Question and Answers

Q:

Burner and Oven Issues 7909421940A Kenmore Electric range

A:

I know that it can be very difficult to have issues with your range. The surface elements require 220-240 volts in order to heat properly. The surface element switch needs to have L1 voltage (120 volts) and it must have L2 voltage (120 volts). When the surface element switch is turned on, there must be 120 volts supplied to H1 and 120 volts supplied to H2 which is the circuits connected to the surface element receptacle. You will need a volt meter to check and verify voltage (220-240 volts) when measuring across L1 and L2 on the switch and you will need to check and verify 220-240 volts when measuring across H1 and H2 on the switch. If you measure 220-240 volts across L1 and L2 and your not measuring 220-240 volts across H1 and H2, replace the burner switch. If you don't feel comfortable doing this yourself, please click on this link to schedule service: Sears Home Services. Click on "Get Started" and follow the directions, click on the red "NEXT" button to continue. I hope this helps. Please feel free to let me know if you need further assistance.

Thank you for your question and I understand your concern. The surface elements require 220-240 volts in order to heat properly. The surface element switch needs to have L1 voltage (120 volts) and it must have L2 voltage (120 volts). When the surface element switch is turned on, there must be 120 volts supplied to H1 and 120 volts supplied to H2 which is the circuits connected to the surface element receptacle. You will need a volt meter to check and verify voltage (220-240 volts) when measuring across L1 and L2 on the switch and you will need to check and verify 220-240 volts when measuring across H1 and H2 on the switch. If you measure 220-240 volts across L1 and L2 and your not measuring 220-240 volts across H1 and H2, replace the burner switch. I added an image below of the surface element circuit. NOTE: I do not recommend checking and confirming voltage unless you have experience and feel safe and confident in doing so, otherwise I recommend calling a service technician to diagnose and repair your range . If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:Sears Home Services .

Making repairs and being left with the same problem would be upsetting. The expert does review and respond within 24-48 hrs. Could be sooner. In the meantime I found a previous expert post that has some checks you may want to consider. Hope this helps!

I referred to your previous question and see that you have range model 790.9421940A.

See if the burner light turns on when you set that burner to heat. If not, then you could have a problem with the burner switch. A problem with the simmer select control board could prevent the left front burner from heating. If the burner light turns on, I recommend that you unplug the range and check the simmer select control board in the console for a burned spot. You can remove the upper back panel to access this control board. If the simmer select control board is damaged, then you will need to replace that component to fix the burner. The part number for the simmer select control board is 316429301. You can order that part from the Sears PartsDirect website. That part costs around $25.

If the simmer select control board is okay, then you will probably need to replace the burner switch. A problem with the wiring can also cause this failure.

These tips may help you fix this burner problem. If you need more assistance, reply with additional details.

I checked the simmer select wires and control board and did not see any burn mark. The light for the burner and simmer select do work. I think the simmer select button may have been on when the pop and flash occured. Is there anyway to bypass the simmer select?

A:

There is not a way to safely bypass the simmer select control board. When the simmer select button is not activated, the L2 voltage supply to the burner switch should be completed as shown in the image below. Your symptoms point to a failure in that simmer select control board. As noted in the above response, that control board costs about $25. I recommend that you take a chance and replace that simmer select control board to see if that fixes your problem. If not, reply with additional details and we will assist you further.
