Kenmore Gas Range Does Not Heat


Hello,
I have a kenmore range and the broiler and oven do not heat up 50% of the time.
The stovetop always works but I get the following symptoms with the range and broiler half the time:
1. press BAKE
2. no "click" then ignite in the oven or broiler.
3. If I let it sit for an hour or so sometimes it does ignite...
I complained to Sears and they sent me a brand new stove but it has the same issue. Could it be the wiring in my home?
Any ideas appreciated...

Try taking a look at this web page and see if anything sounds familiar:

PS.......It's generally a good idea to post the model number of the unit you are enquiring about. :-)

Thanks,
The model is Kenmore 665 75829000 - does that narrow down the problem?
What really confuses me is that I have the same issue with two stoves...

The number 665 points the unit being made by Whirlpool for Sears.

The following is from the website reference I sent you previously:

Spark Ignition Systems Spark
Conventional
Oven models using a 'conventional' spark ignition system also have an actual gas pilot but it is not lit all the time. Instead, when the oven is turned on gas flows to the oven's pilot which is lit via a spark. Once the pilot is lit, a gas valve senses it and allows gas to flow to the oven burner where the pilot flame ignites it.
Whirlpool Direct Spark Ignition (DSI)
Whirlpool has introduced a new variation on the spark ignition system. In this system there is no 'pilot', instead the spark directly ignites the gas burner (hence the name) and an additional electronic control monitors its performance.
When the range control calls for either bake or broil, the DSI module electronically checks both gas valves' solenoids for continuity. If the checks fail, the module will turn the oven off or lock it out. If the checks are successful, the module will power the appropriate gas valve so it can open and also initiate sparking at the burner ignitor. Both the bake and broil ignitors will spark simultaneously.
If no flame is present at the burner, the DSI module will allow the ignitor to spark for 4 seconds. A 30 second pause will then occur, after which time it will attempt to light the burner again. If gas still fails to ignite, the microcomputer will then lock the system out.
Once gas has ignited, the flame sensing circuitry will monitor the flame at the burner as long as it is powered to make sure that it is present. If at any point no flame is detected, the DSI module will lock out the system.
On such a system the oven will not light for 30 seconds after power is restored to the appliance. Also, if no ground is found in the power connection to the range (or just at the DSI control), the oven will light once but them turn off and be 'locked out'.
Whirlpool's DSI system will likely only be found on Whirlpool's brands of appliances such as Whirlpool, KitchenAid, Roper and Inglis as well as some Whirlpool built Kenmore ranges and ovens.

They didn't try to fix the one you have? Was this brand new at the time?
