Stove top Wire Harness

Hello,

I was wondering if you can replace only one switch from the wire harness switches (consists of 5) for Whirlpool Stove top model GLT3657RQ01. The harness number at appliancePartsPro is Ap3592411. The switch number on the part is STM 30100-2 (9755452). Do you sell this part by itself?
I also want to know what cause it to smok (Burn) was it water maybe when the stove was cleaned?
Thank you

I have same issue. Looking to replace that same switch, but unable to find it so far.
