check them with a meter and check the infinite switch's also Surface burners are typically either a coil type, solid type or a ribbon coil as used in smooth top ranges. All of these consist of a heating wire that uses electric current to produce heat. Coil type elements can be checked for continuity by removing them from the terminal block and testing them with a multi-meter. You should also inspect the terminal ends for signs of heat damage or corrosion, and if present, you should replace the terminal block or receptacle at the same time. You will need to remove power from the range to change the terminal block. Solid elements and smooth top elements require raising or removing the main top to gain access. You will need to remove power from the range before lifting the main top. Continuity can then be checked with a multi-meter, once you have removed the wires from the element terminals. 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 for overheated 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. 2.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. 3.Set your multimeter to 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. 4.Repeat the step above for the terminals "L2" and "H2". 5.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. 6.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. 7.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. )

Look up the front panel at an appliance supply store- copy the pattern and go from there, or buy the new panel with new markings...

I would suggest checking either the heating elements themselves (unlikely since it's both) and also checking your thermostat, temp switch, as well as the adjusting knobs. the knobs themselves have a tendency to get gunked up and not provide proper connection. atleast in my experience in a commercial kitchen environment.

Need model number from serial plate in order to help you

I need the model number from the serial plate in order to help you.

This will work for you. WB21X5301. When you get the part, snipp the plug of the old one if the new one doesn't fit, it has ceramic wire nuts to connect the old plug to the new sensor re-install and your golden.

In the power panel on your house. There are two circuit breakers with their handles joined.One of these breakers has tripped internally which will stop the heating elements but not the control panel or oven light since they work on 120 volts. Reset the breaker or replace it.

You should get a new one or re download it

the key sign shows that the child lock is engaged. to unlock, usually you push and hold the lock button for a few seconds. the correct button is usually a dual function and so marked. if you need more help, go to manualsonline.com and look up your model number for your manual. good luck

Have you checked your elements? They could be going bad otherwise your oven control board is going bad and needs to be repaired. The Repair Shack offers a service which can fix this issue of the problem is in fact the Conteol Board.
