Jenn Air Electric oven won't maintain oven temperature

Technician just left our house with same issue. Jenn-Air had issued a technical bulletin as the temperature probe is mounted directly to the heating element, and measures the heat of the element, not the oven. Their fix is a revised temperature probe that goes at a 90 degree angle away from the heating element.

If your temperature is consistent, just off by a set amount of degrees, there is an adjustment you can make at the control panel.

Seems to be taking a long time to cook

To preheat oven just select the temp you intend to cook at and wait until the red light goes out,it is then preheated
Then you can put your food in and carrying on cooking.
Yes you do put it on fan symbol, but make sure it is on the right one , as some ovens have fan only as well as fan and heat.
Plz rate this solution.

Instruction manual

When you first use your Oven, the Oven will need to "settle". That is, it needs to burn off production residues and dust. The metal used in the Oven will also expand slightly when first used. You will experience some crackling and a strong smell. This is perfectly normal and we advice you anticipate this "settling" prior to use. Using an empty Oven, select Function 4 and set a temperature of 250°, allow the Oven to "settle" for hour, turn to function 3 and heat for a further 1/2 hour.
Multifunction Oven Function Selections

2. Defrost - This function activates the fan only, (no heat is used) to allow controlled and hygienic defrosting.
3. Conventional cooking - Normal or traditional cooking functions using the top and bottom elements. When using this function set the thermostat between 50 - 250°C. When the desired temperature is reached the yellow light will go out and then alternate between lit and unlit as the temperature is controlled.
4. Fan-Forced cooking - This selection is best for multilevel cooking as the heat generated by the central element is circulated around the Oven, creating an even heat environment. You will need to set the thermostat dial between 50-250°C for this function.
5. Center Griller - For best results set the thermostat to MAX. The door may remain closed or completely open.
6. Large Griller - For best results set the thermostat to MAX. The door may remain closed or completely open.
7. Fan Griller - This function combines the grill element with fan assistance and is used in conjunction with the thermostat. The Oven door must remain CLOSED during cooking. The thermostat dial should be set between 50-250°C for this function. 
8. Fan-assisted Baking or Patisserie Setting
 - Combines the concealed bottom element with fan assistance and is used in conjunction with the thermostat. The Oven door must remain CLOSED during cooking.


Advanced Oven Features

Cavity Cooling

The Oven has an advanced cavity cooling system. A cylindrical fan is mounted on the rear outside frame of the Oven. This fan assists the movement of air through the Oven cavity keeping it cool. In addition to reducing the temperature in the Oven cavity, the air is blown out around the Oven door handle which keeps the door handle cool. The cooling fan is activated when the Oven light or any cooking function is selected and will switch off after all Oven functions have been turned off.

Triple Reflective Door Glazing

Some Ovens have two levels of removable door glass. The two inner layers are removable and are made of a reflective glass which, in effect, reflects heat back into the Oven and results in a significant reduction in the outside door surface temperature. To clean the door glass, use a coin or large screwdriver to remove the screws. Wipe both sides of the inner, middle and outer glass. Wipe the sealing gasket. Don't forget to replace the rubber sealing gasket around the centre glass layer before replacing the glass. Ensure the narrow air gap lies between the inner and centre glass layers and the wider gap lies between the centre and outside glass layers. Tighten each screw gradually, one then the other until firm. Do not overtighten.

Wipe Clean Enamel (Extra Optional)
Some models have easyclean blue enamel paint throughout the internal cavity walls. Other models have baking trays and grill pans finished in the soft grey super tough "wipe clean" enamel. This enamel is less porous than conventional, so that food does not adhere as easily. Simply wipe clean with a soapy cloth or creme cleanser when cooking is finished. For baked on residue, use a smooth scraper or if necessary a non-caustic Oven cleaner.

Drop Down Grill Element (Extra Optional)
The removal of a single screw at the front of the upper grill element in some models allows the element to drop down so that cleaning of the roof of the Oven is made easy. On completion of cleaning, simply replace the grill element and secure with the screw, finger-tight.


The Electronic Timer

Normal Baking

Function 3: Normal Oven baking using heat from both the upper element and concealed lower element.

To bake, place the Oven rack in the appropriate position according to the type of food to be cooked. Turn the Function Selector to Position 3 and the thermostat knob to the correct temperature, and allow the Oven to fully preheat for best results.

Ideal for cooking casseroles, soufflés, roast, meats, and other items which require a slow method of cooking.


Fan Forced Baking

Function 4: Fan-forced central element cooking requires slightly different timing techniques than normal cooking. The fan draws the air in and over the central element which is positioned around the fan and then circulates it back around the Oven cavity. The even distributor of heat allows foods to rise and cook simultaneously regardless of shelf level. Lower cooking temperatures and in some cases less cooking time is another advantage of this feature.

Turn the Function Selector to Position 4 and turn the thermostat to the desired temperature. Pre heating takes much less time than a normal bake Oven.

Note: When cooking meats, for best results always preheat the Oven to ensure the meat surface is sealed to lock-in juices for a moist and tender result.

Fan forced cooking is ideal for multilevel cooking e.g.. patty cakes. Another advantage of fan forced cooking is that different types of food may be cooked simultaneously without mixing the aromas or flavours. When using the Oven in this way, ensure that all the foods require the same cooking temperature and check the finish times of each dish for best results.

Please note that fan-forced cooking is faster than conventional methods, so take care not to burn your food when you first start using this method.



Function 5 & 6: During grilling the door may remain closed or completely open.

This function offers the traditional grilling method necessary to achieve proper browning without overcooking the interior of the foods.

Position 5 activates the centre section of the upper grill element only, which is ideal for browning smaller portions or thinner cuts of meat.

Position 6 activates the entire upper element for the grilling of large quantities or thick cuts of meat.

Allow the griller to pre-heat for approx. 2 minutes before sliding the tray into position.

Place the grill tray into the roasting pan and arrange food according to the function you have selected, either in the centre of the tray or spread across the full width of the tray. Position the tray at the correct grilling level and turn the thermostat control to MAX for best results.

As the temperature is set to MAX you may need to adjust your grilling shelf height to suit the desired cooking result. If the tray is too close to the element, the food will be exposed to the full effect of the element and may burn and create smoke.

Amana Convection oven not controlling temp

I have just checked the baking guide in the manual and have found that it may not be us after all. (Maybe this is why they telll us to read the whole manual. Well, I never have) According to the cooking time for Baking, the range is very extensive. For example, an angel cake at 350 could take from 28-50 minutes, buscuits at 375-400 could take 8-16 minutes, layer cakes at 350-375 could take 25-40 minutes, pound cakes at 325-350 could take 45-70 minutes and fresh pies at 400-450 could take 35-60 minutes. Basically, the baking directions on the box means absolutely nothing to use Amana oven owners. We have no choice but to cook our food or baked goods until they are cooked, whenever that may be. :) Linda
