Regarding a 1994, Trane TUC080C942A0, natural gas furnace.
I can't locate the fuse in the unit.
I attempted to look at the main board but it appears to be sealed. To confirm, access to the fuse requires the cover to be removed from the main board?
Any experiences with where the fuse is located on these units?
While testing a limit switch, my jumper cable shorted and sparked. Now, the blinking light flashes a steady slow flash even when the thermostat is calls for heat. (This means idle waiting for call of heat.) As a result, the inducer’s fan will not respond.
