The other day I was going about my business doing the dishes and taking care of some other chores around the house when I all of sudden felt chilly. I guess I had not noticed that it was getting progressively cooler in the house because I was in the middle of chores, but when I did I went over to check the thermostat. According to the thermostat it was 63 degrees inside but the furnace was set for 70 degrees. I tried flipping the switch off and on again, but nothing happened. It was at this time that I realized that something was wrong with the furnace. I went into the basement to inspect the furnace. Nothing looked out of place so I decided to reset the igniter to see if that would help. I turned off the circuit breaker and switched the igniter off for five minutes as it says in the instruction manual. After five minutes I switched the power back on and turned the furnace on at the thermostat. Still nothing. Either the igniter was shot or something else was wrong. As I had not an inkling of how to proceed from here I called an HVAC professional to take care of it. The HVAC technician seemed impressed by the one thing I did and told me I should look into a career as a HVAC technician. He went through a bunch of tests and figured out that something was fried on the circuit board. That is something I would have never even thought about examining.
