Watch on YouTube

What happens here

The electrician arrives for an emergency service call as the customer has no heat. He first inspects the existing Honeywell Home thermostat, which shows no display, indicating it's not functioning, even after the customer attempted to change the batteries. He then proceeds to the electrical panel, checks that all circuit breakers are in the 'on' position, and confirms there are no tripped breakers. Finally, he verifies that the furnace itself is powered on and running.

Goal: Diagnose the cause of the no-heat problem.

Tools and materials

  • Electrical Panel — Inspecting circuit breakers for power issues
