Glad I could be of help.. NOW. Just because the sail is not sailing does not mean the switch is toast.
The fan has to blow hard enough to sail it.. (low battery, and the thing I missed is a poor 12 volt connection on the supply side) also if you have heat registers blocked, or say covered with a throw rug or bath mat.. That can keep it from sailing.
But .. At least you now know where to start looking.. Again Glad I could help, thanks for letting us know what it was.
And to the person who said Compairing Pilot light devices to DSI is like a Bread Machine to a rolling pin (you do not use a rolling pin making bread) I agree, which is why I stated the document I published applied ONLY to DSI, not to Pilot Light. Or did you miss that.
