Maytag MGC5536BDS SS Gas Cooktop, Igniter insulator cracked

[sabre193]

Hi, I've got a Maytag stainless steel gas cooktop, model # MGC5536BDS.  The insulator on the front right burner igniter has cracked.  I want to replace the igniter (part # WP8523793) but I have a problem.  I believe I need to remove the burner head to access the igniter (which seems to be is screwed into the orifice holder underneath), but the screws holding down all the burner heads are badly corroded. 

Without a manual, I can't tell for sure, but I believe I have to remove all the burner heads in order to lift the stainless steel cooktop, in order to access the screw holding the igniter.  If I try to drill out the burner head screws, I suspect that I'll likely damage the threads of the orifice holders and wind up having to replace them too, along with all the screws.  That will get expensive very quickly and mean replacement of the whole cooktop will be more cost-effective than repairs.

I've looked underneath the unit and don't see any other access.  Is there some other way for me to access the igniter for replacement without having to drill out the burner head screws?  If not, is there something I can use to repair/seal the insulator on the igniter that would be safe to use?  Other ideas or suggestions are appreciated.  In the meantime, we are just using a match/lighter to light that burner.  Thanks in advance!

In my opinion , yes.    But Nothing wrong with getting the good out of it by using a lighter

Other than it can be dangerous, especially if you have young children in the household. 

Gas gets turned on and no one knows it.

agreed .  I think it is dangerous around kids even when it is working properly cause they will go past the lite position before it lites and the same thing will happen . some of the new stuff may have safeguards against that but oldschool cooktops can mess up someones day    !
