Furnace will not start at all; no lights on control panel and no fans run.

Safety first: Before resetting breakers or replacing fuses, ensure your hands are dry and you are standing on a dry surface.

Steps:

• 1. Check household breaker: Locate the breaker feeding the furnace circuit and reset it if tripped. If it trips again immediately, stop and call an electrician or technician.
• 2. Inspect power cord and outlet: Verify the furnace is plugged in securely and the outlet has power (test with a lamp or meter).
• 3. Check furnace fuse: Many US Stove furnaces have an inline or board-mounted fuse. With power disconnected, remove and inspect the fuse. Replace only with the same type and rating.
• 4. Verify main power switch: Ensure the on/off switch on the furnace is in the ON position and not damaged. Replace the switch if it feels loose or does not latch.
• 5. If still dead: If there is confirmed power at the outlet and fuse, but the unit remains dead, the control board or internal wiring may be faulty. Contact a qualified technician.
