Recently replaced the vaccuum switch on my FPI, and since re-firing, the room fan won't shut off even when the stove is completely cooled down. any ideas?
 
Whatever senses the stove is up to temp may be defective, or its wiring. It may be a snap switch or thermocouple; I'm not familiar with your stove. If you have a snap switch, try taking one wire off of it (with the stove unplugged), then try. If the fan doesn't run, you've found your problem. Also check for pinched/chafed wiring in the area you were working in, since the problem occurred after your work.
