Home-visit safety checklist: smoke and CO alarms, GFCIs, dryer, water heater and appliance basics

A short list you can run in 20-30 minutes and leave in writing. USFA says to test smoke alarms monthly and replace each unit at 10 years; CPSC says to test CO alarms monthly and change replaceable batteries at least yearly; Leviton says to press TEST then RESET on every GFCI monthly. Add the dryer lint path, water heater T&P discharge, washer hoses, garage door reversal and appliance cords. You inspect and record; you do not repair gas or service panels as part of this list.

Before you start

Warn occupants before testing alarms; they are loud
If a CO alarm is sounding or anyone has headache, nausea or dizziness, get everyone out and call 911 or the gas utility from outside
A GFCI that will not trip or reset is a hazard; tag it and recommend a licensed electrician if wiring is suspect

Blower runs nonstop and no cooling on a new HVAC system: A2L refrigerant leak sensor

A2L systems carry a refrigerant leak sensor near the indoor coil. When it reports a leak, or when the sensor fails or loses communication, the control stops the compressor and runs the blower to dilute any refrigerant. This guide separates a sensor or wiring fault from a possible real leak; any real leak is referred to an EPA 608 technician.

Confirming an inverter board's DC bus is discharged before you touch it

Inverter boards store high-voltage DC in large capacitors after the power is off, and a dark LED does not mean the board is safe. Remove power, wait the maker's time, then measure the DC bus at the marked test points until it reads 0 V. Only then unplug loads or handle the board.

Load will not turn off: shorted triac or welded relay (board vs load)

When a load runs with no command, the board output that feeds it is usually shorted: triacs most often fail shorted and relay contacts can weld closed after inrush. Confirm the output is truly on with the load connected (not a ghost reading), then test the load itself, because a shorted or seized load is what usually kills the output.
