Jenn-Air Electric stovetop / oven range SCE4340B - Fuse blown ? ? ?

The infinite switch
on the control panel controls the power to each surface element. If you have no heat at an element and the element and terminal block check ok, then you may have a defective infinite switch. Disconnect power to the range and remove the console back panel. Locate the switch and check foroverheated wires or faulty terminals first.Test the switch's contacts for continuity with a multi-meter. If defective, replace the switch.

1. If the infinite switch does not appear to be defective, then you should check for proper voltage to the switch. This is a live high voltage test and should only be performed by qualified persons.(Locate the suspect switch for testing. Label all wires and terminals before disconnecting. A close up digital photo may be helpful.

1. On the burner control switch the terminal labeled "P" leads to the burner indicator light. The terminals labeled "H1" and "H2" lead to the burner element and the terminals labeled "L1" and "L2" (sometimes "N1" and "N2") are the power supply wires.

1. Set yourmultimeterto ohms setting x1. Turn the burner control to the highest temperature setting. Place one probe on pin "L1" and the second probe on pin "H1". The resistance measurement should be very low, zero to twenty ohms. If the test shows high or infinite resistance, the burner switch is defective.

1. Repeat the step above for the terminals "L2" and "H2".

1. If the control passes that test, turn the temperature setting to about the middle of the range and repeat the previous two steps. This will test for an intermittent problem with the switch. If the test does not show continuity with very low resistance, the switch should be replaced.

1. With the switch turned to the "Off" position, the resistance on each of the pairs of terminals tested above should now show no continuity or a reading of infinite resistance.

1. A test for continuity between "P" and "L1" when the burner control switch is on should show continuity. The light should be on whenever the control is turned on. If your test shows continuity, but the light does not operate, it is likely the bulb has failed.

If the burner switch shows high or infinite resistance, the switch is not passing along current to the burner and so the switch should be replaced. )

Most modern ovens usean electronic control board
to control the oven functions. These models will use the control board to operate the oven safety valve on a gas range or oven, and the bake and broil elements on an electric range or oven. If there is no power to the igniter circuit, or the element circuits, then you should check the control board to verify that there is power at the appropriate output relay. These are live voltage checks and should be performed by qualified persons only. If there is no output voltage then the control should be replaced.

This is the first result I found; it may not have the best price:

The site also lists blower motors, but be sure to verify that the motor is defective before ordering; they are very expensive.

either the gas valve for that particular burner isnt opening,or if all burners are like this then the dual valve that feeds the broiler and stovetop has a bad stove top side of valve portion its underneath the oven cavity behind the lower pan drawer

Hi,
Here is a tip that I wrote to help people troubleshoot problems with their cooktops not igniting.

The switch for the burner is bad and needs to be replaced.

Just change big fuses in box.

YES THEY USE DIFRENT SWITCHES AND IF THE 1 YOU HAVE PROBLEN IS THE DUAL BURNER THER IS A SERVISE FLACH ON IT YOU NEED TO GO TO SERVISE MATER.COM AND FIND THE UPGRATE

There is no fuse on the unit. I suspect your house circuit is blown. If not, then a wire may have burnt off. Hope this helps!

the unit doesnt have any internal fuses. you have a house fuse blown or circuit breaker that tripped. the fan switch can be found online or from your local parts house and make sure you get the clips to hold it to the mounting tabs.
next time you get ready to work on it, just make sure and turn off the power first as you will touch the metal terminals to the frame again.

try to clean the burner and then try it.
