I have a GE Profile radiant cooktop (Model No. JP345 2S2WG - Serial No. SL742063R).
We had a spillover and liquid got in the control area. After that, the “Unit On" indicator light (not the "Surface Hot" indicator light) was dimly glowing even through all the burners were off. If I cut a burner on the "Unit On" light turned brighter as it normally would be when a burner was on.
I opened the cooktop up and saw liquid was under the switch panel so I dried it out (towels & fan). After reassembly, the glow on the "Unit On" light was initially off but later came back on.
I read a post on another forum that suggested testing the circuit on each infinity switch by unplugging the violet wire on all 4 of the switches. I tried it switch by switch. After removing the wire from the first one (switch still glowing) I put the wire back on switch 1 and then removed the violet wire from switch 2 to isolate each switch.
I ran thru all four switches and the "Unit On' light stayed dimly glowing through all four violet wire removals.
Any other suggestions?
