Cooktop burner will be dim and red automatically

Go to settings, Power Saving Mode, If the brightness is checked uncheck.

I assume you are talking about general pilot light which illuminates when you turn any of the four hotplates on. This light gets its power supply from the hotplate contollers. The controllers generally have a pilot light circuit which links all 4 controllers to the pilot light. I haven't seen this problem before. Either a small amount of power is escaping across the pilot light contacts inside the controller or the pilot light is getting a feedback from another source/fault in the cooktop. The only solution is to dismantle the cooktop and use a voltmeter or similar to trace the fault. Unless you understand how the problem occurs it's probably best to call a repairman.

I'm having the same problem! Except I'm not guarenteed any heat even on high.

Bad control or infinite switch. replace the switch for that element and you will be good to go.

The burner control is failing for each burner. That model takes part #316021500 for the 6" units and part #5303935086 for the 8" unit.
This must be an older range, as Frigidaire lists the 6" switch and no longer in production. You can replace a 6" control with an 8" but not the other way around...

Hope this helps. Please rate my answer if this is the case.

Sounds like the Switch or the element are bad, try trouble shooting them. It's a stove top??

You'll need to replace the burner switch. This happens when the contacts become fused together.

you need a new switch that is in the control panel

first, disable power to cooktop. next, replace either the mangled burner or the entire unit (after initial inspection leads to a logical prognosis)...sorry.
