For this job, we came out to look at a gas furnace that was not functioning. The furnace is quite a bit older, however, the integrity of the electrical still intact. Tested the line voltage from the breaker coming into the switch at the furnace and turn the switch on showing the power is passing through into the furnace however, the furnace would not ignite. We determined that the issue was not electrical, luckily he has a body who does HVAC that is helping him out as well. Additionally, we noticed no whole home, surge protection, and the panel, nor was there a hot/cold/gas bonding jumper on the the water heater and gas pipe. Estimated those safety suggestion updates.
