Hi all,
November was my last camping trip, furnace wouldn't fire. Fan would come on, but wouldn't trip the ignitor. After tinkering, pulled the high limit, joined the wires with a marrette, worked just fine for the weekend.
Over the winter, ordered a new high limit and sail switch. Just replaced both, fan will spin, won't trigger ignitor. I'm testing 12v on one side of the sail switch, but only 0.25v on the other with the fan going.
If I pull the sail switch and manually squeeze it with the fan running, it triggers the ignitor, and the furnace fires every time. What would cause the sail switch to fail to activate inside the blower assembly?
