I'm trying to convert a gas dryer back to natural gas. I've purchased the proper orifice an installed it on the regulator/burner unit. Other online instructions say that I now have to switch the regulator by either turning the set screw back to "N" (which does not appear anywhere on the burner unit) or by turning the "towers". This is where I'm stumped because the posts that stick out are protected by a plate that is screwed down with safety torx screws and appear to be there as valve units that are permanent. How do I convert the regulator so we get a gas flow to the glow plug head when the dryer is turned on?

Point to the online instructions, Since there are tamper prrof screws, there are tamper proof screwdrivers. The local auto store sells a set of torx sockets for about $10.00.

Who knows why GM, now Government Motors put tamper proof torx on their MAF (Mass Air Flow) sensors. Totally cluless. Also clueless that you need a 5.5 (5/32") mm swivel socket to remove a blower resistor.
