I was having problems with my gas furnace. I replaced the ignitor which failed but it seems the ignition control may be locked out. Can they be unlocked or do they have to be replaced?I notice there is no power coming out of the ignition module to fire the ignitor. Any thoughts would be appreciated. n8

Simply turning the power off and on resets the furnace lockout status. There is something else going on. Check pressure switch and foor bad connections to the ignitor.
