DIY Update

I realized that I never issued a DIY update on my HVAC.

Background, the AC had ceased. I checked the usual issues and found nada. The A/C capacitator worked. 240 was reaching the unit. Nothing was coming from the thermostat.

After replacing the furnace’s stepdown transformer for the furnace and the furnace control panel and seeing no success, I tested the furnace cover’s safety switch. No power there. I tested the power into the junction box. No power.

The switch for the furnace is mounted on the wall not far from the furnace, right above the entrance into the space as you climb up the ladder from the garage. Not an easy access space. To check that box, I’d need to throw the circuit breaker for the furnace. That would kill any useful light in the attic space.

I mounted my trouble light up there on a rafter. Connecting it with an extension cord, I plugged it into a garage wall socket below. Light was restored. My largest concern was that my right ankle would roll on me while I was standing on the ladder. Although I wore a brace on it, it weighed on my mind. I imagined it rolling and toppling off the ladder. Such an imagination. I should write fiction.

Pulling the cover off the switch, I discovered the quick connects in it fried. Replacing the unit was short work after purchasing a new one.

Job done. Just in time for cold nights and morning. Really satisfying to hear that furnace start and run.
