Question and Answers

Q:

Gas Oven not lighting or giving error message

A:

The Kenmore range is an appliance we definitively depend on and when part of it does not work it is a concern. I did some research on managemylife.com and found links with expert answers that addresses the most common problem with other ranges. Hope this helps. The expert will be with you shortly.

A:

I assume that the control panel works and that the digital display is lit up. If not, then I recommend that you check the house circuit breaker for the range and the electrical outlet.

If the range definitely has power then you likely have a component failure. Since that igniter is not glowing at all, you could have a bad igniter, a failed safety gas valve, a bad clock control board, a bad temperature sensor probe or a wiring failure in that circuit.

If you have a volt/ohm meter, then you can unplug the range and check the continuity through that ignition circuit. You can access that clock control board as shown in this brief repair video: Range Clock Control Replacement . You don't have to remove that clock control board to check the resistance through that ignition circuit. The wiring schematic in the image below shows that ignition circuit marked in yellow and white (the actual wire colors that you should see). You can pull the connector off of the control board and check the resistance through the yellow and white wires. You should measure between about 40 and 400 ohms through that circuit (the resistance will vary because the ignitor resistance depends on its temperature). You should at least measure continuity (some resistance value). If you measure an "open" circuit (Ol -- open load or infinite resistance) then you will need to check the igniter and the safety gas valve directly at those components. If the resistance through that circuit measures continuity, then I recommend that you check that sensor circuit (through the violet wires). That sensor circuit should measure around 1100 ohms at room temperature. If the sensor is bad, then it will need to be replaced.

You can order parts from this link: Kenmore Gas Range 790.71202703 Parts . Be sure that you unplug the range before accessing and replacing internal components.

These initial troubleshooting tips may help you fix that ignition problem in your range. If you need more assistance, reply with additional details.

If you get to the point where you need to have a service technician diagnose and repair this failure, you can schedule service through this link: Sears Home Services .
