I have a whirlpool oven not sure of the model. The burners can get red hot on a low setting. Do I have to replace the burners?

First thing I would check is see if you are getting 220 volts to the stove.  Must be a constant 220.  Let me know what you find.

Get the installation manual for your range, and find the part on adjusting the low heat for the burners. On my Whirlpool, I found there is an adjustment screw inside the control knob shaft of each burner. The manual says turn the burner on low, remove the knob, then turn this screw until the flames are 1/4" high. Super-easy, it took me 5 minutes to do. I am sure all ranges have similar adjustments, might be in different locations - check the manual.

Hi, It sounds like the ignitor has gone bad. Remove the floor panel in the oven and locate the ignitor fastened to the burner. There should be 120V going to the ignitor harness.
If you have voltage but no ignition, change the ignitor.
I hope this helps you. Please let me know if I can assist you further.

Since you do not have a thermostat control on your burners, I would suspect you may have an infinite switch (burner control), that controls that particular burner, possibly starting to go bad. The thermostat control is located on the infinite switch itself and may be cycling on and off improperly. Its hard to tell with intermittent problems, however. If in doubt, you can do a comparison between a working 8" inch burner and the one you are having problems with.

Another thing to consider with these coil type plug in burners, the receptacles under the cook top that they plug into can gradually become loose over time and cause the burners to arc. This may also cause excess current flow through the burner and will eventually cause burner coil damage and/or receptacle failure. I would troubleshoot this by, first, by unplugging the appliance and inspecting all the burner receptacles. If any show signs of burning or melting, replace them. You will need to lift the cook top to access them. Locate the screws under the bottom front edge of the cook top (open the oven door to see them) and remove them. With the screws removed, the cook top will lift up. Prop in place using the hinge supports.

NOTE: Remove the burner coils and bowls before lifting the cook top.

Replacements parts (including burner receptacles) can be purchased at pcappliancerepair.com, appliancepartspro.com, searspartsdirect.com, or repairclinic.com.

If you have any questions, please let me know. I hope this helps you.
