      The issue might stem from a blown fuse or tripped circuit breaker, a furnace power switch being set to OFF, or the furnace blower compartment door/panel not being properly installed. To resolve this, replace the fuse or reset the breaker, ensure the furnace power switch is ON, and correctly replace the door panel to engage the safety interlock or door switch.
