Hi,

From what you are saying it seems as though you have an oven circuit/control board problem...

the board is not getting the proper power/voltage to the elements


Replace the control board ot get it working again...

I have a built in wall oven whirlpool gold mod.gbs309pvsoo controls turn on but no heat from element


Could be element could be Hi limit thermostat could be control. In that order. First step is turn breaker off and remove element to make sure the wires are still connected to back of element. Visually inspect element very good for burns or a white powder residue signally the element burned up. Next step is harder, need to remove the oven and take off back panel, there you will find the hi temp thermostat. Check for continuity, if none replace.

Maytag oven will not heat, no gas flow. Broiler works, clock and timer works.


Hi,

You may even see the orange "glow plug" (called a hot surface igniter) glowing orange and so assume that it's OK. Not necessarily!! You have to measure the current/amp drawn by the igniter and compare it to this repair sheet before you can say it's OK or not. The gas valve has a bi-metal that open when a certain amount of current flows through it to heat it up. The igniter is wired in series with the gas valve. As the igniter gets older or weaker, it's resistance increases to the point where not enough current is flowing to the gas valve bimetal to open it up. As a result, the gas valve never opens up. BTW, a common symptom of the early stages of this problem is erratic temperature control in the oven due to delayed firing of the bake burner while cooking.

The hot surface igniter will not come on - check igniter with a ohm meter, you should have continuity through the glow bar, the glow bar can also crack = new igniter time. The glow bar comes on but the main burner will not light - you should have an amp probe to check properly, but often this is a hot surface igniter problem. The hot surface igniter often looses it's ability to get hot enough to open the gas safety valve. The safety valve can fail, but most times it is just a bad hot surface igniter. The hot surface igniter can also quit part way through cooking , in other words the oven may cycle a couple of times and then it just sits there with the red glow from the igniter. See this service sheet for the proper way and amp readings for the hot surface igniter system. Hot surface igniters do weaken and will eventually generate less heat than they normally could. When this happens they can still allow marginally correct current to flow to the oven gas valve for it to open but not get quite hot enough to ignite the gas burner immediately. When this happens, gas released into the oven can sometimes build up to the point where when finally ignited, the amount of gas lit can cause a small explosion inside the oven or cause an odor of gas with out the oven working. Yes, your glow bar igniter can glow orange-red and still be bad!! How a common gas valve works - click here.

Tappan Oven 316246653. Preheating the Oven does not work. Bottom Heating Coil (if thats what its called) is not working. The Broiler Coil at the Top does work. Is it the bottom coil that needs replaced...


Usually when the element fails to heat up, It means its usually broke, cracked, or where they plug in gets brittle and breaks. Your best bet is to replace the bottom element.

This an old range with side by side ovens which work perfectly. the 4 burners slide out, all 4 elements will heat, but do not get to a high heat, is there a control which affects all of the elements ...


Hi and welcome to FixYa, I am Kelly.

This sounds like your missing 1/2 of your input power. Go to the main CB panel and cycle the Range CB to OFF by pressing it hard to off and then back on. Test your burners again.

Still have the problem? Start looking in the area of the house to oven power connection / terminal block in the back of the oven for signs of HOT / burned terminals.

Still have the problem... Last check is to check wiring in the main controls area.

Without your model number this a VERY generic response but when all burners present the same symptom it is usually input power or control related.

If you respond with a model number I wil see what I can find that may help you troubleshoot your Oven.

Thank for choosing FixYa,
Kelly

My old GE oven (JSP38G052BG) won't bake or broil. It start then stop after 1 or 2 minutes. The heating elements get worm. Can you help me please


Hello ediben11.

If your oven's bake or the broiler heating elements won't heat but the range burners still work;the clock may be set for a timed or self-cleaning cycle. So,make sure to check the clock buttons and the knobs are set properly.
*If your clock has a knob that says "push for manual" then push the knob in after that, try the baking and broiling elements again.

*If it still does not work properly, you may have a defect in the thermostat/selector switch/common wiring.

*If the oven does not have a separate bake or broil selector switch; then the thermostat is probably the problem. It is not easy to check the selector switch or thermostat for proper operation. If you suspect a problem in this area, call a qualified appliance repair technician.

Hope this helps.

Microwave not heating


In all likelihood the Magnetron, or Power Diode has failed, or perhaps even the Power Supply. You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Whirlpool Range RF315PXDW. Electric range. Top burners and oven will not turn on. Clock on top of stove and oven light turn on. Oven preheat timer operates but heating elements in oven do not turn on....


It sounds like you are missing part of your input voltage.

I would take a voltage reading at the receptacle and confirm you are reading 220-240VAC. Some homes have the 220 service receptacles wired up with two 120 volt breakers to make up your 220 service. If your home is configured this way, you may have one of the breakers tripped. Or, the receptacle itself may be bad. If you confirm you have the correct voltage at the receptacle, your power cord may be bad.

The reason the clock and display will still appear to work is because the clock only uses 110-120VAC and is tapped off the source voltage. The surface burners and the oven heating elements, however, require the full 220 service.

If you are confused by this explanation, please post back and let me know. Hopefully, this is a problem that will not require any parts or a service call. If the power cord is bad, you can purchase a replacement at any hardware store. I hope this information is helpful.

My ifb microwave oven is getting hot outside while


Normally when u cook food in microwave the fod is cooked by microwaves, which means the heat is generated with in food. The temperature inside is never too hot and all the heat produced is absorbed with in the food.

On the other hand when the grill is switched on, a separate heatting element gets switched on. You can see this red hot element on the top side of inside of microwave. the heat from this element gets transferred to food through air circulation. But partof heat also gets transferred to the walls of microwave oven. This is the reason the wall feel hot during use of grill.

As i see ther is no problem with the microwave itself. Jut kep delicate thngs a bit away from the microwave.
